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...

Global Temps Projected To Increase By 2 Degrees

Two research papers, each appearing in the journal Nature Climate Change, have warned that if greenhouse gas emissions continue to increase, global temperatures could exceed “safe” levels of two degrees Celsius in some regions of the world by 2060. Even if the 2C threshold is inevitable, reducing emissions now could delay that rise by up to several decades, giving us much needed time to adapt to climate change. These are the conclusions of new research by scientists from the...

Image 1 - Sea Levels Will Continue To Rise For 500 Years

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...

Climate Change Could Be Causing Plants, Animals To Shrink
2011-10-17 05:18:01

Warmer temperatures and a lack of water are causing some types of plants and animals to become smaller, claims a new study published Monday in the journal Nature Climate Change. According to Marlowe Hood of the AFP, authors Jennifer Sheridan and David Bickford of the National University of Singapore discovered that nearly 45% of the species they studied had decreased in size over the past few generations, and they say climate change is at fault. "The impact of rapidly climbing...

Supercomputer simulations by University of Washington researchers outline the potential risks and benefits of geoengineering Scientists believe that our warming world may face catastrophic changes to its natural environment, including droughts, rising oceans and fiercer, more frequent hurricanes. Theoretically, it may be necessary to act globally to mitigate the damage. Initially, those efforts will probably take the form of limits on greenhouse gas emissions or forest preservation. But...

US and Swiss researchers have, for the first time, modelled a climate system with extremely high carbon emissions in an attempt to test the boundaries of the current computer simulation programs that inform us. Published today, Tuesday 5 July, in IOP Publishing's journal Environmental Research Letters, the study has revealed the potentially devastating effects that high carbon emissions could have on our climate. Little attention has previously been paid to the upper bound range of future...

A United Nations report released Tuesday calls for fast action on reducing emissions of black carbon, ground level ozone and methane to help limit near term global temperature rise preventing the Earth from overheating, reports AFP. Fast action could also reduce losses of mountain glaciers and reduce projected warming in the Arctic over the coming decades by as much as two thirds. Cutting out these pollutants now could also boost global food output and save millions of human lives lost to...

Phil Jones, the United Kingdom scientist who was targeted in the "ClimateGate" affair, now says global warming since 1995 is statistically significant, a year after telling BBC News that post-1995 warming was not significant. He noted that a year worth of data had pushed the trend past the threshold typically used to assess whether trends are in fact "real." Jones said this shows the importance of using longer records for analysis. Scientists generally use a minimum threshold of 95 percent...
