redOrbit Staff & Wire Reports - Your Universe Online An early draft of the forthcoming Intergovernmental Panel on Climate Change (IPCC) has been leaked online by an environmental blogger, despite requests from the UN-body that the contents of the document remain sealed until their official release in 2014. According to Science Recorder reporter Jessica Lear, part of the report was published online by Alec Rawls, a global warming skeptic who created the blog Stop Green Suicide....

Research Shows Sea-Level Rise Is Much Faster Than Previously Reported

Lawrence LeBlond for redOrbit.com - Your Universe Online The Intergovernmental Panel on Climate Change (IPCC) has been keeping a close eye on rising sea levels and has released several reports outlining the forecasts for the future of our world´s oceans. In its fourth assessment report, released in 2007, the IPCC estimated sea levels were rising at a rate of 0.08 inches per year based on satellite data. But new research from the Potsdam Institute for Climate Impact Research, Tempo...

Drought Index Calculations Are Flawed

redOrbit Staff & Wire Reports - Your Universe Online Reports claiming that the climate change has caused global drought conditions to intensify over the past several decades are flawed and based on faulty calculations, according to a new study published Thursday in the journal Nature. According to Anna Salleh of ABC News Australia the researchers report in their study that the 2007 4th Assessment Report (AR4) by the UN Intergovernmental Panel on Climate Change (IPCC) "overestimated"...

High-Pressure Systems To Strengthen
2012-10-06 08:06:14

redOrbit Staff & Wire Reports - Your Universe Online The subtropical highs, or the high-pressure systems over oceans which influence atmospheric circulation and global climate, are expected to become more intense over the next century, according to a new study published online this week in the journal Nature Geoscience. The study, which was led by Duke University assistant professor of earth and ocean sciences Wenhong Li, found that these high-pressure systems, which "largely...

By 2100, global climate change will modify plant communities covering almost half of Earth's land surface and will drive the conversion of nearly 40 percent of land-based ecosystems from one major ecological community type - such as forest, grassland or tundra - toward another, according to a new NASA and university computer modeling study. Researchers from NASA's Jet Propulsion Laboratory and the California Institute of Technology in Pasadena, Calif., investigated how Earth's plant life...

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...

According to MIT researchers, the most recent global climate report fails to capture the reality of the changing Arctic seascape. The researchers said the most recent global climate report fails to capture trends in Arctic sea-ice thinning and drift, and in some cases substantially underestimates these trends.  The Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report estimates that an ice-free Arctic summer by the year 2100. However, Pierre Rampal, a postdoc in...

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...

Many coastal wetlands worldwide "” including several on the U.S. Atlantic coast "” may be more sensitive than previously thought to climate change and sea-level rise projections for the 21st century. U.S. Geological Survey scientists made this conclusion from an international research modeling effort published today in the journal Geophysical Research Letters, a publication of the American Geophysical Union. Scientists identified conditions under which coastal wetlands could...

The French Academy of Science said in a report published Thursday that global warming exists and is unquestionably due to human activity. "Several independent indicators show an increase in global warming from 1975 to 2003. This increase is mainly due to the increase in the concentration of carbon dioxide," the academy said in conclusion to the report. "The increase in carbon dioxide, and to a lesser degree other greenhouse gases, is unquestionably due to human activity," said the report,...
