Climate change denial has made numerous headlines in recent weeks. David Rose stated in The Daily Mail that there has been a global warming hiatus covered up by dubious science, Bret Stephens criticized the certitude of evidence in The New York Times, and Trump is rapidly making decisions based on his belief that humans have not impacted climate change.
David Rose’s claim in The Daily Mail that “we now know that [there is a climate change hiatus] for a fact” is based on “the bravery of a whistleblower” who purportedly revealed that the data from a 2015 NOAA Study is flawed due to it being adjusted upwards.
This claim is debunked in two ways. Firstly, this manipulation is reasonable due to the history of the methods used to measure sea temperatures. Up until fairly recently, ships have been used to measure water temperatures, but their results are skewed by the engine room warming the water. The reason for the adjustment was so that the new and superior data taken from buoys and floats could be compared to the figures gathered from these ships.
Secondly, John Abraham pointed out in The Guardian that Rose’s whistleblower never worked on data, and highlighted that Rose did not mention that the study had been independently verified.
Donald Trump has insisted throughout his campaign that climate change is not caused by humans, and more specifically that CO2 does not cause global warming, a claim which has been bolstered by Scott Pruitt, Administrator of the Environmental Protection Agency, since he arrived in the White House.
This has also been disproved by numerous studies and a deluge of research, as is shown by the composite of figures on skepticalscience.com (a website that is highly worth looking through on other climate change related topics):
“CO2 and other greenhouse gases keep the Earth’s surface 33°Celsius (59.4°F) warmer than it would be without them. We have added 42% more CO2, and temperatures have gone up […] According to an ongoing temperature analysis conducted by scientists at NASA’s Goddard Institute for Space Studies (GISS)…the average global temperature on Earth has increased by about 0.8°Celsius (1.4°Fahrenheit) since 1880. Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.15-0.20°C per decade.”
In order to slow climate change, action can be taken on two fronts: challenging claims such as the examples presented above and developing international systems to combat climate change.
The response to Bret Stephens’s article was vitriolic but it was logical, justified, and supported by facts. While we must fight in the same arena, it is crucial that we use weapons other than undermining truth, manipulating the public through disinformation, and cherry-picking facts. A group of climate scientists responded perfectly by penning an open letter in response, which culminated with the line “it must be made clear that there are facts that are not subject to opinion.” These facts must be made known.
