The Climate Show #8: Kevin Trenberth and our shaky future

By Gareth Renowden 03/03/2011


The Climate Show returns with a packed show, featuring one of the world’s best known climate scientists, NZ-born, Colorado-based Dr Kevin Trenberth — star of the Climategate “where’s the missing heat” emails. He’s been in New Zealand to visit family (experiencing the Christchurch quake in the process) and to attend a conference, and his comments on the state of our understanding of climate change should not be missed. John Cook of Skeptical Science returns with his new short urls and an explanation of why declines have never been hidden, and Gareth and Glenn muse on Arnie “Governator” Schwarzenegger riding to the rescue of climate science, cryospheric forcing and carbon cycle feedbacks from melting permafrost, and a new paper that suggests that current policies are pointing us towards extremely dangerous climate change. All that and hyperbranched aminosilica too…

News & commentary:

Christchurch earthquake, Feb 22 2011. At the time of writing the death toll was expected to rise to over 240. At least 100 of those who died were tourists or foreign students. If you would like to donate to support the recovery effort, please consider the Red Cross appeal.

Schwarzenegger: It’s Time to Terminate Skepticism on Climate Change

Good northern hemisphere cryosphere graphic from NASA, and bad news from the permafrost.

Models guiding climate policy are ‘dangerously optimistic’: Computer models predicting future climate change are underestimating emissions and overestimating technology, warns climate scientist Kevin Anderson. Guardian story here, and full paper [Anderson and Bows. Beyond ‘dangerous’ climate change: emission scenarios for a new world. Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences (2011) vol. 369 (1934) pp. 20-44 — PDF], and Bryan Walker’s discussion at Hot Topic.

Increased flood risk linked to global warming

Feature interview:: Kevin Trenberth, head of the Climate Analysis Section at the National Center for Atmospheric Research in Boulder Colorado. Born in NZ, worked at MetService, now based in Colorado, one of the highest profile climate scientists in the world, and a regular subject of attacks by denialists. The AMS paper referenced is available from KT’s web site linked above.

Clearing up misconceptions about ’Hide the Decline’

1. It’s not about ’global temperatures’ but a small number of high latitude tree rings:

2. ’Hide the decline’ has nothing to do with ’Mike’s trick’ which is the simple technique of plotting instrumental temperature and reconstructions on the same graph.

3. It’s not hidden at all but openly discussed in the peer-reviewed literature since 1995:
