Global Warming intensifying Global Water Cycle by double current climate model projections

New research into ocean salinity levels has revealed a strong global water cycle intensification during the period of 1950 to 2000. The researchers report the rate of change in the global water cycle is double the rate projected by current-generation climate models. The study found "robust evidence of an intensified global water cycle at a rate of about eight per cent per degree of surface

Pollution caused global warming hole delayed climate change over eastern United States


Reduction in air pollution from coal fired power stations due to environmental regulations since the 1980s has increased regional global warming in the Central and Eastern United States. Climate scientists from the Harvard School of Engineering and Applied Sciences (SEAS) found that particulate pollution, particularly from coal fired power stations, caused a global warming hole, or a large cold

New Breakthrough in Photovoltaic solar cell efficiency

Researchers from Helmholtz Centre Berlin for Materials and Energy and the University of Sydney, with Australian Solar Institute support, have achieved a record breaking 40 per cent efficiency in the output from crystalline silicon solar cells. Previously, only up to about 33 per cent of energy could be harvested from normal amorphous crystalline silicon solar cells.

Global Warming threshold for Greenland Ice Sheet collapse reduced to 1.6 degrees C


New research from the Potsdam Institute for Climate Impact Research and Universidad Complutense de Madrid has lowered the best estimate for the irreversible collapse of the Greenland Ice Sheet down to 1.6 °C, making the ice sheet more vulnerable than previously thought to global warming. The previous best estimate was 3.1 °C. As we currently have 0.8 °C of global warming, by the middle of the

Global Warming means 20 Metre sea level rise in the pipeline say scientists

Scientists studying the geological record have determined that at slightly above current temperatures we are about 20 metres below what the sea level equilibrium should be. Sea levels are increasing and forecast to rise at least a metre this century (although there is a low probability they could be higher than this), much of the change in sea level will occur over several hundred or thousands of

Carnaby's Cockatoo suffers 37 per cent population decline in one year

Flocks of Carnaby's Black Cockatoo are iconic sights for the people of Perth, the Swan River Region and the forests of the South west. But comparing two population surveys in 2010 and 2011 showed a 37 percent decline in numbers across the Swan river region. That is a 37 per cent decline in one year.
According to Statistical modelling based on the 2011 Great Cocky Count the population of Carnaby’s

Ocean acidification increasing at unprecedented rate not seen in last 300 million years


In a new study marine scientists warn that the rate of ocean acidification presently occurring is unprecedented in the last 300 million years. This is due to dissolving carbon dioxide from the atmosphere, much of which human activity has contributed over the last 200 years through the use of fossil fuels. The extent of the acidification and rate of acidification enhances the prospect for a mass
