“Oklahoma is burning, both literally and figuratively,” the state’s climatologist reported Monday, as temperatures soared into the triple digits and draught-stricken grasslands provided tinder for wildfires in several counties. The western part of the state faces the worst of the heat wave; grab the panhandle, and it will singe your palm. In Oklahoma, this is supposed to be the wettest part of the year.
“I don’t know what to tell ya,” the climatologist wrote. He linked to a state drought map from May of 2011, which shows similar swaths of red in the west. “Look familiar?”
Across the United States, the abnormal has become a new normal. “Climate change, once considered an issue for a distant future, has moved firmly into the present,” scientists affirmed in the National Climate Assessment, a congressionally mandated report released on Tuesday. Its authors found that climate disruption is already evident in every region of the country.
Although scientists caution against chalking up each aberrant event like the Oklahoma heat wave to climate change, such extremes are consistent with the severe weather and seasonal disruptions they anticipate in the future. The flip side to the longer periods of hot temperatures and drought that have been documented recently is a noted increase in heavy downpours, particularly in the Northeast, Midwest and upper Great Plains. The temperature is gradually rising, and air holds more moisture as it warms; it is then released in heavier rainfalls. In September, a year’s worth of rain flooded through parts of Colorado in a week. In April, workers in Washington State spent 38 days looking for bodies in the debris left by a massive landslide.
The costs of a changing climate are staggering. Weather disasters with billion-dollar price tags have occurred in many states in recent years but with particular frequency in the Southeast, Texas and Oklahoma. Agricultural losses from the 2011 drought in Oklahoma and Texas alone amounted to more than $10 billion. In 2012, a late-spring cold snap after a warm winter caused $200 million in damage to Michigan’s cherry industry. The damage from Hurricane Sandy is thought to have exceeded $65 billion. Hurricane winds and rising seas cost Gulf Coast states $14 billion a year. By 2100, a four-foot rise in sea levels will cause $325 billion in damage nationally, with destruction in Florida alone totally $130 billion.
The climate toll is also born by bodies, and some more than others. “Certain people and communities are especially vulnerable, including children, the elderly, the sick, the poor and some communities of color,” reads the report. Heat, drought and wildfires worsen air pollution and respiratory stress, and scientists expect more emergency room visits and early deaths. The risk of waterborne diseases is rising along with rainfall and flooding. Diseases transmitted by fleas, ticks and mosquitos are spreading as climatic shifts make new regions hospitable to the carriers. More people will die from heatstroke and from the effects of extreme heat on other conditions like heart disease.
These details are familiar to anyone who has paid attention to climate reports over the years, although their calls for action have grown increasingly dire. “Adaptation and mitigation are closely linked; adaptation efforts will be more difficult, more costly, and less likely to succeed if significant mitigation actions are not taken,” the report warns. “Although some additional climate change and related impacts are now unavoidable, the amount of future climate change and its consequences will still largely be determined by our choices, now and in the near future.”
