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:

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.

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).

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.

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.

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.
