Global Warning/Climate Change

And every aspect of our weather is affected by the 1C of global warming caused by human activities. While no weather event can be blamed solely on human-driven warming, none is unaffected by it.

We know that the severity and impact of hurricanes on coastal cities is exacerbated by at least two factors: higher sea levels, caused primarily by the thermal expansion of seawater; and greater storm intensity, caused by higher sea temperatures and the ability of warm air to hold more water than cold air.

Before it reached the Gulf of Mexico, Harvey had been demoted from a tropical storm to a tropical wave. But as it reached the Gulf, where temperatures this month have been far above average, it was upgraded first to a tropical depression, then to a category one hurricane. It might have been expected to weaken as it approached the coast, as hurricanes churn the sea, bringing cooler waters to the surface. But the water it brought up from 100 metres and more was also unusually warm. By the time it reached land, Harvey had intensified to a category four hurricane.

We were warned about this. In June, for instance, Robert Kopp, a professor of Earth sciences, predicted: “In the absence of major efforts to reduce emissions and strengthen resilience, the Gulf Coast will take a massive hit. Its exposure to sea-level rise – made worse by potentially stronger hurricanes – poses a major risk to its communities.”

So which expert should we listen to?

Pretty much.

Here's a map of the Gulf surface temperature anomaly on August 23. This does not account for the warmer deeper water that my previous quote said was a major factor.

So which expert should we listen to?

Maybe the vast majority that agree with one another?

I think that's what literature reviews and scientific associations are for. They can wade through the mountains of evidence, they have the expertise and resources to do it.

Well, that's the other alternative.

Last I read, it's really not clear whether global warming increases the frequency of hurricanes, but there's growing evidence that it makes them stronger and more destructive. Not enough evidence to consider it conclusively proven, though.

That, of course, is my memory of what I read earlier, without referencing anything a scientist would take seriously. So do your own reading ;->

Maybe the vast majority that agree with one another?

Like those who believed in Eugenics?

Like those who believed in slavery?

Like those who believed in a flat earth?

I really do think you have to look at the strength of the arguments on either side. And for this kind of thing, I suspect few of us have the time or expertise to do that. Most of the time, this issue is a stand-in for political views.

Not much point to disputing it if we aren't going to get into the details of the scientific argument, though. It turns into hitting each other over the head without saying anything meaningful.

The context was scientific expertise. Look at peer reviewed studies.

Slavery is not a scientific question. Flat earth has not been the position of science since classical Greece. Eugenics? There may scientific backing for the theory, but they forgot to apply biblical morality.
