when it comes to extreme weather, Mr. Trump is complicit. He plays down humans’ role in increasing the risks, and he continues to dismantle efforts to address those risks. It is hard to attribute any single weather event to climate change. But there is no reasonable doubt that humans are priming the Earth’s systems to produce disasters.Kevin Trenberth, a climate researcher at the National Center for Atmospheric Research, co-wrote a May paper showing that Harvey’s cataclysmic wetness came from the unusually hot Gulf of Mexico water that fed the hurricane before it slammed into Texas. “Harvey could not have produced so much rain without human-induced climate change,” he and his colleagues concluded. Now Florence is feasting on warm Atlantic Ocean water. “The ocean is warming up systematically,” Mr. Trenberth said, explaining that, though natural variation can turn surface temperatures up or down a bit, the oceans’ energy content is inexorably rising. “It is the strongest signal of global warming,” Mr. Trenberth added.Scientists also warn that climate change may be slowing the wind currents that guide hurricanes, making storms more sluggish and, therefore, apt to linger longer over disaster zones. Tropical cyclone movement has slowed all over the planet. Harvey’s stubborn refusal to leave the Houston area was a decisive factor in its destructiveness. Florence may behave similarly.
And human-caused sea-level rise encourages higher storm surges and fewer natural barriers between water and people.
With depressingly ironic timing, the Trump administration announced Tuesday a plan to roll back federal rules on methane, a potent greenhouse gas that is the main component in natural gas. Drillers and transporters of the fuel were supposed to be more careful about letting it waft into the atmosphere, which is nothing more than rank resource waste that also harms the environment. The Trump administration has now attacked all three pillars of President Barack Obama’s climate-change plan.
The human advancement haters rally their troops for yet another DO SOMETHING NOW! moment based on a drive-by mishmash of complex data predicated on the notion that a US president's top priority ought to be pushing post-American society to drastically alter its way of life.
How you get human advancement hating out of legitimate scientific inquiry is beyond me. There is definitely something happening here on Planet Earth and we don't know for sure what it is. So leave it up to humans to politicize it. Saving Big Coal is human advancement?
ReplyDeleteBecause oil and coal have made possible everything from air conditioning to space travel to well-lighted operating rooms.
ReplyDeleteThe advancement-haters hate freedom, too. Given the chance, they'd pass laws about how we can set our thermostats. They've already made car and truck companies comply with CAFE standards.
ReplyDeleteAt least some of the emissions standards have indeed resulted in cleaner air at least.
ReplyDeleteIt was government telling private organizations how to make their products. Always bad and wrong.
