Attribution Science Affirms Climate Change Impacts
Climate change is real. Welcome to the new normal.
Eugene Robinson, September 17, 2018 (Washington Post)
“…Tropical cyclones are nothing new, of course. But climate scientists say that global warming should make such storms wetter, slower and more intense — which is exactly what seems to be happening…Climate change is a global phenomenon…Every human being on the planet has a stake in what governments do to limit and adapt to climate change…[S]cientists are now cautiously making the first serious attempts to gauge the impact of climate change on specific weather events such as storms, monsoons, droughts and heat waves…The most ambitious attempt to quantify the link between climate and weather — a blue-chip international consortium called World Weather Attribution — has not yet made an attempt to estimate any possible effect that global warming may have had [this year’s storms…[But] the Climate Extremes Modeling Group at the Stony Brook University School of Marine and Atmospheric Sciences, estimated Sept. 12 that Florence would produce 50 percent more rainfall than if human-induced global warming had not occurred…[W]armer water is more easily evaporated, which means there is more moisture available to fuel a storm…and to be released by such storms as rainfall…
If humankind suddenly stopped burning fossil fuels tomorrow, we would still have to adapt to the climatic changes we have already set in motion. The excess carbon dioxide we have pumped into the atmosphere will remain there for thousands of years. We will be coping with massive tropical storms, tragic coastal and riverine flooding, deadly heat waves and unprecedented wildfires for the rest of our lives…[W]e should be trying to reduce carbon emissions and keep global warming to a manageable level. With the landmark Paris agreement, the nations of the world agreed to try. But [the current] administration has already proposed weakening restrictions on carbon emissions from automobiles and coal-fired power plants. And last week, there were reports that the administration also wants to loosen rules governing the release of methane, which traps even more heat than carbon dioxide…Climate change is no longer theoretical. It is real…” click here for more
