Reality CheckAccording to a preliminary report released by the Intergovernmental Panel on Climate Change (IPCC), there will be no detectable influence of mankind’s influence on the Earth’s weather for at least thirty years; perhaps not until the end of this century. The Summary for Policymakers of the Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation, is in stark contrast to other statements made by the IPCC. It shows that mankind’s influence on the weather is far smaller than natural factors. Surveying the state of scientific knowledge IPCC scientists say they cannot determine if mankind’s influence will result in more, or fewer, extreme weather events over the next thirty years or more. Even making the questionable assumption that our computer models are good enough to predict what will happen in the future, for projected changes by the end of the 21st century, the uncertainties in those computer models, and the range of natural climatic variability, are far larger than any predicted human-influenced effects. Extreme weather events have always been with us, and will continue to be so. It is the international community's responsibility to make those likely to be subjected to them become more resilient. |
