‘Conservative’ study warns climate change may kill half of Earth’s plant life

More than half of common species of plants and a third of animal species are likely to see their living space halved by 2080 on current trends of carbon emissions, a climate study said on Sunday. Output of man-made greenhouse gases is putting Earth on track for four degrees Celsius…

Scientists slam Canada’s tar sands production: Doesn’t address climate change in ‘meaningful way’

Letter urges natural resources minister Joe Oliver to consider consequences of his support for controversial policy The Canadian government’s promotion of the tar sands industry is setting the world on a course of catastrophic climate change, a group of climate scientists and economists have warned. In a letter made available…

Study finds belief in free market economics predicts rejection of science

A strong belief in a hands off approach to economics is tightly linked to the rejection of scientific facts such as climate change, according to research published in Psychological Science in late March. “The conspiracist ideation that all of the world’s scientific academies have conspired together to create a hoax…

Antarctic ice tells conflicting story about climate change’s role in big melt

Since the early 1990s, glaciers draining Antarctica’s vast ice sheets have…  …

Climate change pits pandas against pinot

Which is more important, pandas or pinot? Researchers say that is a question conservationists and wine-growers will have to answer in the coming years as climate change sparks a hunt for cooler places to grow wine grapes, even if those places are home to sensitive animal populations. Already, big players…

Climate change pioneer James Hansen to retire

Pioneering NASA climatologist James Hansen, one of the first scientists to raise the alarm about global warming, is retiring after 46 years, a colleague confirmed to AFP on Tuesday. Hansen, 72, who headed the Goddard Institute for Space Studies in New York, announced his departure in an email to the…

Climate change models predict remarkably accurate results

By Duncan Clark, The Guardian Analysis of climate change modelling for past 15 years reveal accurate forecasts of rising global temperatures Forecasts of global temperature rises over the past 15 years have proved remarkably accurate, new analysis of scientists’ modelling of climate change shows. The debate around the accuracy of…

NOAA: 2012 saw second largest rise in climate emissions on record

Heat-trapping carbon emissions in the atmosphere grew so much in 2012 that the year will go down as the second-highest growth in recorded history, placing the globe dangerously near a climatic tipping point, scientists with the National Oceanic and Atmospheric Administration said Tuesday. Climate-causing emissions measured 48 times last year…

Environmentalists plan massive rally to spur action on climate change

Activists are stepping up pressure on US President Barack Obama to issue concrete plans to battle climate change, with a major rally planned in Washington following his annual address to Congress. More than 100 groups are planning what they hope will be the largest rally in the United States on…

Cities affect weather thousands of kilometers away: study

Heat from large cities alters local streams of high-altitude winds, potentially affecting weather in locations thousands of kilometres (miles) away, researchers said on Sunday. The findings could explain a long-running puzzle in climate change — why some regions in the northern hemisphere are strangely experiencing warmer winters than computer models…
