Well, hotter than normal.
That is the temperature for Wednesday 17 February, referenced to a 1979-2000 base, from John Englander’s blog.
Some parts of the planet’s surface are 15 – 20 degrees Celsius colder than we would expect, and other parts are 15 – 20 degrees Celsius warmer.
However, with climate change one of the big effects is destabilisation of the weather. Continue reading Texas is freezing, but the Arctic is hot
Well, not everywhere, it’s dry here this winter, but definitely in Texas, and in India, Nepal, Bangladesh and now Pakistan. In fact, in the Indian subcontinent more than 1,400 people are dead since the recent rains started, and more than 45 million are directly affected, many having had their livelihoods destroyed. Mumbai, a city of some 20 million people, had a month’s rain in a single day. Two-thirds of Bangladesh was said to be under water. Here’s an early map from August 29:
These posts include a brief mention of a number of news items relating to climate change. They don’t preclude treating any of these topics at more length in a separate post.
They can also serve as an open thread so that we can keep each other informed on important climate news.
Mega-heatwaves in Europe
Mega-heatwaves like the one in 2003 will become five to 10 times more likely by 2050 according to a recent study, occurring at least once a decade. The 2010 heatwave was something else again.
But the 2010 heatwave was so extreme – 10C above the average for the first week of August between 1970 and 2000 – that similar events are only expected to occur once every 30 years or so.
The 2010 event caused some 50,000 deaths, reduced the Russian grain crop by 25% and cost the nation $15 billion. It should be noted that the link between that event and climate change as such has not yet been established, but the incidence of mega-droughts is expected to increase nevertheless.
