Time running out to reach 2 C warming target: UN experts
Time is running out to limit global warming to two degrees Celsius (3.6 degrees Fahrenheit), the United Nations' climate experts said Sunday, warning that current trends in carbon emissions will lead to disaster.
How global warming works, in 35 words, or 52 seconds
Earth transforms sunlight's visible light energy into infrared light energy, which leaves Earth slowly because it is absorbed by greenhouse gases. When people produce greenhouse gases, energy leaves Earth even more slowly ...
Future warming likely to be on high side of climate projections, research finds
Climate model projections showing a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise, according to a new analysis by scientists at the National Center ...
World set to heat up despite clean-energy efforts, IEA warns
Global warming is set to heat up with temperatures rising to nearly twice targets set by the United Nations, the International Energy Agency warned on Tuesday.
Minimum CO2 price of $32 needed to curb warming, study shows
A global carbon price of at least $32 (24 euros) per tonne is needed by 2015 to apply an effective brake on global warming—almost five times today's European market rate, a study said Monday.
In prehistory, CO2 and warming went in lock-step
Levels of carbon dioxide rose hand-in-hand with warming at the end of the last Ice Age, according to a study Thursday that deals a blow to climate skeptics.
Greenhouse gas levels in atmosphere hit new high, UN reports
Surging levels of carbon dioxide sent greenhouse gases in the atmosphere to a new record in 2013, while oceans, which absorb the emissions, have become more acidic than ever, the UN said on Tuesday.
Study reveals seasonal patterns of tropical rainfall changes from global warming
Projections of rainfall changes from global warming have been very uncertain because scientists could not determine how two different mechanisms will impact rainfall. The two mechanisms turn out to complement ...
Disappearing snow increases risk of collapsing ice shelves in Antarctica
A number of floating ice shelves in Antarctica are at risk of disappearing entirely in the next 200 years, as global warming reduces their snow cover. Their collapse would enhance the discharge of ice into ...
Temperatures to rise 0.3-4.8 C this century, UN panel says
A UN panel said Friday it was more certain than ever that humans were causing global warming and predicted temperatures would rise by 0.3 to 4.8 degrees Celsius (0.5-8.6 degrees Fahrenheit) this century.
UN document warning of grave climate future completed
Leading scientists and officials completed a fresh climate report Sunday expected to lay bare the grim impact of climate change, with warnings that global food shortages could spark violence in vulnerable ...
Climate warnings ignored with US elections looming
The U.S. Congress, ignoring dire new warnings about climate change, continues to shy away from legislation that might mitigate the effects of global warming, leaving President Barack Obama with limited tools to reduce greenhouse ...
Study links changing winds to warming in Pacific
A new study released Monday found that warming temperatures in Pacific Ocean waters off the coast of North America over the past century closely followed natural changes in the wind, not increases in greenhouse ...
Ocean winds keep Antarctica cold, Australia dry
New Australian National University-led research has explained why Antarctica is not warming as much as other continents, and why southern Australia is recording more droughts.
