The value of very long instrumental data series

Climate Etc.

by Alan Longhurst

Because the climate change science community habitually concentrates attention on surface data from a very short recent period – nominally a little more than 100 years – it would be very interesting to know how the pattern habitually derived from these data compares with longer data archives that have been processed independently by the observing nations.

The Divergence between Surface and Lower Troposphere Global Temperature Datasets and its Implications

Watts Up With That?

Guest Post by Bob Tisdale

I include a graph in my monthly global surface temperature and lower troposphere temperature anomaly updates that compares the average of the global surface land+ocean temperature anomaly products (from GISS, NCEI and UKMO) to the average of the global lower troposphere temperature anomaly products (from RSS and UAH).  (See Figure 9 from the most recent August update for an example.) Because all of the suppliers use difference base years for their anomalies, I’ve recalculated the anomalies for all using the WMO-preferred reference period of 1981-2010.


Figure 1

My Figure 1 is similar to Figure 9 from those updates, but in it, I’ve also shown the linear trends for the global surface and lower troposphere temperature anomaly products.  The linear trend, the warming rate, presented by the average surface-based products is noticeably higher than the average lower troposphere products.   This, of course, according to Dr. Gavin…

Federal Court Delivers Stunning Blow to Mass. AG and #ExxonKnew Campaign

Watts Up With That?

By Katie Brown. (h/t to Matt Dempsey)

In yet another stunning blow to the #ExxonKnew campaign, a federal judge today issued a discovery order against Massachusetts Attorney General Maura Healey to determine whether “bias or prejudgment” influenced her decision to initiate a “bad faith” investigation into ExxonMobil, just days after she appeared before news cameras with New York Attorney General Eric Schneiderman, Al Gore and other Democratic state attorneys general in New York.

As the Washington Post reported this afternoon, this “new discovery order could open the door for an intrusive examination of Maura Healey ’s internal phone records, other communications and depositions,” shedding light on the extent to which Healey, Schneiderman and others have conspired with outside activists, plaintiff attorneys and partisan political interests to carry out their failed #ExxonKnew campaign.

We know from FOIA’d emails that the AGs in Schneiderman’s climate coalition tried to hide behind a Common Interest…

Study: Extraterrestrial impact preceded ancient global warming event

The truth is in there.

Watts Up With That?


Troy, N.Y. — A comet strike may have triggered the Paleocene-Eocene Thermal Maximum (PETM), a rapid warming of the Earth caused by an accumulation of atmospheric carbon dioxide 56 million years ago, which offers analogs to global warming today. Sorting through samples of sediment from the time period, researchers at Rensselaer Polytechnic Institute discovered evidence of the strike in the form of microtektites – tiny dark glassy spheres typically formed by extraterrestrial impacts. The research will be published tomorrow in the journal Science.

“This tells us that there was an extraterrestrial impact at the time this sediment was deposited – a space rock hit the planet,” said Morgan Schaller, an assistant professor of earth and environmental sciences at Rensselaer, and corresponding author of the…

President Obama’s Parting Gift – the Green Pork Plan

Watts Up With That?


Guest essay by Eric Worrall

The Washington Examiner claims President Obama is on the verge of stitching up a deal to pass a massive raft of green pork tax credits in the final weeks of his Presidency, after the November Presidential election.

Obama readies clean energy ‘end-game’

The White House is devising an “end-game” strategy to pass a suite of clean energy tax subsidies that were swept to the wayside in last December’s omnibus spending bill deal, said a top White House official.

The tax credits were not attached to last year’s spending bill, although the measure did include a landmark deal extending wind and solar subsidies for five years with an incremental phase out. The orphaned clean energy subsidies that were left out of the deal are for things like hydrogen fuel cells, renewable fuel infrastructure, geothermal and other alternative energy resources.

Attempts to include the extensions in…

U.S. sees lower energy costs while Australia and Europe’s renewable energy mania creates energy price spikes and supply disruptions

Watts Up With That?

Guest essay by Larry Hamlin

The Energy Information Administration released electricity price data on October 6 for the first 6 months of 2016 showing lower residential prices compared with the same period in 2015 largely driven by lower cost natural gas availability.


Also on October 6 Australian Prime Minister Malcolm Turnbull slammed renewable energy obsession for causing South Australia’s energy price spikes and state wide blackout.

Turnbull told the countries energy ministers that excessive reliance on wind turbines are wrecking Australia’s power grid stability which is undermining the country’s energy security. (

Household electricity prices in Australia have risen 40 percent between 2007 and 2012 with Australian states pushing heavily subsidized wind energy reliance having rates nearly double those of other states.

In addition to the recent wind energy caused state wide blackout in South Australia electricity price spikes there have occurred pushing rates to 8 times higher…
