Everyone is talking about the “Climate Emergency”. We are talking about “SOS” as an emergency. Many people really do not believe it is an emergency. In fact, many people probably do not think there is a problem with climate change at all. This person, for instance:
The first piece of evidence to look at is the historical rise in carbon dioxide found in ice core data. The following graph shows the atmospheric carbon dioxide concentrations in parts per million (ppm), based on EPICA (ice core) data. The peaks and valleys in carbon dioxide levels track the coming and going of ice ages (low carbon dioxide) and warmer interglacials (higher levels). Throughout these cycles, atmospheric carbon dioxide was never higher than 300 ppm; in 2018, it reached 407.4 ppm (black dot).
The next evidence shows the excess rise in global temperatures above the average temperature from 1961 to 1990 in the long-term period of 1850 to 2018. It is getting much hotter. In fact 1 degree hotter than the average. If we go much above 1.5 degrees Celsius warmer, scientists have calculated that disaster starts to happen. Temperatures are different obviously in different parts of the world. It is the direction of travel that matters.
Take a look at this report by Alan Buis from the National Aeronautics and Space Administration for the details behind the significance of 1.5 degrees Celsius warmer. CLICK HERE.
Finally, there is a group of scientists known as the “Intergovernmental Panel on Climate Change”. They have produced around 13,950 articles on Climate Change between 1991 and 2012. 13,926 of those articles were along the lines of “Houston we have a problem” as in the Apollo 13 film. As someone put it: “If 13,926 engineers told you that it was not safe to cross a bridge, but 24 did not, would you still cross the bridge?”.
