"We see clear evidence for warming in one of the most remote places on Earth at a time when the Arctic should be cooling because of natural processes."
Mr Axford is the chief author of the study published in the Proceedings of the National Academy of Sciences.
For thousands of years, environmental changes in a remote lake on Canada's Baffin Island closely matched natural, cyclical climate changes such as those caused by the Earth's periodic wobble as it swings around the sun, the researchers said.
However, lake sediment cores dating from 1950 show that expected climate cooling was overridden by human activity like greenhouse gas emissions.
Researchers were able to reconstruct the local climate over the past 200,000 years by analysing algae, insect fossils and geochemical traces in sediment cores extracted from the 40ha lake.
Interesting.
At the Institute we have been vocal about putting any faith in the Global Climate Models for many reasons - all modeling assumes one knows all the angles and all the pathways; and that is total hubris, especially as far as Earth's climatic variation. In the philosophical sense modelling is hardly science at all, but to a degree humanistic fantasy, like movies or Christmas train gardens.
In this report however if it is legitimate, and one can't dismiss PNAS, there is evidence something is recently environmentally out of whack with Earth's precessional (wobble) period. If one looks at 200,000 years of reliable periodic association then sees something incongruent, then there is apparently something unique happening.
But this statement:
However, lake sediment cores dating from 1950 show that expected climate cooling was overridden by human activity like greenhouse gas emissions.
is really ignorant and quite annoying; hopefully it wasn't the scientists who made it. It exposes the bigotry associated with the whole anthropogenic claim. There is little reason whatsoever to associate the incongruent happening to anthropogenic causes when such dramatic variations have occurred during other era's when SUV's did not exist - if of course such incongruent happenings did indeed occur when SUV's did not exist.
Which means to make any argument at all for "human activity like greenhouse gas emissions," a greater geological perspective is needed to rule out non-anthropogenic causes. That is to say no one is denying global warming occurs or that it has occurred during humanity's industrialization; but to say that industrialization is the cause of global warming is bogus until proven; and given that CO2 has been significantly higher in the geological past with its subsequent reduction and while life on Earth prospered, there is no reason to react unscientifically (as so many politicians routinely do).

That area got it's first important military outposts in the 1940’s due to World War Two. Subsequently, several military bases were extended due to the Cold War. DDT was prominently introduced to those bases to cut down on the summer swarm of mosquitoes.
DDT, introduced in the late 40's and early 50's killed the midges.
Other scientists are finding traces of DDT in the various nearby glaciers from the same time period!
