Global Warming And Climate Change A serious threat?

[DMan7]

More than 12 inches of sea level rise predicted by 2050.



(CNN) Widespread ice losses from Greenland have locked in nearly a foot of global sea level rise that's set to come in the near future -- and new research suggests there is no way to stop it, even if the world stopped releasing planet-heating emissions today.

The study, published Monday in the journal Nature Climate Change, found that the overall ice loss from Greenland's ice sheet will trigger at least 10 inches of sea level rise, no matter the climate warming scenarios. That's generally the same amount that global seas have already risen over the last century from Greenland, Antarctica and thermal expansion (when ocean water expands as it warms) combined.

The sea level rise from this melted ice will occur "regardless of any foreseeable future climate pathway this century," according to lead author Jason Box, a scientist with the Geological Survey of Denmark and Greenland. "This water is technically already under the bridge."

While the authors did not specify a timeline, they predict that the change in sea levels can occur between now and the end of the century.

This is a separate finding indicating that the sea level rise due to Greenland icesheet melt cannot be abated.

The findings come on the heels of a 2022 sea-level rise report released earlier this year by the National Oceanic and Atmospheric Administration, which found that US coasts could expect 10 to 12 inches of sea level rise in the next 30 years. This will cause high tide floods to occur more than 10 times as frequently, and allow storm surges to spread further inland, according to the report.

Greenland holds enough ice that if it all melted, it could lift sea levels by roughly 25 feet around the world. Researchers point out that a sea level rise of 20 feet doesn't mean it will rise evenly around the globe, leaving some places devastated as the sea level falls in others.

Death rate will be even lower than covid

You'll be fine. People squatting in the deep forest, shading their eyes from the sun when they finally reach a paved road will be unaffected.

Considering most of the doom and gloom predictions never came through, I don't think the problem as bad as is being exaggerated

The reason that the predictions not coming true as quickly is because there are people actively battling climate change.Do you have kids?Grandkids? Nieces and nephews? What kind of world do you want them to live in?

The changes are on a geological time scale.

And yet you will hear that emissions and such has never been higher

Heatwave in China is the most severe ever recorded in the world

A long spell of extreme hot and dry weather is affecting energy, water supplies and food production across China

Low rainfall and record-breaking heat across much of China are having widespread impacts on people, industry and farming. River and reservoir levels have fallen, factories have shut because of electricity shortages and huge areas of crops have been damaged. The situation could have worldwide repercussions, causing further disruption to supply chains and exacerbating the global food crisis.

People in large parts of China have been experiencing two months of extreme heat. Hundreds of places have reported temperatures of more than 40°C (104°F), and many records have been broken. Subway stations have set up rest areas where people can recover from the heat.

On 18 August, the temperature in Chongqing in Sichuan province reached 45°C (113°F), the highest ever recorded in China outside the desert-dominated region of Xinjiang. On 20 August, the temperature in the city didn’t fall below 34.9°C (94.8°F), the highest minimum temperature ever recorded in China in August. The maximum temperature was 43.7°C (110.7°F).

It is the longest and hottest heatwave in China since national records began in 1961. According to weather historian Maximiliano Herrera, who monitors extreme temperatures around the world, it is the most severe heatwave recorded anywhere.

“This combines the most extreme intensity with the most extreme length with an incredibly huge area all at the same time,” he says. “There is nothing in world climatic history which is even minimally comparable to what is happening in China.”

Together with the extreme heat, low rainfall in parts of China has led to rivers falling to low levels, with 66 drying up completely. In parts of the Yangtze, water levels are the lowest since records began in 1865. In a few places, local water supplies have run out and drinking water has had to be trucked in. On 19 August, China announced a national drought alert for the first time in nine years.

So we're looking at even MORE increase in global food prices and shipping?

You are correct.Green thinking is the way forward

if we lucky, yes

worst case is drought and famine

By carbon tax? Sound like a cry for.more money

[redmanjp]

we complain for 32-34C heat but places have it much worse to the point it killing ppl- moslty elderly but that dont mean it wont affect young ppl in some way- it will still make u sick if u stay in any temps 37C or higher.

a couple night ago a local weatherman say d heat index reach 45C and 48C in some places here

workmen who work outdoors, CEPEP, etc. how they would manage in such heat? do they break during the hottest time of the day? (OK CEPEP probably does go home by that time but d trest of them).

the money should go directly towards mitigating the situation- we can no longer avoid it- but we still can prevent the worse case scenario if we act now.

If it cuts emissions, great

[pugboy]

seems places that have full 4 seasons of weather getting the heat effects worse than tropical places

[redmanjp]

the irony is as it gets hotter- we consume more electricity to cool by using AC. which is the single largest consumption of power at least among residential users, thereby emitting more carbon via power plants. installing radiant barriers to keep the heat from ever reaching in the house or building can help, as well as using inverter ACs.

both of these as well as door/windows seals should have rebates- perhaps paid for by the carbon taxes. i wonder how many ppl with air-conditioned homes even think about this? even if for the purpose of lowering electricity bills? or do they just put in ah AC and done?

I need a better explanation of not only how that will happen, but what that money will be spent on

If you talking about Trinidad, that money as good as gone.Other countries may use it for its intended purpose.

More than 12 inches of sea level rise predicted by 2050.

yep. Still waiting on the dire predictions that were sposed to occur in 2000 and 2020.

The beat goes on...

I am further assured by your continued ignorance.



Climate change doubters have a favorite target: climate models. They claim that computer simulations conducted decades ago didn't accurately predict current warming, so the public should be wary of the predictive power of newer models. Now, the most sweeping evaluation of these older models—some half a century old—shows most of them were indeed accurate.

Some ignorance but mostly plain old common sense. And a healthy dose of skepticism.

we is seeing temps rising tho. hard numbers. can't argue wit numbers

Skepticism? Good..
Ignorance? Bad..

Skepticism is the cornerstone of investigation. Your "good old common sense," in the face of contrasting evidence, is simply an example of information bias. I could be wrong - but then again...

Highly unlikely. Many countries treat it as a blank cheque

Maybe so. But no one can’t state with any certainty what is the root cause behind the hard numbers.
