The greenhouse gases humans have released into the atmosphere over the past 100 to 150 years, mostly in the form of carbon dioxide, have led to a 1.1° Celsius (2°…

The push to halt climate change too often neglects the interconnected issue of biodiversity loss, according to a recent report from a panel of scientists with the United Nations. “What…

Vast terrains dominated by grasses, shrubs or sparse trees, rangelands are more than unproductive places where reticent herders graze their livestock and wildlife browse dry — or green, if lucky…

Created in 1987, the pathbreaking treaty not only phased down scores of ozone depleting chemicals and is helping heal the ozone hole — it also offers a flexible, regularly updating example for future environmental treaties.

Some 100 ozone-depleting CFCs and HCFCs are being phased out by the landmark treaty, but can this evolving accord now save Earth from the HFCs — one of which is a greenhouse gas 12,700 more potent than carbon dioxide.

More numerous than stars, our planet’s microbes play an integral role in helping life thrive on Earth. But what happens when climate change, pollution and ocean acidification impact microbes? — We don’t know.

The Earth is a huge floating mass of rock, liquid and gas, weighing a staggering 5.9 sextillion tons. But there’s only one part that supports life: the biosphere, a thin…

Today we discuss Planetary Boundaries, nine environmental systems identified by scientists as essential to Earth’s ability to sustain life and the limits to how far out of equilibrium we can…

More than a decade after the Planetary Boundaries framework was first proposed by top scientists, we are no closer to changing our destructive trajectory — but 2021 gives us three opportunities to act.

The world’s leaders, private companies and individuals must take a coordinated approach to address three environmental calamities facing the Earth at this moment, according to a report released Feb. 18…

Avoiding the loss of human life and the economic fallout caused by future pandemics will require a seismic change in our approach to the causes of the emergence of disease-causing…

Shifting rainfall patterns, especially those exacerbated by climate change, could drive large parts of the Amazon rainforest to become drier savanna, a new study has found. Rainfall acts like a…

The new Science Panel for the Amazon — modeled on the UN Intergovernmental Panel on Climate Change — aims to consolidate knowledge on the Amazon rainforest and guide future public policies to conserve it.

April and May saw record intense Arctic heat. Now some scientists are asking whether an absence of industrial sulfate aerosol pollutants, which reflect solar energy, could be the cause.

Multiple studies show that Arctic warming is altering temperate and equatorial weather. Now, new research finds that Antarctic ice melt could be a major tropical change agent too.

New research offers early evidence that the Arctic and tropics are no longer a world apart; melting sea ice may be intensifying equatorial trade winds and emergence of El Niño.

Grappling with the challenges of minimizing carbon footprints, memoirs of careers spent on the frontlines of conservation and stark warnings about the future inhabitability of our world, the roster of…

The burning of vegetation and the release of climate-warming gases into the atmosphere are conspiring to dry out the Amazon rainforest, according to a new study. “We observed that in…

Chilean President Sebastián Piñera announced on Oct. 30 that his country was cancelling the 25th annual United Nations climate conference due to the social crisis that has swept the country…

Overhauling how humans manage Earth’s surface could account for the equivalent of 15 billion metric tons (16.5 billion tons) of CO2 every year through a combination of lower emissions and…

Cataloging the growing number of declining species or tracking the relentless rise of temperatures around the world today can make for some dark days for scientists in these areas of…

As 2019 melt season nears end, 40 years of satellite data reveal a rapidly warming polar region, with no end in sight, plus multiple impacts for a changing planet. This story has been updated.

High heat and conditioning throughout this year’s melt season put a hurting on Arctic sea ice, but it may still take big storms or more heat to break 2012 extent record.

How we use the planet’s land, including forests, will make a huge difference in determining the path of climate change in the future, according to the Intergovernmental Panel on Climate…

After two years of severe drought, lacking electricity and water, with a $500 annual budget, the Botanical Garden of Caracas struggles valiantly to protect its precious collection.

A very hot Arctic spring has caused sea ice volume to fall rapidly to a new record, putting 2019 in position to challenge 2012 for lowest ice volume and extent this September.

Though the trend can still change, Arctic sea ice extent could be on track for a record melt year, impacting the jet stream and bringing more extreme weather to the U.S. and world.

Deforestation can reduce communities’ access to clean drinking water, according to a recent study conducted in Malawi. A lot of prior research on how deforestation impacts water dynamics has shown…

Sea ice melt is nearly two weeks ahead of past records for early April, while a new study finds that the Arctic system is trending away from its 20th century state into an unprecedented state.

The chief minister of the Malaysian state of Sabah has called on construction crews working on the multi-billion-dollar Pan Borneo Highway project to avoid breaking up the region’s forests and…
