Climate change is supercharging the water cycle

[watsup]

Climate change is supercharging the water cycle, bringing heavier precipitation extremes — and related flood risks — across the U.S.

As the climate has warmed from 1958 to 2021, the most extreme precipitation days have intensified in every major U.S. region, led by the Northeast (+60%) and Midwest (+45%).

This hazardous intensification is expected to continue with future warming.

High future levels of extreme precipitation intensification are concentrated in: Alaska, Hawaii, Tennessee, Alabama, Georgia, Mississippi, Maine, North Carolina, and Kentucky.

People, ecosystems, and infrastructure in both wet and dry locations are facing the risks that come with short bursts of extreme rainfall.

Climate change is bringing heavier rainfall extremes and increased, inequitable flood risk to many parts of the U.S.

For every 1°F of warming the air can hold an extra 4% of moisture, increasing the chances of heavier downpours that contribute to the risk of flash floods.

Heavy downpours bring more rain, faster — causing flash flooding and landslides that can displace families, drown crops, damage infrastructure, and expose people to hazardous debris, contaminants, and water-borne disease.

In the U.S., extreme daily rainfall has become more frequent since the 1980s. Hourly rainfall intensity has also increased since 1970 — by 13% on average across 150 U.S. locations analyzed by Climate Central.

As the climate has warmed over recent decades, the most extreme precipitation days have become more intense across the U.S.

As precipitation extremes intensify, the wettest days each year bring increasing flood hazards. And this intensification trend has been widespread.

In the Northeast and Midwest, the amount of precipitation falling on the heaviest 1% of days has increased 60% and 45%, respectively, from 1958 to 2021 according to the Fifth National Climate Assessment.

The heaviest rainfall events have become wetter across all other major regions of the continental U.S. from 1958 to 2021 as well, led by: the Southeast (+37%); the Northern Rockies and Plains (+24%); and the South (+21%).

Bottom line: we are already experiencing the extreme negative events resulting from global warming/climate change, and it is predicted to only get worse.

Three key points: extreme precipitation in a warming climate​

1. For every 1°F of warming, the air can hold an extra 4% of moisture.

This relationship between air temperature and water vapor pressure is governed by the laws of thermodynamics and represented in the Clausius-Clapeyron equation.

2. More moisture in warmer air increases heavier downpours.

Theory suggests that rainfall becomes more intense with warming. Both rain gauge data and modeling experiments support this theory.

• Globally, the frequency and intensity of heavy rainfall events have increased since the 1950s, largely due to human-caused climate change, according to the latest reports from the Intergovernmental Panel on Climate Change.
• In the U.S., extreme daily rainfall events have been on the rise since the 1980s.

3. Intensifying rainfall due to climate change has cost the U.S. billions in inland flood damages over the last three decades.

Inland flooding in the U.S. caused $230 billion in damages from 1988 to 2021. Over one-third (37%) of those damages are attributed to precipitation changes due to climate warming.

• That’s $84 billion in past flood damage due to warming-induced rainfall intensification. And the most intense downpours have caused the largest damages.

How is it that the deniers either don’t know or ignorantly refuse to acknowledge these basic concepts of the connection between increased heat in the atmosphere and its effects on rain clouds?

 

[Mach]

In reading about Climate change, to refute the usual deniers, it's pretty spooky stuff.
They do not know what's worst case...
They do not know what is the point of no return, or what positive feedback loops might unwind for decades, or centuries, after we try to correct our atmospheric conditions.

I predict a day when insurance companies will no longer offer flood insurance in many areas. Some major insurance companies have already pulled out of Florida altogether when it comes to property insurance.

We're already in the find-out stage of feedbacks. The boreal forests keep burning, and as they do, they pump lots of CO2 into the atmosphere.

As the floods in New England have shown, this isn't just a coastal problem.

Well, get off the computer and do something about it. All everyone does is talk. This so called climate change will not be something any of us will be able to control. Throwing money in the wind.

The idea of a point of no return or warming in the pipeline is not supported by the very science that predicts the high climate sensitivity.
There were two studies related to this topic, where they used the climate simulators used to find ECS, to look at smaller pulses,
like the kind Human activity causes.
Maximum warming occurs about one decade after a carbon dioxide emission
The time lag between a carbon dioxide emission and maximum warming increases with the size of the emission
The graphic in the second study says it all.

A 100 GtC pulse is like a single year increase of 47 ppm, about 20 times greater than normal growth,
yet maximum warming was reached in a decade, and did not go higher for 1000 years in the simulation.
This means that the only warming in our future is what remains of the emissions of the last decade, AND any future emissions.

As for the feedback loops, those to are in the simulations, but let's consider that most of the melting of the ice sheets has already happened,
and as you get further North or South, the lower angles have less effect.
Keep in mind that the Sun at the North and South poles only gets to a maximum of 23.5 degrees high, so
surfaces like the ocean reflect almost as much light as snow or ice.

Unfortunately modern technology and a strong demand for housing has pushed development to places that
may not be sustainable with current construction methods.
People want to live on the water, but that may not be compatible with insurance companies ideas of risk.
Flood insurance is a different animal as it is federally subsidized, but standard homeowners policies are required if
mortgages are to be available in an area. No homeowners insurance very likely no mortgages.
If no one can sell property, the prices will fall until only people who can buy the property outright will be
able to purchase it.

The precipitation expected tomorrow isn't extreme in quantity, but it is in type.

Temps to drop in Reno Friday; snow possible in the mountains​

Snow in August is unheard of, at any elevation.

You want us to do something about a thing you claim we can't do anything about? Maybe you should clarify.

You may want to read this study. It correlates the extra precipitation with the Urban growth. It appears they found a correlation between city locations and precipitation.

This research reports a global analysis of urban precipitation anomalies encompassing over one thousand cities worldwide. While earlier studies have focused on the impact of urbanization on precipitation for specific cities or isolated thunderstorm cases, our research breaks innovative ground by mapping global urban precipitation hotspots over the past 20 y. This study provides global evidence of noticeable urban precipitation anomalies, especially in hot and humid climates. Beyond the anticipated influence of local climate, our findings reveal that higher levels of urbanization enhance these urban precipitation anomalies. This research not only deepens our understanding of how cities shape precipitation but also establishes the groundwork for incorporating urbanization considerations into future precipitation projections.​

From the article: “We find that more than 60% of the global cities AND THEIR DOWNWIND REGIONS are receiving more precipitation than the surrounding rural areas.”. All that this is really saying is that the heat from urban areas enhances the intensity of thunderstorms which results in more moisture being developed and eventually being sent back to Earth as rain and the increased potential for flooding. Not all thunderstorms pass over urban areas, and yet gain strength as a result of additional heat in the atmosphere due to global warming/climate change. That is the point of this thread.

Duh...

You do not see how it destroys your argument. Do you.

 

[watsup]

Duh...

Kind of blows your argument away.

Just the opposite. It shows that heat increases the strength of thunderstorms. That would also include atmospheric heat on an overall basis, not just that associated with urban areas.

 

[Gordy327]

Well, get off the computer and do something about it. All everyone does is talk. This so called climate change will not be something any of us will be able to control. Throwing money in the wind.

So your solution is to do nothing at all?

 

[Lord of Planar]

Just the opposite. It shows that heat increases the strength of thunderstorms. That would also include atmospheric heat on an overall basis, not just that associated with urban areas.

You do not get it. The heat signatures are different.

 

[Lord of Planar]

Not only are the heat signatures different, but the aerosols from diesel emissions and other pollutants rise with the heat. Don't you remember what I said about how aerosols affect cloud formations and precipitation?

Probably not, as you deny any science that is not in your Bible.

 

[Lord of Planar]

So your solution is to do nothing at all?

Why do something about an imaginary problem?

CO2 is not the problem. Actual pollutants we inject into the air like soot are the problem. The agenda is focusing on fiction instead of reality.

CO2 is also a pollutant byproduct of combustion, industry, and such. But the real problem I'd overpopulation. Climate change, pollution, and such issues are simply a symptom and consequence of that problem.

 

[Lord of Planar]

CO2 is also a pollutant byproduct of combustion, industry, and such.

Wrong. CO2 is a product of energy production, but older methods have pollutants as a byproduct. CO2 is a necessary gas for all life on earth. The biosphere loves more of it. We are making the planet greener by our CO2 emissions.

But the real problem I'd overpopulation.

That is a different problem. But more CO2 will help with growing more crops for a larger population.

Climate change, pollution, and such issues are simply a symptom and consequence of that problem.

I see you are lacking in science but indoctrinated rather well.

Can you show me explicit scientific evidence that more CO2 is harmful?

Plant life can only absorb so much CO2 at a time. With increased deforestation, the total amount absorbed drops and CO2 concentrations rise. It's the proverbial "too much of a good thing." Except too much CO2 is not a good thing, especially in terms of the greenhouse effect. Science is on side on this one.
