Tiny marine creature spreading through ocean, stabilizing reefs and islands with calcareous shells
The climate is getting warmer, and sea levels are rising -- a threat to island nations. As a group of researchers found out, at the same time, tiny single-cell organisms are spreading rapidly through the world's oceans, where they might be able to mitigate the consequences of climate change. Amphistegina are stabilizing coastlines and reefs with their calcareous shells. »Predicting a low carbon future for Toronto
Cities are major players in the climate change game. More than half of the world's population lives in urban areas and over 70 percent of global GHG (greenhouse gas) emissions can be attributed to cities. A case study of Toronto demonstrates alternative strategies for how the city can implement a low carbon urban infrastructure plan by 2031. »Lungs of the planet reveal their true sensitivity to global warming
The amount of carbon dioxide that rainforests absorb, or produce, varies hugely with year-to-year variations in the climate. Climate scientists have shown that these variations reveal how vulnerable the rainforest is to climate change. »Climate change clues from tiny marine algae -- ancient and modern
Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago. The study found that their response to environmental change varies between species, in terms of how quickly they grow. »Ozone depletion trumps greenhouse gas increase in jet-stream shift
Depletion of Antarctic ozone is a more important factor than increasing greenhouse gases in shifting the Southern Hemisphere jet stream in a southward direction, according to researchers. »New research shows complexity of global warming
Global warming from greenhouse gases affects rainfall patterns in the world differently than that from solar heating, according to a new study. »Climate change could cause massive losses in Pyrenees ski resorts
An increase in temperatures due to climate change could mean that the Andorran ski resorts have a shorter season in the future, especially in lower areas. An increase of 4 ºC would stop the artificial snow machines from maintaining the ski season in the lowest areas. »New Greenland ice core reveals warmer temperatures 120,000 years ago
A new study provides surprising details on changes in Earth’s climate during the last warm period (120,000-128,000 years ago). Even though temperatures in Northern Greenland were 5-8 degrees Celsius higher than today, the thickness of the ice sheet was only a few hundred meters lower. And this despite the fact that sea level was 4-8 metres higher than today. »Unprecedented glacier melting in the Andes blamed on climate change
Glaciers in the tropical Andes have been retreating at increasing rate since the 1970s, scientists write in the most comprehensive review to date of Andean glacier observations. The researchers blame the melting on rising temperatures as the region has warmed about 0.7°C over the past 50 years (1950-1994). »NASA ozone study may benefit air standards, climate
A new NASA-led study finds that when it comes to combating global warming caused by emissions of ozone-forming chemicals, location matters. »Climate change's effects on temperate rain forests surprisingly complex
Longer, warmer growing seasons associated with a changing climate are altering growing conditions in temperate rain forests, but not all plant species will be negatively affected, according to new research. »New insights on drought predictions in East Africa
New research helps explain the mechanisms at work behind historical patterns of aridity in Eastern Africa over many decades -- findings that may help improve future predictions of drought and food security in the region. »Heat waves, storms, flooding: Climate change to profoundly affect Midwest, U.S. in coming decades
In the coming decades, climate change will lead to more frequent and more intense Midwest heat waves while degrading air and water quality and threatening public health. Intense rainstorms and floods will become more common, and existing risks to the Great Lakes will be exacerbated. »New Antarctic geological timeline aids future sea-level predictions
Radiocarbon dates of tiny fossilized marine animals found in Antarctica's seabed sediments offer new clues about the recent rapid ice loss from the West Antarctic Ice Sheet and help scientists make better predictions about future sea-level rise. This region of the icy continent is thought to be vulnerable to regional climate warming and changes in ocean circulation. »Global warming may have severe consequences for rare Haleakalā silversword plants
While the iconic Haleakala silversword plant made a strong recovery from early 20th-century threats, it has now entered a period of substantial climate-related decline. New research warns that global warming may have severe consequences for the silversword in its native habitat. »Where there's smoke or smog, there's climate change
In addition to causing smoggy skies and chronic coughs, soot – or black carbon – is the number two contributor to global warming. »Information required for short-term water management decisions outlined
Adapting to future climate change impacts requires capabilities in hydroclimate monitoring, short-term prediction and application of such information to support contemporary water management decisions. A new report provides details. »Heat-resistant corals provide clues to climate change survival
In a future shaped by climate change, only the strong -- or heat-resistant -- will survive. A new study opens a window into a genetic process that allows some corals to withstand unusually high temperatures and may hold a key to species survival for organisms around the world. »Future sea level rise from melting ice sheets may be substantially greater than IPCC estimates
Future sea level rise due to the melting of the Greenland and Antarctic ice sheets could be substantially larger than estimated in Climate Change 2007, the Fourth Assessment Report of the IPCC, according to new research. »Under the weather, literally: More rainfall and bigger storms may lead to more stomach upsets
We can blame all sorts of things on the weather. But a stomach bug? It seems unlikely. Yet, scientists say greater quantities of rainfall and bigger storms will lead to more stomach upsets in parts of Europe. »Most popular
20 May, 01:10, reuters - Extreme global warming is less likely in coming decades after a slowdown in the pace of temperature rises so far this century, an international team of scientists said on Sunday. More »
20 May, 19:31, guardian - Wouldn't it be nice to live in a world where armchair experts gave up fighting over whether climate change is occurring? This spring, I began receiving calls and emails from colleagues about a strange little book that was mailed to environmental science professors around the country. This was a big mailing, in total, a reported 100,000 copies were sent out. More »

23 May, 10:50, guardian - Committee on Climate Change says the sooner the UK invests in low-carbon power generation the cheaper it will be. Investing in new renewable power generation, rather than a "dash for gas", will be the lower-cost option for keeping the lights on while cutting greenhouse gas emissions, the government's climate change watchdog has said.
