Wind electricity to be fully competitive with natural gas by 2016
So says Stephen Lacey at Climate Progress:
The best wind farms in the world are already competitive with coal, gas and nuclear plants. But over the next five years, continued performance improvements and cost reductions will bring the average onshore wind plant in line with cheap natural gas, even without a price on carbon.
That’s according to Bloomberg New Energy Finance. They say that cost reduces by 7% for every doubling of installed capacity, while efficiency has steadily improved. Continue reading Climate clippings 54
Greenland ice loss
The rate continues to accelerate, according to Skeptical Science.
It looks ugly, but see comment 24 and the correction @ 27. Doubling the rate each decade will give you 3,200 gt each year by 2050. But that’s still only a bit less than 9mm pa of sea level rise, according to my calculations. Concerning, certainly, but not yet catastrophic. Continue reading Climate clippings 48
According to Oxfam 21,000 people died due to weather-related disasters in the first nine months of 2010 – more than twice the number (10,000) for the whole of 2009. Their information comes from reinsurance company Munich Re.
The number of extreme weather events was 725 to September, as against 850 for 2009. The number of extreme events is likely to exceed the ten-year average of 770, but not by a large margin. This year included some particularly serious ones, such as the floods in Pakistan and the heatwave in Russia.
The Pakistan floods affected more than 20 million people, submerging about a fifth of the country, claiming 2,000 lives and causing $9.7 billion in damage. Summer temperatures in Russia exceeded the long-term average by 7.8°C, doubling the daily death rate in Moscow to 700 and causing fires that destroyed 26 per cent of the country’s wheat crop. Russia banned grain exports as a result and soon after world grain prices increased, affecting poor people particularly.
Statistics relating to extreme weather events are tricky. The number of deaths obviously relates to the severity of the individual events and how many people were living in areas where the events occurred and hence vulnerable. Continue reading Climate kills
