Climate change could bring stronger winds, more wind power

A new study by the British Antarctic Survey, the University of Oxford and the University of Bristol looked at what effect a warmer world would have on winds, specifically across the UK and Northern Europe where wind power is already becoming a major source of energy. In a world that is on average 1.5 degrees Celsius warmer, winds would be stronger and as a result, wind power would make up a significantly larger chunk of the electricity produced in that part of the world.
A warmer world brings with it more wind.
Using data from 282 onshore wind turbines over a span of 11 years paired with climate model data for that 1.5 degree increase in global temperature, the researchers found that in the UK alone there could be a 10 percent increase in wind energy generation. That's equivalent to meeting the energy demands of an additional 700,000 homes based on the current wind power capacity. The UK is quickly increases wind power installations, so that number would likely be even higher in the future.

Germany, Poland and Lithuania would also see major gains in wind energy production, but the UK stood out from the rest.

Sudden ice loss from previously stable region of Antarctica


A

 group of scientists, led by a team from the University of Bristol, UK has observed a sudden increase of ice loss in a previously stable region of Antarctica.

A story published today by Science Daily says, “Using measurements of the elevation of the Antarctic ice sheet made by a suite of satellites, the researchers found that the Southern Antarctic Peninsula showed no signs of change up to 2009.

“Around 2009, multiple glaciers along a vast coastal expanse, measuring some 750km in length, suddenly started to shed ice into the ocean at a nearly constant rate of 60 cubic km, or about 55 trillion litres of water, each year.

“This makes the region the second largest contributor to sea level rise in Antarctica and the ice loss shows no sign of waning.”
