Climate Change
gregladen | January 7, 2014Everyone laughed ... earlier today ... when Rush Limbaugh claimed that the Polar Vortex, the ginormous weather phenomenon that brought so much cold to Canada and the United States over the last few days, was created by Liberals.
If Liberals can indeed create a planetary-level weather phenomenon like the Polar Vortex, then Liberals are very powerful indeed and should not be messed with. Just sayin'
Anyway, people made fun of Rush Limbaugh for saying this. Peter Gleick, who blogs here, went so far as to tweet a Google ngram he did showing that the peak of use of the term "Polar Vortex"…
gregladen | January 7, 2014Extreme weather events of all kinds seem to be more common now than they were then. By now I mean the last five to ten years, approximately, and by then I mean ... well, before that. This is because of global warming.
The current Colding caused by a wandering Polar Vortex (which I've heard Rush Limbaugh has declared to be a liberal plot ... thanks Obama!) is probably a result of changes in the nature and configuration of the jet streams and related air masses, as discussed here. Warming caused by the release of fossil carbon, mainly as Carbon Dioxide, has affected the Arctic more than most…
gregladen | January 5, 2014If global warming is real, then why is it so cold?
We are hearing this question quite often today and it will be asked many times by many people over the next few days as record low temperatures are set in many parts of the United States. Here in Minnesota, for example, we have a good chance of setting a record low daily high beating the previous record of 14 degrees below zero F. We may or may not beat the record daily low but we are going to get close. (Donald trump is probably the most famous person to have gotten this wrong over the last few days.)
Global warming is real. The apparent…
gregladen | December 14, 2013In an ongoing effort to discredit mainstream climate science, climate contrarians have incorrectly asserted that there is a “pause” in the rate of global warming. This was never true, but now, it is even less true.
(Originally Published Here)
To any objective observer, the Earth is now a world warmed. The decade 2001–2010 was the hottest decade on record, and every single month since March 1985 has been warmer than the 20th century average. The present year promises to be the sixth warmest year on record. Already this year, our fellow Americans out West have been confronted by record…
gregladen | December 14, 2013The best way to not look like an idiot is to shut up. Works every time. Why just a few minutes ago I said something really stupid because I confused UPS and USPS. Should have just kept my mouth shut, but I didn't.
This time of year a lot of people start sounding like idiots, quite possibly because they are idiots (but see below for alternative explanations), when it comes to global warming. For example, someone who may or may not be a "global warming denier" (i.e. a person who does not believe in physics) sent me, out of the blue, this string of tweets:
First he tells me that the ice…
gregladen | December 14, 2013Surface temperatures are only one way to measure global warming, but it is a sort of standard and it is meaningful because surface temperatures have a lot to so with weather and such. Data for NASA's GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius using a base period of 1951-1980 can be found HERE. Climate Communicator ThingsBreak put a graph on the internet based on those data for November. Here's a copy of it:
Earth’s surface temperature in °C for each November since 1880 (compared to base period, 1951-1980). Stefan Rahmstorf, creator of the graphic, used the SSAtrend…
gregladen | December 7, 2013Please join us. It will be at the West Metro Critical Thinking Club on Saturday, December 28, 2013, at 10:00 AM at the RidgePointe Senior Apartments on 12600 Marion Ln. W, Minnetonka, MN.
I know these people. This will be a tough audience. This is a well educated and thoughtful group. Also, there are many climate skeptics in the group, and a talk given last September that questioned the strength of the evidence for Global Warming was well received. So, this is going to be interesting and fun!
Here's the writeup for the talk, and more info can be found HERE:
The Global and Local…
gregladen | December 5, 2013I've noted this before. Here is Peter Sinclair's video on the topic:
The most sobering evidence of the planet's response to greenhouse gases comes from the fossil record. New evidence scientists are collecting suggests that ice sheets may be more vulnerable than previously believed, which has huge implications for sea level rise.
gregladen | December 5, 2013Are there more tornadoes because of global warming? Are they stronger? Do they occur more frequently outside of the usual tornado season, or are they more common in areas that formerly had few tornadoes?
There are problems with all of these questions, and the main problem is the fact that the tornado data isn't very informative.
Here's the raw data from the NOAA tornado database, showing the number of tornadoes per year of all intensities greater than one mile long on the ground:
(Click on the graph to see the whole thing in case it isn't showing for you.)
This looks like more tornadoes…
gregladen | November 27, 2013An Update on #ClimateThanks.
Heather Libby has a nice piece on Climate Thanks here. The Denialists have started to spam the hashtag with their insipid, unoriginal drek. Tallbloke, whom I do indeed consider to be a criminal (as are the rest of them) carrying out crimes against humanity (he sued me once for saying that, which was totally lame) has even joined in, as have some members of the SlymePit adding that special MRA-Science Denailist crossover stink to the mix. But for the most part it is just good people thanking other good people for doing good stuff having to do with climate…

The IPCC has produced a video on its Fifth Assessment Report (AR5). The first part on the Working Group I contribution to AR5 is now available. The other parts will be released with the successive approvals of the other two Working Group contributions and the Synthesis Report in the course of 2014.

New Oil Change International interactive graphic shows growing fossil fuel reserves in contrast to shrinking global carbon budget
WASHINGTON, DC – New analysis by Oil Change International shows that global fossil fuel reserves continue to expand while the Intergovernmental Panel on Climate Change and other scientific and industry analysts repeatedly show that our remaining budget for burning fossil fuels has shrunk to less than one third of existing reserves.
The Oil Change analysis shows that fossil fuel companies gained access to more than twice as much in fossil fuels as they…
gregladen | November 26, 2013Here is a letter from the Yale Project on Climate Change Communication:
Dear Friends,
The Yale Project on Climate Change Communication has much to be thankful for, including wonderful support from our friends and colleagues. That is why this Thanksgiving, we’re giving #ClimateThanks. Together with the climate community, we are taking a moment to tweet or post who or what we are thankful for in the fight for a safe climate. Please tweet #ClimateThanks and help us raise awareness about the amazing things people here in the US and around the world are doing.
Starting on Monday, November 25th, as…
gregladen | November 25, 2013One Hiroshima, Two Hiroshimas, Three Hirosimas, Four
On August 6th, 1945, the United States military detonated what was to date the largest and most terrible bomb ever created by humanity in the city of Hiroshima Japan. Since that time, the word "Hiroshima" has come to mean awesome power. In fact, the energy released by this bomb is beyond comprehension by the average person. Aside from the unbelievable power associated with that one human made machine, we also think, when we think of the bomb dropped on Hiroshima, of horrible consequences arising from human activity. It does not matter what…
gregladen | November 23, 2013“Simply assuming that this is an interesting controversy that we should check in on occasionally is not correct. The survival of human civilization is at risk. The news media should be making this existential crisis the No. 1 topic they cover.”
That was Vice President Al Gore being quoted in a New York Times piece by the newspaper's public editor, Margaret Sullivan. Sullivan's article, "After Changes, How Green Is The Times?" examines environmental reporting since the Times dismantled its environmental reporting facility last January. Sullivan's analysis, which seems fair, actually shows…
gregladen | November 19, 2013Update on Haiyan/Yolanda Death Toll
The final figures are not likely in but the numbers have stabilized and we can now probably put a number to the human toll of this storm that will not change dramatically in the future, at least in terms of orders of magnitude. The current “official” death toll in the Philippines from Typhoon Yolanda/Haiyan is 6,009 with 1,779 missing and 27,022 injured, with the largest concentration of casualties in Eastern Visayas. This comes from a December 13th report of the National Disaster Risk Reduction and Management Council, which you can (probably) download here…
gregladen | November 13, 2013If I want to measure how much business a shopping mall gets, I can stand by an entrance way and count the number of people who go into the mall. If I stop every tenth person on the way out and frisk them for their receipts, I can estimate the per-person amount of money spent, and multiply that by ten to get an idea of how much business is represented by the particular entrance way I am sampling. This would work. I wouldn't know how much money was spent in the mall because I have no information about other entrance ways, but I could track changes over time in business, and I'd probably be…

Philippines delegate Naderev (Yeb) Saño, announces his decision to go on hunger strike on the first day of the COP19 Climate Change Summit in Poland, 11 November 2013.
Making an impassioned plea for action by the conference, he said that he would be fasting in solidarity with his country-folk until action to prevent climate change is forthcoming.
Saño received a standing ovation after describing the hardship suffered by Filipino's, including members of his own family, due to the "colossal" typhoon Haiyan which recently hit his…
gregladen | November 9, 2013At this moment, there is a guest post over at WUWT blog downplaying the size, strength, wind speeds, overall effects, and even the death toll of Super Typhoon Haiyan. Even as the monster storm steams across the sea to it's next landfall (probably as a huge wet tropical storm, in northern Vietnam and southern China), Anthony Watts and his crew are trying to pretend this monster storm didn't happen, and instead, that it was a run of the mill typhoon.
At the moment, nobody is really saying that Haiyan's strength, size, power, or even existence is specifically the direct result of global warming…
gregladen | November 6, 2013You probably already know about Michael Mann's book, "The Hockey Stick and the Climate Wars: Dispatches from the Front Lines."
The ongoing assault on climate science in the United States has never been more aggressive, more blatant, or more widely publicized than in the case of the Hockey Stick graph -- a clear and compelling visual presentation of scientific data, put together by MichaelE. Mann and his colleagues, demonstrating that global temperatures have risen in conjunction with the increase in industrialization and the use of fossil fuels. Here was an easy-to-understand graph that, in…
