BEST Study Finds Temperature Changes Explained by GHG Emissions and Volcanoes

riverat1 writes "The Berkeley Earth Surface Temperature studies latest release finds that land surface temperature changes since 1750 are nearly completely explained by increases in greenhouse gases and large volcanic eruptions. They also said that including solar forcing did not significantly improve the fit. Unlike the other major temperature records BEST used nearly all available temperature records instead of just a representative sample. Yet to come is an analysis that includes ocean temperatures."

    Yep, "peer reviewed". This is apparently volume 1, issue 1 of a new series of journals started by an Indian publisher that decided to simultaneously launch 53 new journals. In order to fill them, they took pretty much anything that anyone wanted to publish.

    Taking a larger set of stations would seem to mean that this study includes stations that other studies eliminated as poor-quality. For example, stations with siting issues, stations that have moved over time between rural/urban locations, stations suffering UHI in unknown amounts.

    Given the need to work in corrections for all of these quality issues, and given a pre-stated conclusion, it is very easy to make the corrections in a way that supports your desired conclusion.

    In short: not credible.

    Actually I seem to recall that gas produces far less CO2 for energy produced that coal or oil. The thing is though, that we should take this as an opportunity to move to clean energy because it is better all round. No pollution, no digging dirty great holes in the ground (and I am in Australia, we are famous for the size of our holes in the ground). Sure it will be more expensive in the short term, but maybe that reflects the TRUE cost of energy, and you can bet your bottom dollar that it will plummet in price if the world made a commitment to full conversion. As a side benefit there would be huge investment into energy storage which should finally give us flying cars.

    There was a recent study on how green energy could provide all of our energy needs in Green:tech http://www.greentechmedia.com/articles/read/how-about-99.9-percent-renewables.

    Incidentally I was in Saudi Arabia in December and while I was there the king announced a US$25 billion program of investment in solar PV. He must know something we don't...

    Measurements on the great barrier reef have shown a temperature increase of 2 degrees since the 60's, and they are expecting another 2 by 2050, which is largely regarded as the temperature needed to kill it off. Already outside a reasonable range for the fauna that live in the area, which are migrating down the coast. If this were to happen over millennia the reef would probably migrate south, but at this rate of change it can't propagate quickly enough.

    "Alarmists" are often climate scientists. "Denialists" seem frequently to be corporate funded loons with no expertise in the area. But even if both sides were equally populated by people of the same calibre I would still think it was worth trying to switch to alternatives ASAP to avoid the risk.

    Think about it - if someone said "do this, or there is a 50% chance your house will burn down" you would do 'this', even if 'this' was quite expensive. After all, most people do exactly 'this' when they buy home insurance, and the chance is way lower than 50%.
