Hurricanes and global warming

The Myth That Climate Change Created Harvey, Irma

The Intergovernmental Panel on Climate Change reported in its most recent scientific assessment that “[n]o robust trends in annual numbers of tropical storms, hurricanes, and major hurricanes … have been identified over the past 100 years in the North Atlantic basin,” and that there are “no significant observed trends in global tropical cyclone frequency.”

Further, “confidence in large-scale changes in the intensity of extreme extratropical cyclones [such as ‘Superstorm’ Sandy] since 1900 is low.”

Other media outlets tying Harvey to climate change took a more measured approach.

For instance, Vox wrote that man-made global warming did not actually cause Harvey, but simply exacerbated the natural disaster by creating heavier rainfalls.

But this claim is discredited by University of Washington climatologist Cliff Mass, who after examining precipitation levels in the Gulf found that “[t]here is no evidence that global warming is influencing Texas coastal precipitation in the long term and little evidence that warmer than normal temperatures had any real impact on the precipitation intensity from this storm.”

Mass went on to explicitly refute those who attribute Hurricane Harvey to climate change:

The bottom line in this analysis is that both observations of the past decades and models looking forward to the future do not suggest that one can explain the heavy rains of Harvey by global warming, and folks that are suggesting it are poorly informing the public and decision makers. 

Politicians seeking to exploit Harvey and Irma as reasons to act on climate change would only make a bad situation worse. Climate policies and regulations designed to prevent natural disasters and slow the earth’s warming simply will not do so.

Then there is the NOAA: 

It is premature to conclude that human activities–and particularly greenhouse gas emissions that cause global warming–have already had a detectable impact on Atlantic hurricane or global tropical cyclone activity. That said, human activities may have already caused changes that are not yet detectable due to the small magnitude of the changes or observational limitations, or are not yet confidently modeled (e.g., aerosol effects on regional climate). ...

In summary, neither our model projections for the 21st century nor our analyses of trends in Atlantic hurricane and tropical storm counts over the past 120+ yr support the notion that greenhouse gas-induced warming leads to large increases in either tropical storm or overall hurricane numbers in the Atlantic.

Speaking of climate-change, remember all the alarm about how the world's glaciers were melting? Well, as it turns out, they are. And they've been melting for 400 years.

Remember, even former United Nations climate official Ottmar Edenhofer saw through the smokescreen:

"One has to free oneself from the illusion that international climate policy is environmental policy. This has almost nothing to do with the environmental policy anymore, with problems such as deforestation or the ozone hole," said Edenhofer, who co-chaired the U.N.'s Intergovernmental Panel on Climate Change working group on Mitigation of Climate Change from 2008 to 2015.

So what is the goal of environmental policy?

"We redistribute de facto the world's wealth by climate policy," said Edenhofer.

That is what "climate change" is really about: its advocates just want our money.

Hmm:

Taken from this interesting lesson.
