It’s tragic that we have to continually re-establish what has already authoritatively been well-established by an abundance of data.

However, what’s significant here is that a well-know climate skeptic is finally convinced that climate change is a fact.

Climate change is real, study says

by Boonsri Dickinson

Rising land temperature is real, according to a study. A climate skeptic has conduced several studies looking into temperature data collected by weather stations over the past half-century and has concluded that climate change is real.

Average Global Temperature

To be clear, the findings discussed below haven’t been peer-reviewed.

Phil Plait at Discover magazine reiterates the early nature of the papers:

Because of that, the results need to be taken with a grain of salt. However, due to the nature of the study’s foundation and funders, which I will get to in a moment, the results are most definitely news-worthy.

The Berkeley group submitted four scientific papers for peer review and expects it to be part of the body of work in the next IPCC report on Climate Change.

The Berkeley Earth Project (BEP) looked at land temperature since the mid-1950s. Berkeley Earth’s founder and director Richard A. Muller said:

Our biggest surprise was that the new results agreed so closely with the warming values published previously by other teams in the U.S. and the U.K. This confirms that these studies were done carefully and that the potential biases identified by climate change skeptics did not seriously affect their conclusions.

Muller is a physicist at the University of California, Berkley, who had a reputation for being a climate change skeptic, says his studies back up the work of previous groups. The study used five times as many station locations: Using over 39,000 stations and combining data sets of 1.6 billion temperature reports from 16 publicly available data archives, the scientists were able to avoid station selection bias.

The Berkeley Earth Surface Temperature project was created to make sense of global temperature change, with the world’s most comprehensive set of data. Previous global warming studies by National Oceanic and Atmospheric Administration (NOAA), NASA’s Goddard Institute for Space Studies, and the Hadley Center for Climate Prediction and Research in Britain have found that global land temperature rise has increased by 1.2 degrees C from the 1900s to now.

Muller previously said in a testimony to congress in March that “based on the preliminary work we have done, I believe that the systematic biases that are the cause for most concern can be adequately handled by data analysis techniques.”

The rise in temperature since the mid-1950s, most climate scientists say, is in part due to carbon dioxide emissions from human activities.

Muller also said in his testimony that the number attributed to human caused global warming, which is around 0.6 degrees, needs to be improved. “Berkeley Earth is working to improve on the accuracy of this key number by using a more complete set of data, and by looking at biases in a new way,” he adds.

Some of the critical findings in the studies posted online include:

  • While urban land heat does occur, it doesn’t really add to the average land temperature rise.
  • Yes, a third of temperature sites reported a period of cooling over the last 70 years. This leaves the other two-thirds though, which reported warming.
  • Weather stations ranked as poor, performed just as well as the stations considered okay. Therefore, it’s alright to include poor stations in the study of global warming trends.

The Berkeley collaborators include Saul Perlmutter, who won a Nobel Prize in Physics. Using the same skills the physicist used to discover that the universe is expanding, Perlmutter and other astrophysicists and particle physicists in the group will analyze the massive weather data set.

Next, Muller wants to study the ocean temperature to build a more complete view of rising temperatures.

    i get it…if global warming is a fraud, then why on are those that firmly believe that it is fraud, why are they not demanding, protesting and so for the truth?! it seems to me that all they do is just talk about it (complain) but that is it. we need someone with guts to a movement for the truth.

  20. “Some groups of animals on the sea and land did recover quickly and began to rebuild their ecosystems, but they suffered setbacks. Life had not really recovered in these early phases because permanent ecosystems were not established.

    Professor Benton, Professor of Palaeontology at the University of Bristol, said: “Life seemed to be getting back to normal when another crisis hit and set it back again. The carbon crises were repeated many times, and then finally conditions became normal again after five million years or so.”

    Finally, after the environmental crises ceased to be so severe, more complex ecosystems emerged. In the sea, new groups, such as ancestral crabs and lobsters, as well as the first marine reptiles, came on the scene, and they formed the basis of future modern-style ecosystems.”

    Herman van Rompuy dismisses Copenhagen climate summit as ‘incredible disaster’ and expects Cancún to be no better The European Union’s new president, Herman Van Rompuy, has predicted “disaster” at the latest crucial round of global climate change negotiations in Mexico and voiced relief that he stayed away from the Copenhagen summit a year ago. on a meeting with Van Rompuy in December last year, just after he was the surprise choice to be the first president of the European council, a senior US diplomat described the Belgian as “animated and frustrated”. Van Rompuy said the Copenhagen climate change talks had been “an incredible disaster”. Looking forward to the current negotiations in Cancún in Mexico, the European leader predicted that these would be a disaster too. The US cable paints a picture of an isolated Van Rompuy.

    Political will, international talks, serious action and market changes show we are determined to rise to the challenge As things stand, the world is plainly not on track to keep the global temperature increase from climate change below 2C, which is generally regarded as global warming’s danger threshold. The UN Environment Programme (Unep) said last month that at best, current commitments would take us somewhat of half way towards a climate safe trajectory; and a World Bank published the same week showed some of the dangers of a world warmed by 4C. Anyone who engages seriously with the science is right to be concerned. But I would identify four reasons to be hopeful. First, if we act we can still climate change’s worst impacts. Both the Unep and an International Energy Agency published the week before said that time was running out, but that 2C is still within reach if we can muster the political will. Second, the international process may be slow, but…
