IPCC 2007 Estimates Of Global Warming Challenged By Scientists
2011-11-25 13:02:28

According to a new study published this week in Science, the rate of global warming from doubling of atmospheric carbon dioxide may be less than previous estimates. The study authors said that global warming is real and that increases of atmospheric CO2 will have multiple serious impacts.  However, the most Draconian projections of temperature increases from the doubling of CO2 are unlikely, which is a projection made by the Intergovernmental Panel on Climate Change (IPCC) in 2007....

Greenhouse Gases Reach Record Highs, WMO Reports
2011-11-22 06:15:52

Carbon dioxide, methane, and nitrous oxide levels reached record highs in 2010, surpassing what experts had previously called the worst-case scenario for these greenhouse gases, the World Meteorological Organization (WMO) announced on Monday. The WMO, which is the U.N.'s weather agency, reported that CO2 levels increased by 2.3 parts per million, to 389 ppm, from 2009 to last year, according to Reuters reporter Tom Miles. That single-year increase exceeds the average for both the 1990s...

Climate Change Has Already Boosted Heat Waves And Rainfall
2011-11-19 06:12:09

According to a report by U.N. scientists, man-made climate change has already boosted heat waves and flood-provoking rainfall and is likely to contribute to future natural disasters. It said that the toll from these extreme weather events will depend as much on the measures taken to protect populations and property as the violence of nature's outbursts. The report is the U.N.'s first comprehensive review of global warming's impact on weather extremes and how best to manage them. "We...

Dr. Kevin Trenberth advocates reversing the 'null hypothesis' The debate may largely be drawn along political lines, but the human role in climate change remains one of the most controversial questions in 21st century science. Writing in WIREs Climate Change Dr Kevin Trenberth, from the National Center for Atmospheric Research, argues that the evidence for anthropogenic climate change is now so clear that the burden of proof should lie with research which seeks to disprove the human role....

Governments around the world must be prepared for mass migrations caused by rising global temperatures or face the possibility of calamitous results, say University of Florida scientists on a research team reporting in the Oct. 28 edition of Science. If global temperatures increase by only a few of degrees by 2100, as predicted by the U.N. Intergovernmental Panel on Climate Change, people around the world will be forced to migrate. But transplanting populations from one location to another...

Clearing The Air On Cloud Simulations
2011-10-27 08:36:16

Climate models have a hard time representing clouds accurately because they lack the spatial resolution necessary to accurately simulate the billowy air masses. But Livermore scientists and international collaborators have developed a new tool that will help scientists better represent the clouds observed in the sky in climate models. Traditionally, observations from satellites infer the properties of clouds from the radiation field (reflection of sunlight back into space, or thermal...

Image 1 - Sea Levels Will Continue To Rise For 500 Years
2011-10-17 08:42:23

Rising sea levels in the coming centuries is perhaps one of the most catastrophic consequences of rising temperatures. Massive economic costs, social consequences and forced migrations could result from global warming. But how frightening of times are we facing? Researchers from the Niels Bohr Institute are part of a team that has calculated the long-term outlook for rising sea levels in relation to the emission of greenhouse gases and pollution of the atmosphere using climate models. The...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
