10:53 PM | New Zealand’s Southern Alps have lost a third of their ice
This article by Jim Salinger, University of Auckland; Blair Fitzharris, University of Otago, and Trevor Chinn, National Institute of Water and Atmospheric Research, was first published at The Conversation. The photo at left shows the calving face of the Tasman Glacier in Dec 2013. A third of the permanent snow and ice of New Zealand’s […]

1:37 PM | Roger Pielke Jr. on FiveThirtyEight and his Climate Critics
Earlier in the year, Roger Pielke Jr. was named as a contributing writer for Nate Silver’s newly re-launched FiveThirtyEight site. Shortly after that, Pielke, a climate policy scholar and political scientist at the University of Colorado, in Boulder, published an article at FiveThirtyEight headlined, “Disasters Cost More Than Ever–But Not Because of Climate Change.” Critics pounced immediately in […]The post Roger Pielke Jr. on FiveThirtyEight and […]

7:42 AM | Adventures in the Anthropocene
Science journalist Gaia Vince left her desk at Nature and spent two years visiting places around the world, some of them very isolated, where people were grappling with the conditions of what is sometimes described as a new epoch, the Anthropocene. It dates from the industrial revolution and represents a different world from the relatively […]

9:59 AM | Temperatures make our global warming opinions change like the weather
Our experience of current warmth can override our scientific knowledge in driving beliefs about climate change, which is part of the reason we struggle to take the resulting risks seriously, underlines Columbia University’s Elke Weber.

11:31 PM | Always ready to fight the last war
No happy ending for us tonight alas. We had a good start, and not one but two whistles on Tabs into Grassy, and all of that was the plan, but we lacked the oomph to close down the last half length plus the overlap. Which was the bit that wasn’t under our control. We also…

I should write up day 2 before day 3, else I’ll be coloured. There’s a riggercam video, again, but it will look pretty similar to yesterday unless you care, so instead here’s some footage from Grassy. This has the benefit of showing the handbrake – I’ll come to that. So, we’re now at 8, which…

8:45 PM | At last, Champs One
More nonscience, I’m afraid. When we left off the never-ending story last year we’d just bumped Press, and were rather regretting not getting a shot at Champs. Roll forwards a year, and its Tuesday again. We have six of our old crew back, losing Mr W and Dr H, and replacing them with old-hand-turned-fit Paul…

11:10 AM | CO2 emissions drive heatwaves on despite warming ‘hiatus’
Direct effects from greenhouse gases are playing a significant role in making hot Northern Hemisphere summers more common even as average temperature increases slow down, find Youichi Kamae from the National Institute for Environmental Studies in Japan and his colleagues.

The implications are clear enough: damage […]

7:00 PM | What Geology Has to Say About Global Warming
The most important lessons drawn from geology are that the earth’s climate can change radically and that the pace of change can be rapid. The precision of measurement is currently too poor to give an exact answer to a critical question, At what carbon dioxide level are we in danger of melting Antarctica? However, while crude, these estimates suggest that this threshold will be reached in 150-300 years, if carbon dioxide levels continue to rise at the current rate.
