Himalayas Experiencing Rapid Climate Change

admin — Sat, 19 May 2012 06:20:14 +0000

Average annual mean temperatures in the Himalayas increased 1.5 Celsius or 0.06 Celsius per year between 1982 and 2006, which is three times greater than the average global increase for the same time period, according to new research from the University of Massachusetts, Boston and the Bangalore based Ashoka Trust for Research in Ecology and the Environment (ATREE). The Himalayan

Using Statistical Analysis to Predict Future North American Warming

admin — Thu, 17 May 2012 06:21:31 +0000

I have always been a big fan of statistics, especially after I took that valuable course back in my college days at Rutgers University. I saw this press release from the Ohio State University in regards to statisticians using statistical analysis of different climate models in order to estimate projections of temperature changes and certainty for the years 2021 to

April 2012 Global Surface Temperatures

admin — Tue, 15 May 2012 06:20:43 +0000

April 2012 was tied for 4th warmest on record globally, based on combined land and ocean surface temperature anomalies, according to the Goddard Institute for Space Studies. Monthly temperature anomalies have been slowly increasing since the start of the year. One factor that could be influencing this rebound is the demise of La Nina, which typically has a global cooling

Correction brings Temperature Trend Outlier back in Line

A research group from the University of Washington has identified a problem with one of the three satellite temperature records. The satellite temperature record put out by the University of Alabama at Huntsville (UAH), which is one of three data sets that goes back to 1979 was found to have a data calibration problem. For instance, the UAH lower tropospheric

Global Satellite Temperature Results for April

La Nina is officially done and its global cooling influence also seems to be fading……… Remote Sensing Systems has released their global temperature anomaly data for the lower troposphere as measured by microwave sounding units on board satellites. The RSS image below shows the lower tropospheric temperature anomalies in Celsius for April 2012. April 2012 averaged 0.333 Celsius above normal

Warming Experiments Greatly Underestimate how Plants respond to Climate Change

A group of researchers compared results from controlled environmental warming experiments on plants with massive new archive of historical observations and found that the warming experiments are dramatically underestimating how plants respond to climate change.

Global Mean Sea Level

Global mean sea level has been calculated by satellite measurements since 1993. Several satellites are used in order to determine a mean value. It is clear, the global mean sea level has been rising steadily since 1993. Currently, the annual rise is calculated to be 3.18 mm a year, which is also taking into account the correction for postglacial rebound,

Major Economic Contractions needed to Reduce CO2 Concentrations to Acceptable Levels

Global atmospheric carbon dioxide levels are currently approaching 400 parts per million. As of last week, the actual value from the Mauna Loa Observatory was 396.61 ppm. In order to maintain a safe and stable, global climate, most current research suggests keeping that value somewhere between 300 and 350 ppm. In order to achieve that, recent peer-reviewed research from the

The Eastern U.S. “Warming Hole” of the Late 20th Century

Increased air pollution may have delayed global warming in the eastern U.S. back in the late 20th century. A higher incidence of particulate air pollution (aerosols) in the eastern United States between 1930 and 1990 (peaking around 1980) created a “warming hole” over the eastern United States late in the 20th century.

Arctic Warming

Another indication of climate change is the warming of the Arctic, which as expected has been greater than the rest of the planet. Both surface and satellite measured temperatures clearly show this significant longer-term warming trend in the Arctic. Decreasing sea ice and an increase in soot has reduced the albedo in the Arctic, allowing more of the sun’s energy
