TDB Today: WACCy weather and a warm year

by Gareth January 29, 2014

A classic case of WACCy weather in the northern hemisphere, seen here in a map from the excellent Climate Reanalyzer site, prompts me to discuss the 2013 global temperature numbers, the El Niño-Southern Oscillation, and what sea ice loss is doing to northern hemisphere weather patterns in my post at The Daily Blog this week.

Moon-walking with due legal process to a very hot place – Neil Armstrong, coal mining & global warming

by Mr February August 30, 2012

On the same day as the death of Neil Armstrong, the first astronaut to step onto the Moon, became public, the NZ High Court moonwalked its way to an off-the-world moment. It decided that greenhouse gas emissions and global warming are off-limits in the planning for an open cast coal mine. That’s as just as […]

Uncertainty overdone

by Bryan Walker May 21, 2012

Earlier this month James Hansen wrote a trenchant op-ed in the New York Times.  He reiterated the warning that the exploitation of the Canadian tar sands will be game over for the climate, spelt out some of the long-term drought consequences for the US of continued warming and identified notable heat waves of the last […]

Hansen’s righteous cause

by Bryan Walker April 19, 2012

The latest communication from James Hansen to his email list this week was a sharp reminder that the New Zealand Government’s commitment to the pursuit of unexploited fossil fuels is part of widespread malpractice. The global stampede to find every possible fossil fuel is not being opposed by governments, no matter how dirty the fuels […]

The Hockey Stick and the Climate Wars

by Bryan Walker February 21, 2012

It was clearly never Michael Mann’s wish to be embroiled in the public controversy that has been manufactured by the denial industry around his and his co-authors’ work. He’s a scientist first and foremost, the nine-year-old who wanted to know what it meant to go faster than the speed of light, the high school student […]

The unfettered rage of dismal denial

by Bryan Walker February 10, 2012

I knew that climate scientists were on the receiving end of some nasty emails, but it was still a shock to read James Hansen’s recent communication, in the course of which he gives a sample of the emails that he’d had in just the one week. They’re a dismal example of the unfettered rage which […]

The NASA numbers are in, and 2011 was the ninth warmest year since 1880 — 0.51ºC above the 1951-80 global mean. Nine of the ten warmest years in the long term record have occurred in this century. According to the analysis released by James Hansen and his team at GISS, a combination of low solar […]

Hansen: extreme heat the new normal

by Bryan Walker January 11, 2012

James Hansen and two fellow-authors have circulated a new paper which they will be submitting for publication, Perceptions of Climate Change: The New Climate Dice. I’m not qualified to comment on its scientific detail beyond reporting it as relatively accessible to the lay person, but there were elements in the discussion with which it concluded […]
