9:25 PM | Protect the Earth, Dignify Humanity. The Moral Dimensions of Climate Change and Sustainable Humanity?
It am de Pope, he be at it agen. Dere be no stopping dis righteous Pontifex. Just for the moment, he’s saying things that I broadly agree with, but that doesn’t mean I’m going to start being happy with religious authority. There was a one-day “seminar” or “workshop” or “event”, Protect the Earth, Dignify Humanity.…

8:48 PM | How long does it take Antarctica to notice the Northern Hemisphere is warming?
Eric Steig A series of large and abrupt climate changes occurred during the last ice age, most clearly expressed in ice cores from Greenland and other paleoclimate data rom the circum-North-Atlantic region. Since the discovery of these events, we’ve been trying to pin down the timing of abrupt climate changes elsewhere on the globe. Were […]

8:11 AM | Milk cow blues: dirty dairy costs NZ dear, but methane cuts might work
There’s good news and bad news for New Zealand’s dairy industry this week. On the one hand, research has found a number of compounds that can cut methane emissions from ruminants (cows and sheep) by up to 90% by reducing populations of the bacteria that produce the gas. On the other hand, research into the […]

8:00 PM | Two new reviews of the homogenization methods used to remove non-climatic changes
I’ve stolen VV’s title. Why not? He’s the man who knows. Moyhu also has something interesting to say. All I have to say is: WTF? In case you’ve missed it, there’s a real one, and then there’s the GWPF’s comedy one. You can read the GWPF’s stuff at tempdatareview.org, though why you’d bother I don’t…

9:31 PM | Now we know why UAH v6 is so late…
I said that AFAIK S+C’s code for UAH isn’t available but VV pointed me to Eli who pointed me to ncdc.noaa.gov/cdr/operationalcdrs.html which offered me RSS and UAH. UAH is the one we want to take the piss out of, so read it and weep, below. First, though, as far as I can tell it doesn’t…

2:02 AM | Climate battle at NBR: Rodney’s rubbish versus Wiggs wisdom
New Zealand’s leading business media outfit — the National Business Review — has long dallied with climate denial, providing a platform for former ACT party leader Rodney Hide (amongst others) to push climate tosh. Last week Rodney used his regular opinion column to attack the government’s emissions policies (behind paywall) — fair enough, given that […]

3:08 PM | Nenana Ice Classic 2015
Unsurprisingly to anyone looking at the exceptionally warm winter on the West Coast of North America, the Nenana Ice Classic had another near-record early breakup on Friday, netting some lucky winner(s) around $300,000 in prizes. As I’ve discussed previously (last year and an update), the Ice Classic is a lottery that has been run every […]

12:08 PM | The return of the iris effect?
Guest commentary from Andy Dessler (TAMU) When a new scientific hypothesis is published, two questions always occur to me: Did the authors convincingly show the hypothesis was correct? If not, is the hypothesis actually correct? The answers to these two questions may not be the same. A good example is Wegener’s theory of continental drift […]

1:33 PM | An Online University Course on the Science of Climate Science Denial
Guest post from John Cook, University of Queensland For many years, RealClimate has been educating the public about climate science. The value of climate scientists patiently explaining the science and rebutting misinformation directly with the public cannot be overestimated. When I began investigating this issue, my initial searches led me here, which was invaluable in […]

11:00 AM | A Climate Battle Cry for Earth Day
A group of 17 renowned scientists from around the world are appealing for dramatic action to forestall the worst effects of climate change, issuing an “Earth Statement” that calls for a world powered with zero carbon emissions by mid-century.

8:54 AM | Wikipedia: Grant Shapps
By popular request. And I’ve not seen anyone else wiki-literate discussing this, so I will. the Graun says Grant Shapps accused of editing Wikipedia pages of Tory rivals. Online encyclopedia administrators block user account believed to be run by Tory party co-chairman or ‘someone else … under his clear direction’. Wikipedia has blocked a user…

8:51 PM | I lose. Or win. It depends. 3:55:53, anyway.
Another in my marathon posts, but! To a new city, Rotterdam. Which is indeed a fairly new city, having been bombed to buggery (by us, mostly, I presume) during WW II. Anyway, TL:DR: 3:55:53. Which is one second slower than Amsterdam 2012. Here’s my list, in order: * Brighton 2011: 4:20:32. * Amsterdam 2014: 3:58.02.…

1:40 PM | A Scientific Debate
Guest posting from Bill Ruddiman, University of Virginia Recently I’ve read claims that some scientists are opposed to AGW but won’t speak out because they fear censure from a nearly monolithic community intent on imposing a mainstream view. Yet my last 10 years of personal experience refute this claim. This story began late in 2003 […]

11:27 PM | The encroaching sea: new NZ sea level rise maps
This guest post is by Jonathan Musther, who has just published an amazing series of highly detailed maps projecting future sea level rise scenarios onto the New Zealand coastline. If you live within cooee of the sea, you need to explore his maps. Below he explains why he embarked on the project. The effect of […]

6:11 PM | We win!
Good race, too, at least for the first half. Oxford up a few seats off an untidy Cambridge start, then they pull back, and I thought we’d lose it round the bend but no. Got very tense, boats close together. And then suddenly just after Hammersmith: whoompf and they’re through, and Cambridge can eat our…

9:10 PM | All of this will soon be moot, anyway
No, don’t worry, I’m not giving up. Its is a quote, provided somewhat tactlessly by the normally urbane Crandles: All of this will soon be moot, anyway. Since last year we have been working on v6.0 of the UAH datasets which should be ready with the tropospheric temperature datasets before summer is out. Who said…

9:46 PM | She don’t make me nervous, she don’t talk too much
Obscure, perhaps, but I claim it was by request. My sermon is taken from Removing Diurnal Cycle Contamination in Satellite-Derived Tropospheric Temperatures: Understanding Tropical Tropospheric Trend Discrepancies by S Po-Chedley, T Thorsen and Q Fu, but before I get onto that I need to snark a bit; where would the world be without such?
