Which Satellite Data?

“among the satellite data sets, there’s one which shows far less warming: UAH TMT. [The deniers] make a habit of showing the one satellite data set which shows the least warming and correlates least with balloon data.”

Open Mind

There are five data sets of global average temperature in the troposphere (the part of the atmosphere where our weather occurs) based on satellite data, from the two main providers, RSS (Remote Sensing Systems) and UAH (University of Alabama at Huntsville). UAH provides two of them: TLT (temperature in the lower troposphere) and TMT (temperature in the mid-troposphere); while RSS provides three: TLT, TMT, and TTT (temperature in the total troposphere). They’re all different, and each has gone through a number of revisions since the satellites began collecting data in 1979.

WIldfires increasing and not in the climate models

More forest fires

A post from Neven’s Arctic Forum by contributor AbruptSLR says

The linked Scribbler article is entitled: ‘“Surreal” U.S. Wildfires Should Not be Burning in Mid-November’.

https://robertscribbler.com/2016/11/17/surreal-u-s-wildfires-should-not-be-burning-in-mid-november/

Extract: “In Dallas, on November 16, the thermometer hit 88 degrees Fahrenheit, breaking a 95 year old record. In Ada, Oklahoma the mercury struck 85 degrees F. Further north in high-elevation Denver, temperatures soared to 78 F — punching through a 75 year old record.

Meanwhile, strange, out-of-season wildfires continued to burn from the U.S. South to North Dakota and New England. In Atlanta, smoke streaming out of nearby wildfires blanketed the city. Red-eyed residents were increasingly forced to don protective masks beneath the choking late-fall pallor. In Chattanooga, over 200 residents were hospitalized from smoke inhalation and shortness of breath.

Wildfires are missing from the climate models

Just before they were abolished the UK Government’s Department of Energy and Climate Change said

the [climate] models  used vary in what they include, and some feedbacks are absent as the understanding and modelling of these is not yet advanced enough to include. From those you raise, this applies to melting permafrost emissions, forest fires and wetlands decomposition.

Thawing permafrost isn’t in the models either

Scientific American warns about thawing permafrost

Sea Ice Update

More statistics that only fools would deny.

Open Mind

This year witnessed a September minimum of Arctic sea ice which was only the 2nd-lowest on record. But the year’s minimum isn’t the surprising thing about this year’s sea ice. That would be the surprising lows observed during May and part of June, and now, it seems, during the most recent few days of October. Here’s the data, with 2016 in red:

It’s the Ice, Stupid

Open Mind

Earlier this month the WUWT blog treated us to a bizarre post about how this year didn’t set a new record for lowest Arctic sea ice extent (it only came in 2nd-lowest), in spite of “two very strong storms.” Doubling down, they offer another post trumpeting “record Arctic sea ice growth in September.” Which makes me wonder: are those guys trying to make themselves look like idiots?

1.5 Degrees: Meeting the challenges of the Paris Agreement

This is my comment on an article by Carbon Brief
Highlights: Day one at the 1.5C conference on climate change in Oxford

The website related to the conference can be found at “1.5 degrees

My comment on Carbon Brief:

Thanks to Carbon Brief and Rosamund Pearce for an excellent report.

There are a few points I will make.

[1] In the embedded  video, Professor Corrinne Le Quere says

“[to keep within 1.5°C] it is necessary to be “completely de-carbonising the economy in just a few decades.”

Earlier this year Carbon Brief said

Analysis: Only five years left before 1.5C carbon budget is blown”.

There is a big difference between “a few decades” and five years.

[2] Corrine also says “Global emissions have stalled in the past few years”. Apart from the fact that “stalled” is nowhere good enough to keep within 1.5°C , this reduction is not yet seen in the increasing concentrations of CO2 in the atmosphere.

Brian Cox’s Denier Takedown: a High Point for Climate Journalism

The BBC should let Brian Cox give the same treatment to Lord Nigel Lawson and the sceptics of the Global Warming Policy Foundation. The BBC have been reprimanded for giving Lawson too much credence in the past.

Open Mind

Many have enjoyed the smackdown which Brian Cox delivered to Malcom Rogers on Australian TV’s program “Q&A”. Myself included. Cox is a scientist, and one of the most popular science communicators in Britain (perhaps England’s answer to Neil deGrasse Tyson?). Roberts is a politician, a senator no less, in Australia. He’s also a climate denier.
