Climate change justice is contentious

As this round of the IPCC unfolds, developing countries are scurrying to relieve themselves of any major responsibility for historic emissions and, consequently, aggressive mitigation policies.

For example, China has requested inserting language that formally recognizes the percentage of emissions for which developed countries are responsible -- 95 percent from the pre-industrial era until 1950, and 77 percent from 1950 to the start of the millennium.

More current science paints an even grimmer picture

Already, there are serious reservations about the final IPCC summary for policymakers, which was released today.

The BBC leads the charge, noting that the economic models used to recommend mitigation policies aim to hold the atmospheric carbon dioxide concentration at 550 parts per million (ppm). However, more recent scientific evidence suggests, and I agree, that our policies need to keep concentrations much closer to 450 ppm.

Bad news from down south

Scientific and observational data from Antarctica are driving home the message that we have entered a period of consequences.

Most recently, scientists have discovered ice streams hiding bigger reservoirs of water in West Antarctica. The evidence has "major implications for glacial melt rates and associated sea-level rises" and the rate of warming.

And their PM is still in denial

Australian Prime Minister John Howard is in a sticky, yet dry, situation.

Even though a drought has caused Australia's agricultural production to fall 25 percent in the last year, Howard may have to ban irrigation so that urban centers can have drinking water.

The targeted river basin, the Murray-Darling, is known as Australia's "food bowl" because it houses 72 percent of Australia's farm and pasture land. If insufficient rain continues through the next few weeks, this year's harvest will be devastated and cities will need to implement water usage restrictions.

Prime Minister Howard doesn't accept the connection to global warming, but scientists and farmers disagree, saying "this drought has the fingerprints of climate change all over it." In climate models, Australia is predicted to be one of the first areas seriously impacted.
