Pasadena, Calif. -- Earth's largest lakes have warmed in the past 25 years in response to climate change, a global survey of temperature trends by U.S. scientists says.
Researchers at NASA's Jet Propulsion Laboratory in Pasadena, Calif., used satellite data to measure the surface temperatures of 167 large lakes worldwide for the comprehensive study, a JPL release said Tuesday.
They found an average warming rate of 0.81 degrees Fahrenheit per decade, with some lakes warming as much as 1.8 degrees per decade.
Although the warming trend was global, the greatest increases were in the mid- to high-latitudes of the Northern Hemisphere, the study found.

Nairobi, Kenya -- Kenya says it is launching Africa's first carbon exchange to facilitate the trading of carbon credits and help tackle climate change.
The market will enable all African countries to sell and trade their carbon credits, the BBC reported Friday.
Carbon dioxide is one of the main gases causing climate change, scientists say, and such exchanges, where polluting industries in rich countries pay for clean development projects in poor countries, are one way to offset carbon emissions.
Experts say Africa will be badly affected by climate change even though most of the greenhouse gases that cause it are produced in the West and Asia.

Madison, Wis. -- As croplands expand at the expense of native ecosystems such as forests, nature loses capacity to protect the world from climate change, U.S. researchers say.
Researchers at the University of Wisconsin-Madison say ecosystems' capacity to store carbon, the element at the heart of global climate problems, is steadily eroding as growing numbers of natural ecosystems give way to agriculture, a university release said Monday.
The effect is most acute in the tropics, where expanding agriculture often comes at the expense of the tropical forests that act as massive carbon sinks because of their rich diversity and abundance of plant life, researchers say.

Newark, Del. -- Increased marine shipping through warming arctic waters could accelerate climate change in the world's northern regions, U.S. and Canadian researchers say.
Scientists say as ice retreats and new shipping lanes open up, ship traffic at the top of the world will increase and with it will come increased air pollution from ship exhaust and other sources, ScienceDaily.com reported Tuesday.
"One of the most potent 'short-lived climate forcers' in diesel emissions is black carbon, or soot," says James J. Corbett, professor of marine science and policy at the University of Delaware.
"Ships operating in or near the arctic use advanced diesel engines that release black carbon into one of the most sensitive regions for climate change," he says.

Leeds, England -- Large-scale crop failures like that which caused the recent Russian wheat crisis are likely to become more common with climate change, a British study shows.
However, researchers at the University of Leeds say improved farming and the development of new crops could lessen the worst impacts of these events on world agriculture, a university release said.
A summer of drought and wildfires dramatically hit harvests across Russia this year, leading the government to institute a ban on wheat exports. But the authors of the new study argue that adaptation to climate change is possible through a combination of new crops that are more tolerant to heat and water stress, and by changes in farming practices and investment.

London -- Birds that migrate over long distances are more vulnerable to climate change than those that make shorter journeys, European researchers say.
Scientists say the increasingly early arrival of spring at breeding sites in Europe makes it harder for birds arriving later from a long flight to attract a mate or find food, the BBC reported.
The researchers warn the "increasing ecological mismatch" can lead to a decline in bird populations.
Earlier this year, U.K researchers published a study that suggested spring was arriving in Britain 11 days earlier than 30 years ago.
"The birds that have not kept track with the changes have declined more in northern Europe," said researcher Nicola Saino of the University of Milan.

Washington -- The world must substantially reduce greenhouse gas emissions if it is to escape the worst impacts of climate change, U.S. and British scientists say.
Climate scientists from both countries reached the conclusion at a meeting in Washington on the United Kingdom's AVOID program, a release from the National Center for Atmospheric Research said Thursday.
The AVOID program is an inter-disciplinary research collaboration across the physical sciences to study climate impacts and the technical and socio-economic implications of climate change, the release said.

Reading, England -- Climate change, expected to increase extreme weather events around the world, will make one particular kind of event rarer, U.K. researchers say.
Scientists at the University of Reading say climate simulations show severe North Atlantic storms known as "polar lows" and resembling arctic hurricanes may decrease by as much as 50 percent by the end of this century, a report in the journal Nature says.
Polar lows are small-scale but severe winter storms that threaten offshore human activities in the North Atlantic region.
Reading researchers Matthias Zahn and Hans von Storch studied the formation of polar lows in a series of regional climate simulations corresponding to different possible future climates.
