Link between tornadoes and climate change

Recent bad weather in the US, for example the tornado which mashed Joplin, Missouri, has led to many many stories speculating about the link between the intense tornado season and climate change. Joe Romm at Climate Progress takes a measured view:

1. When discussing extreme weather and climate, tornadoes should not be conflated with the other extreme weather events for which the connection is considerably more straightforward and better documented, including deluges, droughts, and heat waves.

2. Just because the tornado-warming link is more tenuous doesn’t mean that the subject of global warming should be avoided entirely when talking about tornadoes.

Joe Romm’s substantive post Tornadoes, extreme weather, and climate change is well worth a read and has lots of comments and links about extreme weather in general as well as tornadoes. Continue reading Climate clippings 28 →

Gillard’s speech goes global

On 16 March 20011 Julia Gillard gave a speech to the Don Dunstan Foundation.

Climate Progress picked it up, quoted a long slab and highlighted these bits with approbation and the wish that Barack Obama would do as well:

Australians of the future will look back on [opposition leader Tony] Abbott’s campaign with pity and shame. The pity and shame posterity reserves for leaders who miss the wave of history and misjudge the big calls.…

We will cut carbon pollution. We will not leave our nation stranded by history. We will not live at the expense of future generations. We will get this call right and get this job done: For our nation. For our people. For our future.

It’s a mighty fine speech, but why did I have to find out about it from the other side of the world? Continue reading Climate clippings 22 →

Garnaut Update Paper 5: The science of climate change

Garnaut’s series of update papers has now reached Update Paper 5: The science of climate change. This is worth a longer look, but suffice it to say here that the sense of urgency has grown considerably.

  • Observable trends seem to be running ahead of predictions.
  • The 2C limit looks high and may in fact represent the boundary between dangerous climate change and extremely dangerous climate change.
  • 450 ppm looks high, but we are going to shoot through it.
  • Garnaut has picked up on the “emissions budget” approach I have been banging on about. On present trends we (the world) will use up our remaining budget of allowable emissions in a couple of decades.
