Climate change news

Sea surface temperatures and Arctic ice melt

Some interesting pieces on the time lag between cool water in the Pacific, with an origin in the Southern Ocean, and its appearance in the Arctic Ocean, at and at where EM Smith says the pop and drop point was in 1998/2000 but the time lag for the Arctic is not until 2016 - still a few years away.

The Medieval Warm Period - a ticking bomb?

At (May 2nd) we had the news a few days ago that the medieval warm period has been found in southern Europe and climate scientists that have insisted it was a purely NW European phenomenon have been telling the proles porkies. At ... a new technique for reconstructing paleo-climatic data has been applied in the Antarctic and has picked up on a fairly recent climate fluctuation, the medieval warm period.

Why are there two sides to the climate debate?

Part of the answer may lie in a post at and the focus is a couple of reviews of a book, Jonathan Hailt, The Righteous Mind: Why Good people are divided by politics and religion (see also or even

Is it really that simple?

At ... can it be that ocean heat crossing the equator influences global warming? The source appears to be Bob Tisdale at monthly updates to Sea Surface Temperatures - see menu on RH side. Tisdale appears to be saying that Hansen's models are junk, his extrapolation of North Atlantic temperatures into the Arctic is mickey mouse science, and the NASA GISS global temperature data (under the guidance of Hansen and pals) is likewise, bunkum.

Weather freaking ... the in vogue meme

The hot spell in central and eastern US in March was caused by warm air from the Caribbean blown northwards by a high pressure system blocking over North America. It was cold on the western seaboard, with a lot of wintry weather in the NW. In Australia the town of Townsville in Queensland was struck by a tornado. Residents described seeing 'green lightning' and hearing a roar 'as loud as a jet plane'. Over 20 inches of rain fell in a few days - on top of what has already been a very wet year (as a result of La Nina).

Science in desperation?

At ... we are told, with a trifle of Auntie's biased glee, rising co2 may have been, in part, responsible for the end of the last Ice Age. Has desperation set in we may wonder as various geologists, Plimer springs to mind, have pointed out unceremoniously over the years that co2 invariably lags behind rising temperatures. The paper in question has just been published by Nature (behind a pay wall) and appears, at face value to the news blurb, to be an attempt to say this is not always so.

Cosmic Dust

'Cosmic Dust in the Terrestrial Atlmosphere' was the focus of a meeting at the National Academy in Manchester on March 30th. An EU research grant has been provided to investigate the cosmic dust impact over the next five years (scientists from Leeds University, from Germany and from the US are involved). See blog April 4th and and the Royal Astronomical Society web site. The project was mentioned a few days ago but cosmic dust is clearly a very important component of climate change - or it might be.

Scaring the Proles

Poetry and climate science pragmatism ... see is the piece that comes from Sleepalot, the pseudonym of one of the commenters at the site.

Monsoon track across India

Fascinating piece at ... a paper in Geophysical Research Letters, 'Holocene Aridification of India' is based on a sediment core extracted from the Bay of Bengal where the Gondavari River drains the central Indian peninsular over which monsoon wind carry most of the precipitation. A 10,000 year reconstruction of climate in central India came about as a result of this core (close to a river mouth where it accumulates sediment very fast).

End of Holocene conjecture

An excellent piece by guest poster William McClenney at which is an update on an earlier posting. His argument is that CAGW people are ignoring the fact we live in an interglacial and we are nearing its end - or are we? Five of the last six interglacials, it is claimed, lasted around half a precession cycle.
