Neotropical cloud forests to lose what most defines them: Clouds

In as few as 25 years, climate change could shrink and dry 60-80% of Western Hemisphere cloud forests, finds a study published today. If greenhouse gas emissions continue increasing as they have been, 90% of Western Hemisphere cloud forests would be affected as early as 2060. »

Climate change to blame for Hurricane Maria's extreme rainfall

Hurricane Maria dropped more rain on Puerto Rico than any storm to hit the island since 1956, a feat due mostly to the effects of human-caused climate warming, new research finds. »

What Earth's gravity reveals about climate change

On March 17, 2002, the satellite duo GRACE was launched to map the Earth's gravity field more precisely than ever before. The measurements make it possible to monitor the terrestrial water cycle, the mass balance of ice sheets and glaciers or changes in sea levels. This helps to better understand important trends in the global climate system. »

How inland waters 'breathe' carbon -- and what it means for global systems

A new study reveals important insights into the factors that influence the release of greenhouse gases from rivers and streams, including a key relationship between storm events, ecology, and topography in moderating this release. »

Plastic's carbon footprint

From campaigns against microplastics to news of the great Pacific garbage patch, public awareness is growing about the outsized effect plastic has on the world's oceans. However, its effect on the air is far less obvious. Plastic production, use, and disposal all emit prodigious amounts of greenhouse gasses, but scientists haven't had a firm grasp on the scope. »

Warming Arctic permafrost releasing large amounts of potent greenhouse gas

A recent study shows that nitrous oxide emissions from thawing Alaskan permafrost are about twelve times higher than previously assumed. About one fourth of the Northern Hemisphere is covered in permafrost, which is thawing at an increasing rate. As temperatures increase, the peat releases more and more greenhouse gases. »

Electric vehicle adoption improves air quality and climate outlook

A new study quantified the differences in air pollution generated from battery-powered electric vehicles versus internal combustion engines. The researchers found that even when their electricity is generated from combustion sources, electric vehicles have a net positive impact on air quality and climate change. »

Yukon warmest it has been in 13,600 years

A study uses new research techniques to reveal alarming information about climate change in Canada's north. A study confirms that recent climate warming in the central Yukon region has surpassed the warmest temperatures experienced in the previous 13,600 years, a finding that could have important implications in the context of current global warming trends. »

Reducing greenhouse gases while balancing demand for meat

Humans' love for meat could be hurting the planet. Many of the steps involved in the meat supply chain result in greenhouse gas emissions. But a new international study evaluates several strategies that could reduce these environmental effects. »

Biodiversity: Climate key to abundance of life

Natural history museum paleontologists have succeeded in mapping historical biodiversity in unprecedented detail. For the first time, it is now possible to compare the impact of climate on global biodiversity in the distant past -- a result that paints a gloomy picture for the preservation of present-day species richness. »

Genetic breakthrough on tropical grass could help develop climate-friendly cattle farms

Researchers have shown that Brachiaria grass species can reduce greenhouse gas emissions from cattle and increase productivity -- and breeding improved varieties can potentially augment the environmental and economic benefits. »

Renewables are a better investment than carbon capture for tackling climate change

Solar panels and wind turbines coupled with energy storage offer a better hope for tackling climate change than trying to capture carbon from fossil fuel power stations, according to new research. »

Climate change impacts peatland CO2 gas exchange primarily via moisture conditions

A new study suggests that peatland CO2 exchange is more strongly influenced by drying than warming as such, and that soil moisture may be critical to determining whether fen ecosystems are able to adapt to a changing climate. »

Climate panel disbanded by Trump, now regrouped, releases its report

A federal advisory committee started meeting in 2016 to explore how to make the National Climate Assessment more usable for communities who want to take action. President Trump dismissed the panel in 2017. But with support from the Earth Institute at Columbia University, New York state and the American Meteorological Society, the committee reconvened. »

Be the change you want to see in the world

Individuals have as big a role to play in tackling climate change as major corporations but only if they can be encouraged to make significant lifestyle changes by effective government policy, a major new European study has found. »

Permian volcanism contributed to atmospheric greenhouse gas content in Antarctica

The Choiyoi magmatic Province, with an estimated volume of ~1.3 million square kilometers, represents a voluminous Permian subduction-related volcanic episode that has thus far been described only from South America. Geologists have investigated Permian volcaniclastic rocks from central Antarctica to determine the potential magmatic source of volcanic detritus in southwestern Gondwana. »

A slippery slope: How climate change is reshaping the Arctic landscape

Increasing ground temperatures in the Arctic are indicators of global climate change, but until recently, areas of cold permafrost were thought to be relatively immune to severe impacts. A new study, however, shows that areas of cold permafrost can be vulnerable to rising summer temperatures. »

Restore natural forests to meet global climate goals

International plans to restore forests to combat global warming are flawed and will fall far short of meeting 1.5C climate targets, according to new research. »

Natural climate processes overshadow recent human-induced Walker circulation trends

A new study shows that the recent intensification of the equatorial Pacific wind system, known as Walker Circulation, is unrelated to human influences and can be explained by natural processes. »
