Melting Arctic sea ice could increase summer rainfall in northwest Europe, study reports
A new study offers an explanation for the extraordinary run of wet summers experienced by Britain and northwest Europe between 2007 and 2012. The study found that loss of Arctic sea ice shifts the jet stream ...
Sandy prompts renewed interest and concern in climate change
Superstorm Sandy's hurricane winds and torrential downpours killed at least 106 people, left millions without power, and caused billions of dollars in damage. It also got people—including the mayor of New ...
Underwater 'tree rings': Calcite crusts of arctic algae record 650 years of sea ice change
Almost 650 years of annual change in sea-ice cover can been seen in the calcite crust growth layers of seafloor algae, says a new study from the University of Toronto Mississauga (UTM).
CryoSat-2 mission reveals major Arctic sea-ice loss
Arctic sea ice volume has declined by 36 per cent in the autumn and 9 per cent in the winter between 2003 and 2012, a UK-led team of scientists has discovered.
Research into carbon storage in Arctic tundra reveals unexpected insight into ecosystem resiliency
When UC Santa Barbara doctoral student Seeta Sistla and her adviser, environmental studies professor Josh Schimel, went north not long ago to study how long-term warming in the Arctic affects carbon storage, ...
Opposite behaviors? Arctic sea ice shrinks, Antarctic grows
The steady and dramatic decline in the sea ice cover of the Arctic Ocean over the last three decades has become a focus of media and public attention. At the opposite end of the Earth, however, something ...
Warmer climate boosts northern crops but the bad soon outweighs the good
Climate change is creating warmer growing conditions in parts of the Earth's northern regions, a new study has found, but experts warn that drought and heat wil soon cancel out the agricultural benefits.
Scientists sound alarm at Arctic Ocean's rapid acidification
Scientists expressed alarm on Monday over the rapid acidification of the Arctic Ocean caused by carbon dioxide emissions, which could have dire consequences on the region's fragile ecosystem.
Unprecedented rate and scale of ocean acidification found in the Arctic
Acidification of the Arctic Ocean is occurring faster than projected according to new findings published in the journal PLoS One. The increase in rate is being blamed on rapidly melting sea ice, a proces ...
Obama's climate strategy falls short: experts (Update)
Environmental groups said Tuesday that US President Barack Obama's plan to combat climate change is long overdue but not enough to reverse a global problem that is outpacing the solutions.
Old permafrost carbon released
Using indicator molecules, a team of researchers headed by ETH Zurich demonstrates that carbon stored in the Arctic permafrost is being mobilised in Eurasian river basins.
Hurricane Sandy: What caused the recent superstorm and how to prepare for the next one
It has been just over a month since Hurricane Sandy devastated the coastal communities of New York and New Jersey, causing billions of dollars in damages and affecting tens of millions of people. According to scientific ...
Climate and land use: Europe's floods raise questions
Less than three months after being battered by snow and ice, central Europe now finds itself fighting floods—and some scientists are pointing the finger at human interference with the climate system.
River ice reveals new twist on Arctic melt
A new study led by Lance Lesack, a Simon Fraser University geographer and Faculty of Environment professor, has discovered unexpected climate-driven changes in the mighty Mackenzie River's ice breakup. This ...
