Focus On Earth Day 2013, a planetary report card on global warming
Planetary carbon dioxide concentrations are the highest they've been in the past 800,000 years, an ignominious milestone for Earth Day 2013. Still, the world is making some progress toward addressing global warming.

Will we ever understand 2012 drought? Study blames 'random weather' (+video)
The drought of 2012 was more about unusual weather patterns than global warming, says a study. But its authors acknowledge the record-smashing event likely will be a puzzle for years to come.
-
Global temperature rise is fastest in at least 11,000 years, study says
The study, which also found the magnitude of the global temperature rise to be unmatched in 4,000 years, suggests that the current warming trend cannot be explained by naturally occurring temperature fluctuations.

Sardines in India latest indicator of how your food is on the move
Mumbai’s new sardine bounty is an example of how warmer temperatures may be redrawing the world’s geographic distribution of food with potential implications for what and how we eat.

Are human-caused and natural global warming different? Study says yes.
A study suggests that human-caused and natural global warming episodes affect rainfall rates differently. The finding could help scientists better forecast what's ahead.

Global water crisis: Seen from the first Himalayan glacial trickle
Global water crisis: Reporter William Wheeler talks about water stress from the effects of climate change high in the Himalayas where India and Pakistan's great rivers start to Haiti's fresh-water pollution.

Cover Story Global water crisis: too little, too much, or lack of a plan?
The global water crisis – caused by drought, flood, and climate change – is less about supply than it is about recognizing water's true value, using it efficiently, and planning for a different future, say experts.

Polar ice melt accelerates (+video)
The Earth's ice sheets are melting three times faster than they were two decades ago, 47 researchers say in a recently published study. The scientists fault human-created global warming for the dramatic increase in melting.

Are polar ice sheets shrinking? Report offers definitive answer at last.
Numerous studies in recent years have offered different – and sometimes conflicting – views about ice sheets in Greenland and Antarctica. But a new report offers unprecedented scope.

World Bank: Tackle warming or poverty remains
Climate change will hit all nations, but especially the poor ones, says new World Bank report. Warming could flood Vietnam and Bangladesh, dry out other areas, causing water scarcity.
-
How reliable are drought predictions? Study finds flaw in popular tool.
Researchers say the Palmer Drought Severity Index, devised for monitoring short-term trends, has been misused for longer term analyses and is thrown off by higher temperatures from global warming.

As Antarctic ice streams speed up, major ice melt triggered inland
New simulation results may also add to forecasts about Antarctica's contribution to global sea levels, researchers pointed out.

Arctic ice to reach record lows, say scientists
Sea ice in the Arctic Ocean is likely to hit record lows next week, and then keep on melting, according to the US National Snow and Ice Data Center.
-
Focus Weather? Climate change? Why the drought is persisting and growing.
Several factors, including La Niña events, have contributed to the expanded drought, meteorologists say. Conditions in the West may be setting up for a 'megadrought' by century's end, researchers warn.

Prominent climate change denier now admits he was wrong (+video)
Richard Muller, who directed a Koch-funded climate change project, has undergone a 'total turnaround' on his stance on global warming, which he now admits is caused by human activity.
-
Humongous hidden Antarctic rift could be speeding ice melt, say scientists (+video)
A huge newly discovered rift, buried a mile beneath the ice in Antarctica, could be contributing to ice loss, according to researchers.
-
Sudden Greenland ice sheet melt baffles scientists (+video)
Satellite images have shown melting over 97 percent of the surface of Greenland's ice sheet in just four days, an event thought to occur every 150 years on average.

Colorado wildfires are 'what global warming really looks like' (+video)
The wildfires ravaging Colorado are a preview of the kinds of disasters that human-caused climate change could bring about, say scientists.

West Coast sea levels: New report estimates greater rise by 2100
The estimates from the National Research Council, taking advantage of more recent research, range from 19 to 55 inches. The study is expected to become a common frame of reference that coastal communities can use in planning.

Climate change: Arctic passes 400 parts per million milestone
Arctic monitoring stations show carbon dioxide levels are now above 400 parts per million. Carbon dioxide is the chief climate-change gas and stays in the atmosphere for 100 years. Before the Industrial Age, carbon dioxide levels were 275 ppm.

Warm water threatens vast Anatarctic ice shelf (+video)
A new study indicates that a large ice sheet is at risk. Warm water from below is causing it to melt.

Troublesome Karakoram glaciers getting bigger, new study suggests
Despite the global temperature increase and the overall shrinking of the world's glaciers, some glaciers in the Karakoram mountains have actually grown over the past decade, according to a new study.
