Climate change news

Roman Warm Period

I've posted this under climate change but it is as much history as anything else, or even geology, as the processes involved are not understood. At ... which in part is true, and in another part, untrue. The Roman Warm Period did not encompass the whole period of the Roman Empire. It was a backdrop to the rise of Rome but the climate was already deteriorating by AD230 - but the really cool weather did not set in until the 6th century AD.

The Great Dying

At ... the Great Dying is a reference to the end of Permian extinction event. As is their wont mainstream consider the culprit is down to volcanic activity - pointing a finger at the Siberian Traps, a large igneous outpouring of lava. As the Deccan Traps seem to be linked to the K/Pg boundary event, almost 200 million years later, one may wonder if an impact event also caused the Siberian Traps. At the moment old school geologists are not biting.

Antarctic Rainforest

At ... fossilised evidence of temperate rainforests only hundreds of kilometres from the South Pole has been uncovered. The warmest mean month temperature was 18.5 degrees Celsius. The discovery goes back to last year but the climate blog uses it in conjunction with another, more recent study on Antarctica. Over the last 70 years temperatures on Antarctica have not gone up - at all.

A Wonder to Behold

At ... it is bad enough that wind turbine blades cannot be recycled, and have to be cut up and placed in landfill but now it seems that an even bigger toxic problem awaits the next generation. All those earnest young activists having their bums bitten big time by the money making machine. It seems that electric vehicle batteries are going to be an even bigger problem than wind turbine blades.

A Greenland Cave

Sediments from a cave in NE Greenland tell a story. It was warm and wetter in the past. However, this is dated half a million years ago. See ... and has nothing to do with conditions during the medieval period. The big take home of the story is that NE Greenland is firmly within the Arctic as far as climate is concerned. Even a pole movement would  not alter that to any great degree. However, half a million years ago the situation was quite different. This was determined by flow stone in the cave.

White Stuff

No, not the white snow that alarmists claim we should not  be seeing as it should have come to an end. That is global warming stuff out of the sky. No, white chalk. Gary sent in a link to ... which seems to show somebody at the Guardian has swallowed a geology book on southern England. Problem is, he has missed out all the good bits. The oddities. Why is it so pristine white for example. Where has the rest of it gone and why only a bit has survived.

Holocene Hockey Stick

Coinciding with the election win by you know who we suddenly have a study that purports to show Holocene temperatures were the equivalent of the original hockey stick back in 1998, largely flat and uninteresting, apart from an  uptick at the beginning, coming out of the Younger Dryas cool period, leading up to a massive uptick in the modern world, purportedly a rise in temperature of 2.5 degrees on the early Holocene. Are the plebs being rubbered up ready for the renewables revolution? See ...

Playing Games

At ... 12 Indian meteorologists demonstrate how warming can be discovered in temperature records. Another sign that Western science is taking a back seat and the future belongs to the Chinese and the Indians. A temperature record for all of India shows no increase in net warming since 1951 or 1705 but when scientists select a cold year and draw in a red hot short term upward trend for that cold year warming miraculously appears.

How About That

Sea levels were 32m higher than today 13,800 years ago - in southern Greenland ( ) ... an embarrassment of water. Sea levels rose at a very rapid rate of knots between 12,000 and 10,000 years ago. However, they peaked at Nanotalik on Greenland by 32m above modern sea levels between the end of the Late Glacial Maximum and the Younger Dryas episode. During LGM they were at a very low ebb but rose sharply during the Bolling-Alleroed interstadial.
