(09/28/2011) After the Arctic sea ice extent hit its second lowest size on record this summer—or lowest (depending on the source)—comes another climate change shocker: in the past six years Canada's millennia-old ice shelves have shed nearly half their size. One ice shelf—the Serson shelf—is almost entirely gone, while another—the Ward Hunt shelf—has split into two distinct shelves. The ice shelves have lost 3 billion tons in this year alone.
Northwest Passage open as sea ice falls to lowest cover ever recorded
(09/12/2011) Arctic sea ice cover fell to its lowest level on record, report researchers from the University of Bremen.
Mass walrus haul-outs, polar bear cub mortality linked to climate change
(09/01/2011) Recent, unprecedented walrus haul-outs and increased instances of long-distance swims by polar bears show the direct impacts on wildlife of dwindling Arctic sea ice from climate change. These threatened species also face the prospect of offshore drilling in the Arctic after the Obama Administration recently approved a number of plans to move forward on oil exploration. At least 8,000 walruses hauled out on an Alaskan beach along the Chukchi Sea on August 17. Only a day before, the U.S. Geological Survey announced it would begin tagging walruses near Point Lay, Alaska to study how a lack of sea ice is affecting the species.
Climate change may fuel increase in warfare, finds study
(08/24/2011) Civil war is twice as likely in tropical countries during particularly hot and dry years, according to a new study in Nature. The researchers found that El Niño conditions, which generally cuts rainfall and raises temperatures in the tropics, may have played a factor in one-fifth of the world's total conflicts during the past 50 years. El Niño conditions occur every 3-7 years. While the study did not examine global climate change in conjunction with conflict, the study links a warmer world to a more conflict-prone one, as least in the tropics.
Reducing Disaster Risks: Progress and Challenges in the Caribbean Region
(08/23/2011) Disaster management is a global policy problem with a critical land-use change component related to settlement patterns, deforestation, and agriculture development. This is further exacerbated by climate change.
Lessons from the world's longest study of rainforest fragments
(08/15/2011) For over 30 years, hundreds of scientists have scoured eleven forest fragments in the Amazon seeking answers to big questions: how do forest fragments' species and microclimate differ from their intact relatives? Will rainforest fragments provide a safe haven for imperiled species or are they last stand for the living dead? Should conservation focus on saving forest fragments or is it more important to focus the fight on big tropical landscapes? Are forest fragments capable of regrowth and expansion? Can a forest—once cut-off—heal itself? Such questions are increasingly important as forest fragments—patches of forest that are separated from larger forest landscapes due to expanding agriculture, pasture, or fire—increase worldwide along with the human footprint.
Arctic sea ice in free fall: new record low for July
(08/10/2011) Average Arctic sea ice extent hit a new record low for July according to the National Snow and Ice Data Center (NSIDC).If the melt continues apace, the sea ice extent could hit its lowest point since record keeping by satellite began 32 years ago. However, ice loss slowed through the second half of July as weather grew colder in the Arctic, and by the end of the month was slightly above conditions in 2007, in which the lowest sea ice extent ever was measured.
Famine spreads: 29,000 young children perish
(08/04/2011) As the UN announces that famine has spread in Somalia to three additional regions (making five in total now), the US has put the first number to the amount of children under 5 who have so far perished from starvation in the last 90 days: 29,000. Nearly half of the total population of Somalia is currently in need of emergency food assistance. Yet, the al Qaeda-linked group al-Shabaab, which controls parts of Somalia, has made bringing assistance to many of the malnourished incredibly difficult, if not impossible. The famine in Somalia has been brought-on by lack of governance combined with crippling droughts throughout East Africa, which some experts have linked to climate change. High food prices worldwide and a lagging response by the international community and donors have made matters only worse.
Chart: US suffers record drought
(08/01/2011) An exceptional drought is still scorching major parts of Texas, New Mexico, Oklahoma, and Louisiana. A new report from the National Drought Mitigation Center finds that over July, nearly 12 percent of the US saw exceptional drought conditions, the highest record since monitoring began a dozen years. Exceptional drought is the worst possible on a 5-scale drought scale.
Yellowstone burning: big fires to hit world's first national park annually by 2050
(07/25/2011) An icon of conservation and wilderness worldwide, Yellowstone National Park could see its ecosystem flip due to increased big fires from climate change warn experts in a new study in the Proceedings of the National Academy of Science (PNAS). A sudden increase in large fires—defined as over 200 hectares (500 acres)—by mid-century could shift the Yellowstone ecosystem from largely mature conifer forests to younger forests with open shrub and grasslands.
'Heatwave' in Arctic decimating sea ice
(07/21/2011) Arctic sea ice could hit a record low by the end of the summer due to temperatures in the North Pole that are an astounding 11 to 14 degrees Fahrenheit (6 to 8 degrees Celsius) above average in the first half of July, reports the National Snow and Ice Data Center (NSIDC). Already the sea ice extent is tracking below this time in 2007, which remains the record year for the lowest sea ice extent. The sea ice hits its nadir in September before rebounding during the Arctic winter.
Tens of thousands starving to death in East Africa
(07/20/2011) As the US media is focused like a laser on theatric debt talks and the UK media is agog at the heinous Rupert Murdoch scandal, millions of people are undergoing a starvation crisis in East Africa. The UN has upgraded the disaster—driven by high food prices, conflict, and prolonged drought linked by some to climate change—to famine in parts of Somalia today. Mark Bowden, UN humanitarian coordinator for Somalia, has said that tens of thousands Somalis have died from malnutrition recently, "the majority of whom were children."
Climate change to push over 10 percent of the world's species to extinction by 2100
(07/11/2011) Scientists have predicted for decades that climate change could have a grave impact on life on Earth, which is already facing numerous threats from habitat loss, over-exploitation, pollution, invasive species, and other impacts. However, empirical proof of extinctions--and even endangerment--due to climate change have been difficult to come by. A new study in the Proceeding of the National Academy of Science has found that by the time today's infants are 90 years old (i.e. the year 2100) climate change could have pushed over 11 percent of the world's species to extinction.
Worst drought in 60 years brings starvation fears to East Africa
(06/30/2011) A prolonged drought in East Africa is bringing many of the region's impoverished to their knees: the World Food Program (WFP) is warning that 10 million people in the region are facing severe shortages. While not dubbed a famine yet, experts say it could become one. Meanwhile, a recent study by FEWS NET/USGS has revealed that the current drought is the worst in 11 of 15 East African regions since 1950-51. Worsening droughts are one of the predictions for the region as the world grows warmer.
Hot map hard to ignore: interactive map points out local climate impacts
(06/29/2011) A global interactive map has been developed by the Union of Concerned Scientists (UCS) to highlight climate impacts already occurring worldwide. From glacier melt risking water supplies in Bolivia to coral bleaching off the coast of Florida, the Climate Hot Map employs the best in climate science to bring home the impacts of global warming.
The truth about polar bears and climate change
(06/21/2011) Although scientists say innumerable species are threatened by climate change, polar bears have been the global symbol of the movement to rein-in greenhouse gas emissions. This is perhaps not surprising, since polar bears are well known to the public—even though they inhabit a region largely absent of humans—and they make a big impression. Their glaringly white coat contrasts with their deadly skills: as the world's biggest terrestrial predators, they are capable of killing a seal with single blow. When young they are ridiculously adorable, but when adults they are stunning behemoths. But that's not all. Unlike many other species, the perils of climate change are also easy to visualize in connection with polar bears: their habitat is literally melting away.
Ocean prognosis: mass extinction
(06/20/2011) Multiple and converging human impacts on the world's oceans are putting marine species at risk of a mass extinction not seen for millions of years, according to a panel of oceanic experts. The bleak assessment finds that the world's oceans are in a significantly worse state than has been widely recognized, although past reports of this nature have hardly been uplifting. The panel, organized by the International Program on the State of the Ocean (IPSO), found that overfishing, pollution, and climate change are synergistically pummeling oceanic ecosystems in ways not seen during human history. Still, the scientists believe that there is time to turn things around if society recognizes the need to change.
Greenpeace head arrested after nonviolent protest on Arctic oil rig
(06/19/2011) Kumi Naidoo, the head of Greenpeace, has been arrested after scaling a deepwater oil rig in the Arctic run by Cairn Energy. Naidoo was attempting to deliver a petition to the captain signed by 50,000 people demanding that Cairn Energy release details on how it would respond to an oil spill. "For me and for many people around the world this is now one of the defining environmental struggles of our time," Naidoo said on a video before scaling the rig. "It's a fight for sanity against the madness that sees the disappearance of the Arctic ice not as a warning, but as an opportunity to seek further profits."
Arctic on the line: oil industry versus Greenpeace at the top of the world
(06/06/2011) At the top of the world sits a lone region of shifting sea ice, bare islands, and strange creatures. For most of human history the Arctic remained inaccessible to all but the hardiest of peoples, keeping it relatively pristine and untouched. But today, the Arctic is arguably changing faster than anywhere else on Earth due to global climate change. Greenhouse gases from society have heated up parts of the Arctic over the past half-century by 4-5 degrees Fahrenheit, leading to a staggering decline in the Arctic sea ice. The large-scale changes suffered by the Arctic have created a new debate over conservation and exploitation, a debate currently represented by the protests of Greenpeace against oil company Cairn Energy, both of whom have been interviewed by mongabay.com (see below).
Food security in developing world threatened by climate change
(06/06/2011) If swift action is not taken to prepare farmers in the developing world for hotter, drier, shorter growing seasons, climate change may threaten the lives of hundreds of millions of people by 2050. People in Africa and South Asia are particularly at risk of further impoverishment and hunger in a warmer world. According to the UN, a billion people are already going hungry worldwide.
New record in global carbon emissions 'another wake-up call'
(05/31/2011) Global carbon emissions hit a new high last year proving once again that international political efforts, hampered by bickering, the blame-game, and tepidity, are failing to drive down the greenhouse gas emissions that are causing the planet to heat up. According to the International Energy Agency (IEA), following a slight fall in carbon dioxide emissions due to the economic downturn, emissions again rose to a new record level in 2010: 30.6 gigatons. This is a full 5 percent higher than the past record hit in 2008. The new record puts greater doubt on the international pledge of limiting the global average temperature rise to 2 degrees Celsius.
Environmental law landmark: island nation challenges faraway coal plant for climate impact
(05/25/2011) The far-flung Federated States of Micronesia (FSM), located in the Pacific Ocean, has created legal history by challenging the decision to extend the life of a massive coal plant in the Czech Republic. The over 600-island nation, Micronesia, argues that greenhouse gas emissions from the Czech plant are impacting the way of life in Micronesia, many of whose islands are facing submersion under rising sea levels.
iPhone app uses Google Earth to track climate change impact on redwoods
(05/24/2011) The Save the Redwoods League is partnering with Google Earth Outreach and iNaturalist.org to connect citizens and scientists in an effort to track the effects of climate change on redwood trees and forests.
Climate change and deforestation pose risk to Amazon rainforest
(05/20/2011) Deforestation and climate change will likely decimate much of the Amazon rainforest, says a new study by Brazil’s National Institute for Space Research (INPE) and the UK's Met Office Hadley Centre. Climate change and widespread deforestation is expected to cause warmer and drier conditions overall, reducing the resistance of the rainforest ecosystem to natural and human-caused stressors while increasing the frequency of extreme rainfall events and droughts by the end of this century. While climate models show that higher temperatures resulting from global climate change will threaten the resilience of the Amazon, current deforestation is an immediate concern to the rainforest ecosystem and is likely driving regional changes in climate.
NASA Photos: beyond Mississippi flood, southern Africa sees record deluges
(05/12/2011) While record crests of the Mississippi River are creating havoc in the southern US, this is not the only region in the world facing unprecedented flooding. Huge rain events have produced floods in southern Africa as well, impacting Namibia, Botswana, and South Africa. Since last year rainfall has been above average in much of these regions, including a record deluge this month in Namib Desert, where more rain fell in just one day in than usually does in an entire year.
Burning up: warmer world means the rise of megafires
(05/12/2011) Megafires are likely both worsened by and contributing to global climate change, according to a new United Nations report. In the tropics, deforestation is playing a major role in creating giant, unprecedented fires.
Are US floods, fires linked to climate change?
(04/28/2011) The short answer to the question of whether or not on-going floods in the US Midwest and fires in Texas are linked to a warming Earth is: maybe. The long answer, however, is that while it is difficult—some argue impossible—for scientists to link a single extreme weather event to climate change, climate models have long shown that extreme weather events will both intensify and become more frequent as the world continues to heat up. In other words, the probability of such extreme events increases along with global average temperature.
Scientists scramble to save dying amphibians
(04/28/2011) In forests, ponds, swamps, and other ecosystems around the world, amphibians are dying at rates never before observed. The reasons are many: habitat destruction, pollution from pesticides, climate change, invasive species, and the emergence of a deadly and infectious fungal disease. More than 200 species have gone silent, while scientists estimate one third of the more than 6,500 known species are at risk of extinction. Conservationists have set up an an emergency conservation measure to capture wild frogs from infected areas and safeguard them in captivity until the disease is controlled or at least better understood. The frogs will be bred in captivity as an insurance policy against extinction.
With pressure to drill, what should be saved in the Arctic?
(04/27/2011) Two major threats face the Arctic: the first is global climate change, which is warming the Arctic twice as fast the global average; the second is industrial expansion into untouched areas. The oil industry is exploring new areas in the Arctic, which they could not have reached before without anthropogenic climate change melting the region’s summer ice; but, of course, the Arctic wouldn't be warming without a hundred years of massive emissions from this very same industry, thus creating a positive feedback loop that is likely to wholly transform the Arctic.
Warmer temperatures may be exterminating pika populations one-by-one
(04/21/2011) The last decade has not been a good one for the American pika (Ochotona princeps) according to a new study in Global Change Biology. Over the past ten years extinction rates have increased by nearly five times for pika populations in the Great Basin region of the US. Examining extinctions of pike populations in the region over the past 110 years, researchers found that nearly half of the extinction events occurred since 1999.
NASA image reveals extent of 2010 Amazon drought
(04/17/2011) NASA has revealed a satellite image of the crippling effect of last year's record-breaking drought on the Amazon ecosystem. For those of you counting, that's two record droughts in the Amazon Basin in 5 years.
Antarctic penguins losing to climate change through 80% krill decline
(04/11/2011) Climate change has hit species of Antarctic penguins by causing a staggering decline in their prey: krill. A new study in the Proceedings of the National Academy of Sciences (PNAS) has found that both chinstrap penguins (Pygoscelis antarcticus) and Adélie penguins (Pygoscelis adeliae) have seen their populations decline likely do to less krill, instead of habitat changes. Since 1970 krill populations have fallen by 80% in the Southern Ocean surrounding Antarctica. Because krill require sea ice to reproduce, shrinking sea ice from climate change has made it more difficult for them to breed.
'Huge reduction' of water from plants due to higher carbon levels
(03/30/2011) As if ocean acidification and a warming world weren't enough, researchers have outlined another way in which carbon emissions are impacting the planet. A new study shows that higher carbon dioxide levels in the atmosphere have taken a toll on how much water vapor plants release, potentially impacting the rainfall and groundwater sources. A study in the Proceedings of the National Academy of Sciences (PNAS) has found that carbon dioxide levels over the past 150 years has reduced plants' spores, called stomata, by over one third (34%). This is important because stomata take in oxygen and carbon dioxide and release water vapor in a process dubbed 'transpiration'. Less stomata means less water driven into the atmosphere.
Last year's drought hit Amazon hard: nearly a million square miles impacted
(03/29/2011) A new study on its way to being published shows that the Amazon rainforest suffered greatly from last year's drought. Employing satellite data and supercomputing technology, researchers have found that the Amazon was likely hit harder by last year's drought than a recent severe drought from 2005. The droughts have supported predictions by the Intergovernmental Panel on Climate Change's (IPCC) that climate change, among other impacts, could push portions of the Amazon to grasslands, devastating the world's greatest rainforest. "The greenness levels of Amazonian vegetation—a measure of its health—decreased dramatically over an area more than three and one-half times the size of Texas and did not recover to normal levels, even after the drought ended in late October 2010," explains the study's lead author Liang Xu of Boston University.
Climate change caused by deforestation triggers species migration
(03/23/2011) Local climate shifts caused by deforestation and land cover change are causing insects to migrate to higher — and cooler — habitats, reports a new study published in the journal Biotropica. The research has implications for predicting how species will respond to climate change.
15 conservation issues to watch
(03/14/2011) Deforestation, oil spills, coral acidification: these are just a few examples of ongoing, and well-researched, environmental changes that are imperiling the world's biodiversity. But what issues are on the horizon? At the end of 2010, experts outlined in Trends in Ecology & Evolution 15 issues that may impact conservation efforts this year and beyond, but are not yet widely known. These are issues you may never hear about it again or could dominate tomorrow's environmental headlines. "Our aim was to identify technological advances, environmental changes, novel ecological interactions and changes in society that could have substantial impacts on the conservation of biological diversity […] whether beneficial or detrimental," the authors write in the paper. Experts originally came up with 71 possible issues and then whittled it down to the 15 most important—and least known.
Birnam Wood in the 21st Century: northern forest invading Arctic tundra as world warms
(03/07/2011) In Shakespeare's play Macbeth the forest of Birnam Wood fulfills a seemingly impossible prophecy by moving to surround the murderous king (the marching trees are helped, of course, by an army of axe-wielding camouflaged Scots). The Arctic tundra may soon feel much like the doomed Macbeth with an army of trees (and invading species) closing in. In a recent study, researchers found that climate change is likely to push the northern forests of the boreal into the Arctic tundra—a trend that is already being confirmed in Alaska.
World's sixth mass extinction still preventable
(03/03/2011) So, here's the good news: a mass extinction, the world's sixth, is still preventable. But the bad news: if species currently threatened with extinction vanish—even over the next thousand years—homo-sapiens will be the first single species responsible for a mass extinction. Comparing today's current extinction crisis with the big five that occurred in the past, a new study in Nature finds that while the situation is dire, the choice is ultimately up to humanity. "If you look only at the critically endangered mammals—those where the risk of extinction is at least 50 percent within three of their generations—and assume that their time will run out, and they will be extinct in 1,000 years, that puts us clearly outside any range of normal, and tells us that we are moving into the mass extinction realm," explains lead author Anthony D. Barnosky, UC Berkeley professor of integrative biology.
Coral crisis: 75% of the world's coral reefs in danger
(02/23/2011) Marine scientists have been warning for years that coral reefs, the most biodiverse ecosystems in the ocean, are facing grave peril. But a new comprehensive analysis by the World Resources Institute (WRI) along with twenty-five partners ups the ante, finding that 75% of the world's coral reefs are threatened by local and global impacts, including climate change. An updating of a 1996 report, the new analysis found that threats had increased on 30% of the world's reefs. Clearly conservation efforts during the past decade have failed to save reefs on a large-scale.
Coal's true cost in the US: up to half a trillion
(02/20/2011) According to the global market coal is cheap, yet a new study in the Annals of the New York Academy of Sciences finds that the hidden costs of coal are expensive, very expensive. Estimating the hidden costs of coal, such as health and environmental impacts, the study found that burning coal costs the US up to $523 billion a year. Dubbed 'externalities' by economists, the paper argues that these costs are paid by the American public to the tune of $1,698 per person every year.
Not enough data on world's tropical plants to predict impact of warming world
(02/14/2011) How many tropical plant species are threatened by climate change? Which plants have big enough ranges to survive a warming world, not to mention deforestation? How likely is it that the tropics are undergoing a current mass extinction? These questions may appear straight forward, but a new study in Global Change Biology finds that researchers lack the hard data necessary to come to any confident conclusions. According to the study, nine out of ten tropical plants from Africa, Asia, and South America lack the minimum number of collections needed (at least 20) to determine the species' range, and therefore predict the impact of climate change.
Food crisis 2011?: drought in China could push food prices even higher
(02/09/2011) The UN's Food and Agriculture Organization (FAO) has warned that a drought in China could devastate the nation's winter wheat crop and further inflate food prices worldwide. Already, food prices hit a record high in January according to the FAO. Rising 3.4 percent since December, prices reached the highest point since tracking began in 1990. While many fear a food crisis similar to the one in 2008-2007, experts say the world has more food in reserve this time around and gasoline, at least for now, remains cheaper. However, if China loses its winter wheat that could scuttle any hopes of avoiding another price rise in crop staples.
Numerous causes, including climate change, behind record food prices
(02/07/2011) Food prices hit a record high in January according to the UN's Food and Agriculture Organization (FAO), threatening the world's poor. Rising 3.4% since December, the FAO stated that prices reached the highest point since the agency began tracking food prices in 1990. Given the complexity of world markets and agriculture, experts have pointed to a number of reasons behind the rise including rising meat and dairy consumption, the commodity boom, fresh water scarcity, soil erosion, biofuels, growing human population, and a warming world that has exacerbated extreme weather events like last year's heatwave in Russia.
The ocean crisis: hope in troubled waters, an interview with Carl Safina
(02/07/2011) Being compared—by more than one reviewer—to Henry Thoreau and Rachel Carson would make any nature writer's day. But add in effusive reviews that compare one to a jazz musician, Ernest Hemingway, and Charles Darwin, and you have a sense of the praise heaped on Carl Safina for his newest work, The View from Lazy Point: A Natural Year in an Unnatural World. Like Safina's other books, The View from Lazy Point focuses on the beauty, poetry, and crisis of the world's oceans and its hundreds-of-thousands of unique inhabitants. Taking the reader on a journey around the world—the Arctic, Antarctic, and the tropics—Safina always returns home to take in the view, and write about the wildlife of his home, i.e. Lazy Point, on Long Island. While Safina's newest book addresses the many ways in which the ocean is being degraded, depleted, and ultimately imperiled as a living ecosystem (such as overfishing and climate change) it also tweezes out stories of hope by focusing on how single animals survive, and in turn how nature survives in an increasingly human world. However, what makes Safina's work different than most nature writing is his ability to move seamlessly from contemporary practical problems to the age-old philosophical underpinnings that got us here. By doing so, he points a way forward.
Two massive droughts evidence that climate change is 'playing Russian roulette' with Amazon
(02/03/2011) In 2005 the Amazon rainforest underwent a massive drought that was labeled a one-in-100 year event. The subsequent die-off of trees from the drought released 5 billion tons of CO2. Just five years later another major drought struck. The 2010 drought, which desiccated entire rivers, may have been even worse according to a new study in Science, adding on-the-ground evidence to fears that climate change may inevitably transform the world's greatest rainforest.
Greenland melt is the worst yet
(01/24/2011) Melting of the Greenland ice sheet was the most extreme yet in 2010, beating the previous melt record from 2007. This continues a long-term trend whereby melting in Greenland has increased on average 17,000 square kilometers every year since 1979.
Will Indonesia's big REDD rainforest deal work?
(12/28/2010) Flying in a plane over the Indonesian half of the island of New Guinea, rainforest stretches like a sea of green, broken only by rugged mountain ranges and winding rivers. The broccoli-like canopy shows little sign of human influence. But as you near Jayapura, the provincial capital of Papua, the tree cover becomes patchier—a sign of logging—and red scars from mining appear before giving way to the monotonous dark green of oil palm plantations and finally grasslands and urban areas. The scene is not unique to Indonesian New Guinea; it has been repeated across the world's largest archipelago for decades, partly a consequence of agricultural expansion by small farmers, but increasingly a product of extractive industries, especially the logging, plantation, and mining sectors. Papua, in fact, is Indonesia's last frontier and therefore represents two diverging options for the country's development path: continued deforestation and degradation of forests under a business-as-usual approach or a shift toward a fundamentally different and unproven model based on greater transparency and careful stewardship of its forest resources.
Disappearance of arctic ice could create 'grolar bears', narlugas; trigger biodiversity loss
(12/22/2010) The melting of the Artic Ocean may result in a loss of marine mammal biodiversity, reports a new study published in the journal BNature and conducted jointly by the National Oceanic and Atmospheric Association (NOAA), the University of Alaska, and the University of Massachusetts. The study is the first to project what might happen if species pushed into new habitats because of ice loss hybridize with one another, resulting in such crossbreeds as "narlugas" and "grolar bears".
Top 10 Environmental Stories of 2010
(12/20/2010) Below is a quick review of some of the biggest environmental stories of 2010: Climate change rears it ugly head; Oil spill in the Gulf; Agreement to save global biodiversity; Illegal logging crisis in Madagascar; REDD kicks off in Indonesia; Brazil deforestation falls to its lowest level; Hungary's red sludge; Nestle caves to social media activists; New mammals galore' and Global climate framework back on the table?
Climate change could cut premontane forests of Argentina and Bolivia in half
(12/19/2010) A new study in mongabay.com's open access journal Tropical Conservation Science finds that the premontane forests of Argentina and Bolivia are susceptible to large-scale shifts due to climate change, losing over half of the ecosystem to warmer temperatures. Apart of the Yungas tropical forests, premontane forests are the lowest in the Andes, covering hills and flatland; these forests harbor significant biodiversity, yet many of those species may become threatened as the world warms.
