"Epidemiological" Study Demonstrates Climate Change Effects On Forests

An 18-year study of 27,000 individual trees by National Science Foundation (NSF)-funded scientists finds that tree growth and fecundity - the ability to produce viable seeds - are more sensitive to climate change than previously thought. The results, published Global

Arctic Ocean freshwater will cause 'unpredictable changes on climate'

A vast expanse of freshwater in the midst of the Arctic Ocean is set to wreak unpredictable changes on the climate in Europe and North America, new scientific analysis has shown.The water – comprising meltwater from the ice cap and run off from rivers – is at

Record depletion of Arctic ozone layer causing increased UV radiation in Scandinavia

Over the past few days ozone-depleted air masses extended from the north pole to southern Scandinavia leading to higher than normal levels of ultraviolet (UV) radiation during sunny days in southern Finland. These air masses will move east over the next few days,

Wind and waves growing across the globe

The world has gotten stormier over the past two decades - and the reason is a mystery, a new study says. In the past 20 years, winds have picked up around 5 percent on average.Extremely strong winds caused by storms have increased even faster, jumping 10 percent over 20

NASA Satellites Detect Extensive Drought Impact On Amazon Forests

Last year record-breaking drought caused widespread reductions in the greenness of Amazon forests. A new  NASA-based study has revealed that the level of Amazonian vegetation decreased dramatically over an area more than three and one-half times the size of Texas. It

Boreal Forest

Russian boreal forests undergoing vegetation change

Russia's boreal forest - the largest continuous expanse of forest in the world, found in the country's cold northern regions - is undergoing an accelerating large-scale shift in vegetation types as a result of globally and regionally warming climate.That in turn is

Eddy in the Gulf Stream C 007

Will the Gulf Stream slow down?

The Gulf Stream and North Atlantic Drift – which are part of the Atlantic thermohaline circulation – bring warm water, and with it warm air, from the tropical Atlantic to northern Europe. This helps keep Europe several degrees warmer than it would otherwise

Deadly heatwaves will be more frequent in coming decades

A new study warns that 'mega-heatwaves' like the one estimated to have killed tens of thousands in western Europe in 2003 will become up to 10 times more likely over the next 40 years. The new analysis revealed that heatwave that scorched eastern Europe in 2010,

About geomagnetic reversal and poleshift

A growing number of scientists are starting to worry the magnetic pole shift, that seems to be underway, is the real culprit behind climate change. Not man made air pollution, not the Sun, not the underground volcanic activity heating up the oceans, but the slow beginni

Groundwater vanishing in Central Valley

Over-pumping is pulling vast and unsustainable amounts of groundwater from the heart of California farming, the Central Valley, a new UC Irvine satellite study shows – with enough lost over four years to fill two-thirds of Lake Mead. The phenomenon shows no...
