Scientists Report Climate Change Really Did Make Hurricane Harvey Worse

Groundbreaking research has found that climate change increased the likelihood and magnitude of Hurricane Harvey. According to articles published in Geophysical Research Letters (GRL) and Environmental Research Letters (ERL), Hurricane Harvey was about three times more likely to happen and up to 38% more rain-heavy because of climate change.

The scientists used two different approaches. In the ERL article, they analyzed U.S. Gulf Coast rainfall records dating back to 1880 and found that infrequent, heavy rainfall events have gotten more severe. In the GRL article, researchers looked at Houston-area weather data from 1950-2016 and climate records and came to a similar conclusion.

In the ERL, they found that Harvey’s rainfall was 15 percent higher than would be expected without climate change. In the GRL, they estimated that total rainfall was as much as 38 percent higher than would be expected in a world without global warming.

Scientists in both publications note how climate change increased the likelihood of an event like Hurricane Harvey. They noted that the odds of an event like Harvey were 1 in 3,000 years in the past; global warming has upped that to about 1 in 1,000 years. According to Geert Jan van Oldenborgh of the Royal Netherlands Meteorological Institute, “The probability of such an event has increased by roughly a factor of three.”

Climate change is a real and pressing threat. It is likely that we are not doing enough to reduce our contribution to the planetary greenhouse effect. The effects are being felt now. Polar bears are starving. Birds cannot stay at their native nesting grounds. Human health is suffering.

Hurricane Harvey was beyond devastating — it was a 1,000-year flood-event, and the human costs were significant. It has been linked to over 80 deaths, tens of thousands displaced people, and billions of dollars in damage. This is not the first time global warming has been linked to extreme weather events. But the release of these two studies is crucial because some have vocally denied the link between Harvey and global warming. Now, the evidence speaks for itself.

    Not surprising! With all these severe weather events going on, the timing couldn’t have been worse to have an ego-maniacal, arrogant, stupid, Luddite, reactionary, climate-denying, lecherous, treasonous, blockhead in the White House – and Congress, the cabinet, and the courts, filled with his evil little spineless, sniveling yes-men!!!!!!! This country and this planet are doomed unless we get these people out of office A.S.A.P., and replace them with people who will stand up to the special interests and restore our democracy!!!!!

    It’s called Bio-engineering. It’s Shadow governments. Responded weather. All this scientist info is just garbage. Please don’t waste your time on this. All
    Lies!!!i

    The summer of 2015 was the hottest summer on record in L.A. This past winter in Sydney was one of the warmest I can remember.
