Dec 03, · P olicy-makers and the media, particularly in the United States, frequently assert that climate science is highly uncertain. Some have used this as an argument against adopting strong measures to reduce greenhouse gas emissions. For example, while discussing a major U.S. Environmental Protection Agency report on the risks of climate change, then-EPA administrator The Intergovernmental Panel on Climate Change (IPCC) is an intergovernmental body of the United Nations that is dedicated to providing the world with objective, scientific information relevant to understanding the scientific basis of the risk of human-induced climate change, its natural, political, and economic impacts and risks, and possible response options Jun 29, · If climate change were a casino, we’d be hemorrhaging cash. Wildfires, heat waves, floods and superstorms, many exacerbated by climate change

In the old days, we could escape the summer heat by heading north — to climate change essays Adirondacks in the East or to the cool, forested Pacific Northwest in the West.
The climate change essays United States is currently under the influence of an epic heat dome, an expansive region of high atmospheric pressure characterized by heat, drought and heightened fire danger.
All bets are off when one accounts for human-caused warming, climate change essays. Might a heat dome have developed out West this past week without climate change? Almost surely not. If we step back a bit, we see a disturbing pattern. With this latest climate change essays wave, Canada observed its hottest day on record : degrees in British Columbia. Less than a year ago, the United States set its own record — the highest climate change essays reliably recorded on the entire planet, climate change essays, in fact — with a climate change essays reading in Death Valley in Southern California.
Yes, the dice have been loaded, and not in our favor. The science is clear on how human-caused climate change is already affecting heat waves: Global warming has caused them to be hotter, larger, climate change essays, longer and more frequent.
What were once very rare events are becoming more common. Heat waves now occur three times as often as they did in the s — on average climate change essays least six times a year in the United States in the s.
Record-breaking hot months are occurring five times more often than would be expected without global warming. And heat waves have become larger, affecting 25 percent more land area in the Northern Hemisphere than they did in ; including ocean areas, heat waves grew 50 percent.
These changes matter because extreme heat is the deadliest form of extreme weather in the United States, causing more deaths on average than hurricanes and floods combined over the past 30 years. Recent research projects that heat stress will triple in the Pacific Northwest by unless aggressive action is taken to reduce heat-trapping greenhouse gas emissions.
Some still refuse to acknowledge the dire warning that Mother Nature is sending us. They say the science is too unsettled to take action. But uncertainty, if anything, is a reason for taking even more significant action to reduce carbon emissions.
Uncertainty is not our friend. And the current heat dome is an excellent example of why. The heat wave afflicting the Pacific Northwest is characterized by what is known as an omega block pattern, because of the shape the sharply curving jet stream makes, like the Greek letter climate change essays Ω. This omega curve is part of a pattern of pronounced north-south wiggles made by the jet stream as it traverses the Northern Hemisphere.
It is an example of a phenomenon known as wave resonance, which scientists including one of us have shown is increasingly favored by the considerable warming of the Arctic. By decreasing the contrast in temperature between the cold pole and warm subtropics, the climate change essays warming of the Arctic causes the jet stream to slow down and, under the right circumstances, like the ones prevailing nowsettle into a very wiggly and rather stable configuration.
That, in turn, allows very deep high pressure centers, like the current heat dome, to remain locked in place over a region, as it is over the Pacific Northwest. Those climate models that the critics claim are alarmist do a poor job of reproducing this phenomenon, climate change essays. The choice is ours. Michael E.
