2016 was the hottest year on record for the troposphere

For the troposphere, 2016 was the hottest year on record!

The troposphere temperatures for December 2016 have been released. The lower troposphere is recorded in UAH v6 beta 5 and RSS TLT v3.3. This report also covers RSS TTT for the troposphere (without the "lower") and follows pretty much the same format as previous monthly updates.

For RSS TTT (troposphere), 2016 was the hottest year in the record. Last month was the second hottest December on record.

The lower troposphere (UAH beta v6.05) also showed 2016 as the hottest year in the record. However, December was only the sixth hottest December on record, with 2015 the hottest.

Dumb as: Anthony Watts complains Hausfather17 authors didn't use FUTURE data

Anthony Watts is complaining that scientists didn't use data that has yet to be published. What?

He did post an article about Hausfather17, which I've just written about.  Anthony's almost as nuts about this one as he was about the NOAA paper, Karl15. His headline was: Yet another study tries to erase “the pause” – but is missing a whole year of data.

The new paper uses latest available data

The new paper uses data to the end of the full year that's currently available - 2015. Since the paper would have been completed some months ago (it's just been published), not only would December 2016 data not have been available (it isn't yet), but the most recent months this year would not have been available to the authors, unless they had a Tardis.

The winner is NOAA - for global sea surface temperature

There's a new paper out that shows that, contrary to what you'll read on denier blogs, NOAA's latest version of global sea surface temperature is probably the best and most accurate around. It's the closest to observations, when you compare it to measurements from moored and floating buoys, Argo floats and radiometer-based satellite records of sea surface temperature.

Umpteen denier protests

Lamar Smith

You might remember how climate hoax conspiracy theorists, professional disinformers and other deniers protested loud and long when NOAA scientists published a paper about the revised NOAA temperature data. The US House Committee on Science, Space, and Technology, led by arch denier Lamar Smith, harassed NOAA endlessly with subpoena after subpoena. A lot of the changes to the NOAA temperature record were a result of a new version of the global sea surface temperature data set, known as Extended Reconstructed Sea Surface Temperature, or ERSST v4. The papers on that were published in February 2015 (see below). The protests only came, though, in June 2015 when there was a paper by Karl et al. That paper pushed denier buttons because it challenged the so-called "hiatus". You can read about Karl15 here, and the paper itself is here.

Insignificant record warming and other climate remarkables from deniersville

Despite climate science deniers thinking global warming will stop on 20 January, there is little changed in climate conspiracy land. It's just more of the same old denier memes that have been circulating for years. At WUWT they've had John Christy going on about CO2 being plant food, and some very detailed work to try to prove something or the other about the medieval climate anomaly (see the interactive map and references here).

Deniers still enraptured with medieval warming

Regarding the latter, I'm not sure that deniers know that it was climate scientists who did the hard work to determine the extent and timing of warmer and cooler periods in recent history. (In climate terms, the Holocene is recent history.)  Many of them have some odd notion that climate scientists, who've been the ones finding out about the past, have also been trying to "cover up" what they've found.

Deniers are a odd bunch.

Luddite Eric Worrall huffs and puffs and wants to bring back smog @wattsupwiththat

This is interesting. Probably without knowing it, Eric Worrall at WUWT is arguing for a national strategy for the shift to renewable energy. He was writing about an anti-renewables article in The Australian. In part, the article was about how, in the absence of a national electricity strategy, more people will leave the grid. However, the article was clearly propaganda against the shift to renewables, as is the norm for The Australian and it's war against humanity.

That article in The Australian was a Murdoch slant on the preliminary report released last month by the Energy Expert Panel, chaired by the Chief Scientist, Dr. Alan Finkel: Independent Review into the Future Security of the National Electricity Market (saved here).

Wishing you all Happy New Year

It's New Year's Eve where I live, so let me wish everyone a very happy, healthy and safe 2017.

This coming year is high risk from many perspectives. Climate change is an ongoing threat and will undoubtedly cause problems in many locations. It will contribute to civil unrest, food shortages, and more extreme weather events. The rise of corporations running governments is a threat to people everywhere, including those places where it's not happening to the same extent because of the on-flow impact on world trade. There is a heightened threat to world-wide security with the election of the unstable, reckless Donald Trump to the highest position in the USA. There is a threat to science and a devaluation of knowledge, which are being disregarded in many countries particularly in the USA, Australia, the UK. Many people in power are actively pursuing plans and policies to spread falsehoods on a scale that is unimaginable to some. The tactics being used are very familiar to those of us who've been watching them applied to climate information: smear the experts, create fake experts, make up false "facts", appeal to greed and fear and bigotry.

We cannot afford to just sit back and wait to see what happens. This is a time to take action in whatever way we can.

While some people are worse off and for some their circumstances have changed little, most people in the world have never been better off materially or health-wise than they are today, yet they have elected corrupt leaders or had them foisted on them, in part because their expectations exceeded the reality. We have allowed the wrong people to run (ruin) the world, people who are motivated not by any intent to make the world a better place, but by greed and a lust for personal power at the expense of the world as a whole.

Don't let them get away with it.

I'm sorry to write such a downer article while wishing you all a Happy New Year. We are on the edge of a dangerous precipice. Let's not fall into it.

Deniers hang their hopes on wrong information from a government website in Wisconsin

It's not clear that the partial scrubbing of climate change from the website of the Department of Natural Resources in Wisconsin was at the directive of the Governor Scott Walker, or if there happens to be a stray science denier who got lodged in the Department itself. What is clear is that it's got climate conspiracy theorists at WUWT enthused and hopeful. They seem to think that if the words "climate" and "change" are scrubbed from government websites, then global warming will stop. It won't.

(Scott Walker was a presidential hopeful at one stage, and reportedly dodged questions on climate change.)

Anthony Watts is so excited about this latest bit of climate censorship that he's posted two articles about it. One was written by Bob Tisdale (archived here) and the other by Kip Hansen (archived here).

Denier weirdness in Las Vegas, and WUWT wages war on clean energy in California

This comment can be seen at WUWT today, under another article by Eric Worrall (archived here). (Eric was protesting California's intent to modernise the energy sector. He prefers smog and dangerous climate change.)

Before I post the comment, you may have read how Las Vegas has joined other cities in the USA and shifted to 100% renewables, which is is expected to save the city an annual $5 million in operating costs. It's the city that's shifted, not all of the strip. On the official Las Vegas blog, it was announced that:

This morning, Mayor Carolyn G. Goodman and NV Energy Senior Vice President of Customer Operations Pat Egan announced that we are the first large city in the country and one of the first major customers in Nevada to be served exclusively with renewable energy. We are now one of the few cities of the world that can say all the power we use comes from a green source.  In partnership with NV Energy, every streetlight, city park, community center, fire station, service yard and public building owned by the city, totaling 140 facilities, will be 100 percent powered by renewable energy.

All the power used by the city itself now comes exclusively from renewable energy. While that doesn't mean that all the power used on the strip or in households come from renewable energy, it's a big step forward. On Snopes, it was pointed out that some businesses on the strip are following suit because it makes good business sense.

A climate science denier, John Barry, loses his #climate cool on Twitter

You'd think climate science deniers would be more laid back these days, basking in the election of an anti-science billionaire, Donald Trump. Instead, it seems to me they've just got more upset with climate science. Maybe they are figuring out that Trump won't stop climate change and can't change scientific knowledge.

This little exchange is quite typical of anti-science deniers and climate conspiracy theorists. Deniers are such fake sceptics that they cannot bear to see tweets from a climate hawk on Twitter, as this episode with John Barry @CardsFanTX illustrates.

To explain - this just happened. Someone called John Barry @CardsFanTX tweeted me, before blocking me. He made an easily disproven statement (link):

Happy Holiday

Happy holiday one and all. It's Christmas at our place, and we'll be having a family get-together, on a warm 38 C (100 F) sunny day.

Whatever you're up to, be happy, stay safe, and enjoy the break if you're lucky enough to have one.

PS If you think I'm jumping the gun, it'll be Christmas Day in just half an hour here :)
