Well the reason why it rained for days in Houston was due to a High Pressure system sitting in Oklahoma that kept that storm from moving. It didn't have any more water than any other tropical event. Since it never moved north it sat there and fed off the gulf waters. That is all a pure natural event. hly fk. People should learn how weather develops and moves.Here's the first cult member to blame Harvey on global warming. I knew it wouldn't take long. It's difficult to exaggerate how stupid these people are:
We can’t say that Hurricane Harvey was caused by climate change. But it was certainly worsened by it.
What can we say about the role of climate change in the unprecedented disaster that is unfolding in Houston with Hurricane Harvey? There are certain climate change-related factors that we can, with great confidence, say worsened the flooding.
Sea level rise attributable to climate change – some of which is due to coastal subsidence caused by human disturbance such as oil drilling – is more than half a foot over the past few decades. That means the storm surge was half a foot higher than it would have been just decades ago, meaning far more flooding and destruction.
Harvey was almost certainly more intense than it would have been in the absence of human-caused warming, which means stronger winds, more wind damage and a larger storm surge.
The stalling is due to very weak prevailing winds, which are failing to steer the storm off to sea, allowing it to spin around and wobble back and forth. This pattern of subtropical expansion is predicted in model simulations of human-caused climate change.
In conclusion, while we cannot say climate change “caused” Hurricane Harvey, we can say is that it exacerbated several characteristics of the storm in a way that greatly increased the risk of damage and loss of life. Climate change worsened the impact of Hurricane Harvey.

Any hysterical rantings? Nope.
Was the article written by a paid Russian troll? Nope.
Was the article based on easily debunked, baseless claims? Nope.
No wonder every single conservatard on this site chimed in to offer their little "opinions."
It is an opinion piece.
While it may be true that: "In addition to that, sea surface temperatures in the region have risen about 0.5C (close to 1F) over the past few decades from roughly 30C (86F) to 30.5C (87F), which contributed to the very warm sea surface temperatures (30.5-31C, or 87-88F).
There is a simple thermodynamic relationship known as the Clausius-Clapeyron equation that tells us there is a roughly 3% increase in average atmospheric moisture content for each 0.5C of warming. Sea surface temperatures in the area where Harvey intensified were 0.5-1C warmer than current-day average temperatures, which translates to 1-1.5C warmer than “average” temperatures a few decades ago. That means 3-5% more moisture in the atmosphere.
That large amount of moisture creates the potential for much greater rainfalls and greater flooding."
It is not at all unusual for these type of storms to meander along the upper Texas coast. I've seen many tropical systems wobble in my 40 years here.
Warming may have increase the rainfall amounts slightly, imo, the affect on Harvey's path is minimal.
Harvey has dumped more rain than the three previous major hurricanes COMBINED. I hardly think your 3% increase in moisture is responsible.
My 3%? Do you understand where Mann got that figure? Harvey's path has more to do with the flooding than any other factor. I recall many storms have done that in the last 40 years.
His claim that a deep layer of warm water help intensify the storm has no reference to any study, but after all it is an opinion piece.
Study targets warm water rings that fuel hurricane intensification in the Caribbean Sea
"Tropical storms receive energy from their surrounding ocean waters. As a storm moves across the water, it may interact with rings of warm water known as eddies. As the storm moves forward over these eddies, the warm ocean waters below help fuel the storm's intensity through enhanced and sustained heat and moisture fluxes.
Similar warm ocean eddies exist in the Gulf of Mexico, a result of their separation from the warm-water Loop Current, are also of interest to the research team involved in this study.
Last year, Hurricane Matthew rapidly intensified from a tropical storm to hurricane status as it moved over the Caribbean Sea in the location where a warm ocean eddy exists, and in close proximity to where these measurements were taken for this study two years prior."

No science that Harvey carried an UNUSUAL amount of water. The entire problem wasn't the WATER CONTENT of the storm. It was the SPEED and TRAJECTORY of that storm..
Hurricane rainfall is ALWAYS MORE affected by track and speed, than a slight variation (if any) of contained water..
