In 2009, a controversial scientific experiment dumped 6 metric tons of dissolved iron into the Southern Ocean to see if it would trigger a massive bloom of phytoplankton in iron-deficient…
A new book by Wake Smith, “Pandora’s Toolbox,” explores controversial ideas for artificially cooling the planet. Smith discusses the hopes and hazards of geoengineering in an exclusive Mongabay interview.
Initiatives to inject billions of aerosol particles into the stratosphere to deflect solar rays and cool Earth are too risky to go forward; governments must act fast to rein in potentially disastrous planetary-scale solar geoengineering, say critics.
The normally idyllic resort island of Bali in Indonesia has hogged international headlines since last month, following the eruption of Mount Agung that has driven tens of thousands of residents…
For decades, scientists have been grappling with the consequences of climate change and working toward viable solutions. Climate engineering, also known as geoengineering, is the most controversial possible solution. Currently,…
Geoengineering schemes that aim to slow global warming by seeding oceans with iron to boost carbon dioxide-absorbing phytoplankton may not lead to long-term sequestration of the important greenhouse gas, finds…
Scientists and experts are increasingly concerned that we are entering an age of ecological collapse with untold impacts for future generations. In Daniel Rirdan's new book, The Blueprint, he outlines…
In 1990, British cloud physicist John Latham published a paper arguing he could cool global climate by brightening clouds over the ocean. Most colleagues ignored the paper, titled “Control global…
The ongoing decline in Arctic sea ice hit a new record this year that rocked even the most pessimistic predictions. The low sea ice extent hit 18 percent below the…

Underground storage of carbon dioxide may trigger earthquakes which could allow the gas to seep back into the atmosphere, rendering the emissions mitigation approach ineffective, warns Stanford geophysicist Mark Zoback.…
Efforts to explore geoengineering, whereby governments would employ large-scale projects to alter the world's climate in a bid to combat climate change, received mixed messages this week. In Nagoya, Japan—where…
The idea goes something like this: nations would send megatons of light-scattering aerosol particles into the globe's upper atmosphere, significantly reducing sunlight reaching the earth and thereby immediately cooling the…
Considering it is unlikely that global carbon emissions will start dropping anytime soon, researchers are beginning to look at other methods to combat climate change. One of these is to…
Largely ignored by scientific community, new theory could change how future generations view forests Two Russian scientists, Victor Gorshkov and Anastassia Makarieva of the St. Petersburg Nuclear Physics, have published…
A controversial 'ocean fertilization' experiment suggests seeding the seas with iron to boost carbon-absorbing phytoplantkon will not sequester much carbon dioxide from the atmosphere. Some — including researchers and private…
