Decline in snow cover spells trouble for many plants, animals – ‘Snow cover is becoming shorter, thinner, and less predictable. We’re seeing a trend. The subnivium is in retreat.’

By Terry Devitt 6 May 2013 (UW–Madison) – For plants and animals forced to tough out harsh winter weather, the coverlet of snow that blankets the north country is a refuge, a stable beneath-the-snow habitat that gives essential respite from biting winds and subzero temperatures. But in a warming world, winter and spring snow cover […]

World Meteorological Organization confirms 2012 was ninth warmest year on record – ‘The sustained warming of the lower atmosphere is a worrisome sign’

GENEVA, 2 May 2013 (WMO) The World Meteorological Organization’s Statement on the Status of the Global Climate says that 2012 joined the ten previous years as one of the warmest — at ninth place — on record despite the cooling influence of a La Niña episode early in the year. The 2012 global land and […]

Scientists find Antarctic ice is melting faster – Summer ice melt has been 10 times more intense over the past 50 years compared with 600 years ago

By James Grubel; Editing by Paul Tait15 April 2013 CANBERRA (Reuters) – The summer ice melt in parts of Antarctica is at its highest level in 1,000 years, Australian and British researchers reported on Monday, adding new evidence of the impact of global warming on sensitive Antarctic glaciers and ice shelves. Researchers from the Australian […]

Antarctic melt shakes up food chain

By Tim Barlass7 April 2013 (Sydney Morning Herald) – Major changes to the food chain, weather, and landscape of Antarctica have provided stark evidence of the impact of global warming, a report on a polar expedition has revealed. The preliminary report on the research by scientists from the Australian Antarctic Division and the Woods Hole […]

Economist warns millions at risk from climate change – ‘We haven’t been above five degrees Celsius on this planet for about 30 million years. So you can see that this is radical change way outside human experience.’

WASHINGTON, 3 April 2013 (AFP) – The author of an influential 2006 study on climate change warned Tuesday that the world could be headed toward warming even more catastrophic than expected but he voiced hope for political action. Nicholas Stern, the British former chief economist for the World Bank, said that both emissions of greenhouse […]

Marcott, et al., respond to criticisms of their groundbreaking paper that shows 11,000 years of climate change

31 March 2013 (RealClimate) – Readers will be aware of the paper by Shaun Marcott and colleagues, that they published a couple weeks ago in the journal Science. That paper sought to extend the global temperature record back over the entire Holocene period, i.e. just over 11 kyr back time, something that had not really […]

Graph of the Day: Global average surface temperature, 20,000 BC-present, with projection to 2100

[Also see Tamino’s analysis: Global Temperature Change — the Big Picture] By Jos Hagelaars19 March 2013 The big picture (or as some call it: the Wheelchair): Global average temperature since the last ice age (20,000 BC) up to the not-too distant future (2100) under a middle-of-the-road emission scenario. Earlier this month an article was published […]

Inuits worried as they confront new realities of rapidly melting Arctic – ‘The rapidity of the changes has taken us by surprise. We have been underestimating the changes.’

By Meena Menon17 March 2013 OSLO (The Hindu) – The rapid melting of the Arctic sea ice has rejuvenated interests in the region, ranging from oil and gas and mineral exploration to the possibility of shorter sea routes and increased tourism. But all this poses fresh challenges to the survival of the Inuit and other […]

Recent global heat spike unlike anything in 11,000 years – ‘We’ve never seen something this rapid. Even in the ice age the global temperature never changed this quickly.’

By SETH BORENSTEIN8 March 2013 WASHINGTON (AP) – A new study looking at 11,000 years of climate temperatures shows the world in the middle of a dramatic U-turn, lurching from near-record cooling to a heat spike. Research released Thursday in the journal Science uses fossils of tiny marine organisms to reconstruct global temperatures back to […]
