Back in November, UC-Berkeley physicist Richard Muller surprised a number of people when he stated at a congressional briefing that “global warming is real.”
Muller had previously been called a climate skeptic for drawing attention to what he called numerous errors in the film “An Inconvenient Truth,” but his own extensive research showed none of his concerns about climate change science to be legitimate.
In fact, according to the Huffington Post, “Muller explained how his team reached the conclusion that in the last half-century the earth's temperature has risen roughly 1 degree Celsius, a number that exceeds the conservative 0.64 degree estimate put forth by the United Nations' Intergovernmental Panel on Climate Change.” His study was partially funded by the Koch brothers, oil-industry billionaires who have, on more than one occasion, funded studies by climate change deniers. The Koch brothers have since questioned Muller’s findings.
In a December Wall Street journal editorial, Bjorn Lomborg, author of the “Skeptical Environmentalist” conceded that global warming is a real threat and will hit developing countries hardest, but states that cutting carbon emissions won’t make much change in temperature over the next 30 years. He claims that rather than continuing to work on getting nations to lower emissions, we should just set up infrastructures to deal with the resulting problems from climate change. Bjorn, whose numbers and conclusions have often been questioned by scientists, seems to be saying we should just throw in the towel and stand back while economics determines our world’s future.
A few days later, the New York Times printed an article on the warming Artic permafrost, which contains twice as much carbon as the entire atmosphere. Scientists believe that both global warming, resulting from human activity, and wildfires may be catalyzing the thawing of permafrost, which releases methane gas into the atmosphere as the ancient plants and animals that make up the frozen tundra decompose. Although it doesn’t stay in the atmosphere as long as carbon dioxide, methane gas is even better at trapping heat and will potentially make earth’s atmosphere warm at an even faster rate, thawing more permafrost, in a vicious cycle.
In the article, the experts said that “if humanity began getting its own emissions under control soon, the greenhouse gases emerging from permafrost could be kept to a much lower level.”
Skeptics are looking at the evidence and becoming believers. Science tells us that climate change is real, and is already well underway, but that we can still slow global warming by reducing carbon emissions. In other words, we shouldn’t throw in the towel.
