9:49 PM | Four Revolutions in the Earth Sciences
James Lawrence Powell is a former geology professor, college president and museum director. He is currently the executive director of the US National Physical Science Consortium. He is also an excellent communicator of science for the general reader. I reviewed two of his climate change-related books back in 2011 here and here. His latest book, Four […]

9:55 PM | Naval gazing
I can thoroughly recommend the reviews. but this post, as I’m sure you’ve already guessed, is not about common problems with perforce but about ScienceBlogs. Or National Geographic blogs, I’m never quite sure what “we” are nowadays. But nonetheless I was surprised by Sb Has 19 Active Blogs (of which I’m one, of course, though…

6:39 PM | “the Monckton et. al paper is complete trash”
Or so says Gavin in How Climate Change Denial Still Gets Published in Peer-Reviewed Journals via Retraction Watch. Dountless Monkers will welcome yet another chance to bluster and threaten to sue1. The paper has been “harshly criticized by physicists” (who knew ATTP was plural, eh?) and “climate scientists” though to be fair ATTP only really…

4:06 PM | Thoughts on 2014 and ongoing temperature trends
Last Friday, NASA GISS and NOAA NCDC had a press conference and jointly announced the end-of-year analysis for the 2014 global surface temperature anomaly which, in both analyses, came out top. As you may have noticed, this got much more press attention than their joint announcement in 2013 (which wasn’t a record year). In press […]

10:00 AM | The wrinkled retainer returns with a Peer-reviewed Peer
There is much ado at Tannochbrae Manor, because the Laird has once again disproved global warming. One equation is all it takes! And an article in a new Chinese science journal with some friends, and lo! Take away that inappropriate and misapplied equation, remove the unjustifiable tripling and the climate “crisis” vanishes. You couldn’t make […]

8:44 PM | These go up to 11
Shamelessly stolen from ATTP’s “More than half” is the same as “> 50%”!, but I think this captures brilliantly a typical argument with the “skeptics”: TPP has a link to the interesting story of Alfred Russel Wallace‘s bet with the flat-earthers that the Earth was, in fact, not flat. Somehow, that seems relevant. While I’m…

7:30 PM | Humanity Is In The Existential Danger Zone, Study Confirms
The Earth's climate has always changed. All species eventually become extinct. But a new study has brought into sharp relief the fact that humans have, in the context of geological timescales, produced near instantaneous planetary-scale disruption. We are sowing the seeds of havoc on the Earth, it suggests, and the time is fast approaching when we will reap this harvest.Read more...

12:09 AM | Heat: 2014 breaks global temperature records, 2015 could be hotter
Last year was the warmest year on record for the planet, analyses by NASA and NOAA show, and it’s possible that 2015 could be warmer still. 2014 was warmer than previous record holders 2005 and 2010, and comfortably ahead of 1998. 13 of the hottest 15 years on record have all occurred since 2000. Remarkably, […]

8:45 PM | How much is climate change going to cost us?
Its been a bit quiet around here. Don’t fear: a whole variety of things have wound me up recently, not least my colleagues inability to use perforce competently1. But none of them quite rose to the level of bothering to post. I was going to write something gratuitously offensive about the Charlie Hebdo stuff, but…

11:40 PM | Yep, 2014 Was The Hottest Year In Recorded History
Two independent analyses by NASA and NOAA have both concluded 2014 was the warmest year ever recorded on Earth – hotter, even, than 2010, the previous record-holder in a field of contenders stretching all the way back to 1880.Read more...

NASA, NOAA, and JMA numbers concur.

7:01 PM | Empty seas? Scientists warn of an industrialized ocean
This is obvious, but still important: humans are not a marine species. Even as we have colonized most of our planet's terrestrial landscapes, we have not yet colonized the oceans. And for most of our history, we have impacted them only on the periphery. A new review in Science finds that this has saved marine species and ecosystems from large-scale damage—that is, until the last couple centuries.

7:43 PM | A new sea level curve
The “zoo” of global sea level curves calculated from tide gauge data has grown – tomorrow a new reconstruction of our US colleagues around Carling Hay from Harvard University will appear in Nature. That is a good opportunity for an overview over the available data curves. The differences are really in the details, the “big […]

11:41 AM | Diagnosing Causes of Sea Level Rise
Guest post by Sarah G. Purkey and Gregory C. Johnson University of Washington / NOAA I solicited this post from colleagues at the University of Washington. I found their paper particularly interesting because it gets at the question of sea level rise from a combination of ocean altimetry and density (temperature + salinity) data. This […]

9:45 PM | Getting rid of old stuff
None of the following are warranted in any way. I’m just clearing out some old emails and didn’t want to completely throw them away. This may be only of interest to me, and possibly not even me. * Spock warns of coming ice age * Slowing down as an early warning signal for abrupt climate…

9:15 PM | Your Life as Planet Earth
“We can’t make sense of our future until we make sense of our past”, writes Howard Lee in his recent book Your Life as Planet Earth: A new way to understand the story of the Earth, its climate and our origins. The book demonstrates the very considerable sense that science has been able to make […]

7:11 PM | WATN: Force X from outer space
In my Where are they now? review of 2014, I unforgiveably forgot the sensation of the year, Force X from outer space. Its worth reviewing, because (a) its not quite dead yet (or perhaps more accurately its proprietors haven’t yet given up hope of revivifying it) and (b) the original played out for so long…

9:44 PM | Greg Craven’s viral climate ‘decision grid’ video
This got mentioned in early 2014 at Planet3.0. To be fair to mt, he wasn’t really pushing the video itself, just using it to illustrate his point (which I think is uncertainty-is-not-your-friend; I agree with that), though he did call it “excellent”. But since, as I said in the comments there I don’t think its…

9:31 PM | Anthropogenic influence on recent circulation-driven Antarctic sea ice changes
Oh good grief I hear you cry, not more science. Yes. Sorry. And its even about sea ice, but the Antarctic kind. This is in the trail of Holland and Kwok and so on. Observations reveal an increase of Antarctic sea ice over the past three decades, yet global climate models tend to simulate a…

8:47 PM | No growth stimulation of tropical trees by 150 years of CO2 fertilization but water-use efficiency increased
As an experiment, I thought I’d try posting some science instead of nonsense or mountains. From Nurture (Peter van der Sleen et al., Nature Geoscience 8, 24–28 (2015) doi:10.1038/ngeo2313): The biomass of undisturbed tropical forests has likely increased in the past few decades1, 2, probably as a result of accelerated tree growth. Higher CO2 levels…

I wander thro’ each charter’d street, Near where the charter’d Thames does flow. And mark in every face I meet Marks of weakness, marks of woe. In every cry of every Man, In every Infants cry of fear, In every voice: in every ban, The mind-forg’d manacles I hear Over the year a number of…
