Greenland Temperatures & The AMO

by P. Homewood, June 13, 2021 in NotaLotofPeopleKnowThat


It’s not new, but it’s worth going over it again.

We have seen how Greenland temperatures rose sharply in the 1920s, and remained at levels similar to the last decade until the 1960s, when they fell equally sharply. This change in climate is closely interlinked with the Atlantic Multidecadal Oscillation (AMO), which switches from cold to warm phase, and back again, roughly every 50 to 60 years:

US Government Tries To Erase Historical Forest Fire Data To Fabricate Another Fake Crisis

by P. Gosselin, June 8, 2021 in NoTricksZone


The US government deletes more than 50 years of early data on forest fires in order to make it look like forest fires are more widespread, and linked to CO2. Should be Investigated under the RICO Act. 

There’s a reason why Smokey the Bear has been around more than 75 years with his message. “Only you can prevent forest fires.” The US government had known for decades that forest fires were a serious problem – much more serious than today.

They have forest fire data going back over 100 years. But suddenly, since January of this year, the US government is acting like there had never been a Smokey the Bear before 1983 and that forest fires are just a recent problem caused by manmade climate change.

It’s all a fraud, explains data analyst and software expert Tony Heller in his latest video.

UAH Global Temperature Update for May 2021: +0.08 deg. C

by R. Spencer, June 1st, 2021 in GlobalWarming


The Version 6.0 global average lower tropospheric temperature (LT) anomaly for May, 2021 was +0.08 deg. C, up from the April, 2021 value of -0.05 deg. C.

REMINDER: We have changed the 30-year averaging period from which we compute anomalies to 1991-2020, from the old period 1981-2010. This change does not affect the temperature trends.

The linear warming trend since January, 1979 remains at +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).

Antarctica wasn’t quite as cold during the last ice age as previously thought

by OREGON STATE UNIVERSITY, June 6, 2021 in WUWT


CORVALLIS, Ore. – A study of two methods for reconstructing ancient temperatures has given climate researchers a better understanding of just how cold it was in Antarctica during the last ice age around 20,000 years ago.

Antarctica, the coldest place on Earth today, was even colder during the last ice age. For decades, the leading science suggested ice age temperatures in Antarctica were on average about 9 degrees Celsius cooler than at present.

An international team of scientists, led by Oregon State University’s Christo Buizert, has found that while parts of Antarctica were as cold as 10 degrees below current temperatures, temperatures over central East Antarctica were only 4 to 5 degrees cooler, about half of the previous estimates.

The findings were published this week in Science.

“This is the first conclusive and consistent answer we have for all of Antarctica,” said Buizert, an Oregon State University climate change specialist. “The surprising finding is that the amount of cooling is very different depending on where you are in Antarctica. This pattern of cooling is likely due to changes in the ice sheet elevation that happened between the ice age and today.”

Understanding the planet’s temperature during the last ice age is critical to understanding the transition from a cold to a warm climate and to modeling what might occur as the planet warms as a result of climate change today, said Ed Brook, a paleoclimatologist at OSU and one of the paper’s co-authors.

India, Australia, China, Russia pushing ‘massive’ coal expansion

by Ians, June 5, 2021 in Energyworld


Coal producers are actively pursuing 2.2 billion tonnes per annum of new mine projects around the world, a growth of 30 per cent from current production levels, a new report from Global Energy Monitor said on Thursday.

The first-of-its-kind analysis surveyed 432 proposed coal projects globally and found a handful of provinces and states in China, Russia, India, and Australia are responsible for 77 per cent (1.7 billion tonnes per annum) of new mine activity. If developed, these proposed projects boost supply to over four times the 1.5 degrees Celsius-compliant pathway necessary to meet the goal of the Paris climate agreement.

While three-fourths (1.6 billion tonnes per annum) of proposed coal mine capacity is in the early stages of planning and thus vulnerable to cancellation, the report finds one quarter (0.6 billion tonnes per annum) of proposed mine capacity is already under construction. The prospect of a low-carbon transition and tighter emission policies put these projects at risk of becoming up to $91 billion in stranded assets.

CARBON CYCLE

by C. Spencer, June 7, 2021 in WUWT


The increase in 12C in the atmosphere is, in my opinion, weak evidence that the annual increases are driven only by fossil fuel sources. The atmosphere can’t tell ‘anthropogenic’ carbon dioxide from natural carbon dioxide. It seems unlikely that a source that represents only about 4% of the total flux is going to drive the system. The oceans sequester the vast majority of the carbon. One would expect that warming oceans (from whatever forcing) would increase the rate of out-gassing in mid-latitudes, and decrease the rate of extraction at high-latitudes. It seems more reasonable to me that, in a world with warming oceans, there would be a shift in the relative amounts of carbon in the oceans and the atmosphere. That would be the case even in the absence of any anthropogenic carbon.

The Manichean Mann

by M. Hulme, June 2021 in IssuesinSci&Techn


Michael Mann has been in the climate wars for well over a decade now. As he reminds us frequently in this new book, he has been in the crosshairs of his enemies, has fought off the attack dogs, and carries the scars of battle. Even the environmentalist Bill McKibben’s promotional puff for the book valorizes Mann in terms of his “scars from the climate wars.” The military framing of climate change long predates Mann’s involvement, but it certainly is a framing he has done much to promote through his blogs, tweets, and general persona-at-large in public discourse.

And so it is not surprising that Mann’s new book continues his characterization of the politics of climate change through a series of complex military tropes and metaphors. Wars, battles, attacks, fights, and enemies litter its 260 pages. Much of what I said about Mann’s combative militancy in my review of his 2012 book, The Hockey Stick and the Climate Wars: Dispatches from the Front Lines, can be equally applied to this new one. Now, his central argument is that there is a new war afoot. The old war—fought mostly around the claims of climate scientists—has been (largely) won. But a new war has been ignited; Mann and his allies are now having to fight against the forces of inaction.

Mann is half right in his diagnosis. The main axes of public dispute and argumentation about climate change have changed. The politics of climate change manifest differently now than they did a decade ago. More centrally in focus—and this is a good thing—are the substantive and pressing questions about the sorts of actions, policies, and interventions that are needed, appropriate, and effective to attenuate the risks of a changing climate. What are their respective costs and benefits? How do different options interact with diverse cultural values and collide with vested interests? How do they complicate international geopolitics?

So in this observation Mann is correct. The focus of the issue has moved from “is there a problem?” to “what should be done about it?”
