Of 21 Winter Olympic Cities, Many May Soon Be Too Warm to Host the Games | New York Times

Distill the upcoming Winter Olympics in Pyeongchang, South Korea, to their essence and you get 15 sports that involve gliding on snow or ice. Because of climate change, though, by 2050 many prior Winter Games locations may be too warm to ever host the Games again.

 

Weather.com devoted its entire site to climate change today. Here’s why. | Washington Post

It’s a 50-state project, and it’s the only thing you’ll see on Weather.com today — stories from New England to Hawaii on how people and ecosystems are adapting (or failing to adapt) to climate change and the new, extreme weather that comes with it. All 50 stories are part of the website’s series called “United States of Climate Change.” There are long-form stories, some investigations, videos and photos, rolled into one project to “communicate the reality of climate change across the country.”

“People across the U.S. are quietly living the impacts of climate change,” Gilderman said. “The general public is searching for credible information on what is (but shouldn’t be) a contentious subject.”

 

Geo engineering plans to cool the Earth are sparse and very low scale.

This is one that has been around for years, and continues to have research done on it.

Professor Stephen Salter has been developing plans for wind powered automatic sail boats, that would create bright clouds to reflect sunlight. The idea came from the "contrails" created by shipping in the Atlantic.

Since the temperature over the US increased when the 9/11 flight bans were active, it appears that reflected heat from the Sun can be effectively blocked by clouds.

Cleaning Up Air Pollution May Strengthen Global Warming | Scientific American

In a study reported in the journal Geophysical Research Letters, pollution in the atmosphere is having an unexpected consequence — it's helping to cool the climate, masking some of the global warming that's occurred so far. Eliminating the human emission of aerosols—tiny, air-polluting particles often released by industrial activities—could result in additional global warming of anywhere from half a degree to 1 degree Celsius.

Aerosols don't linger in the atmosphere for very long, meaning they don't have time to spread around the world the way carbon dioxide and some other greenhouse gases do. Their effects tend to be strongest in the regions where they were emitted in the first place. This means the places where air pollution is most severe are likely to experience some of the greatest effects if that pollution were to disappear. East Asia, where aerosol emissions are some of the highest in the world, would be likely to experience a strong increase in precipitation and extreme weather events.

 

If we start deliberately cooling the Earth, we may not be able to stop | The Verge

In a study published in the journal Nature Ecology & Evolution, researchers used models to predict what would happen if we sprayed the aerosols for 50 years, and then abruptly stopped. They found that this scenario would cause the Earth to warm up too quickly to give animals time to move to more comfortable environments, leading to a huge loss of plant and animal species. The effects would be two to four times worse than with global warming alone.

 

Two things...
A huge amount of mercury has been found in the Arctic, that will be released (along with massive amounts of carbon dioxide, methane and biological pathogens from the antiquities) as climate change melts the permafrost. Every one who relies on water and food will be affected, but otherwise there should be little impact.
The ozone hole in the upper stratosphere over Antartica has been closing for decades, but the lower stratosphere ozone levels over the tropics has been declining for just as long, resulting in a net loss of ozone.
The current policy of complete denial and abundant prayer should solve both problems, whilst short term profit taking will continue unabated.

 

Wow, just looked it up -

Apart from the Arctic potential, I discovered someting I was never aware of - we make a lot of Mercury ourselves

Melting Arctic Permafrost Could Release Tons of Toxic Mercury https://news.nationalgeographic.com/2018/02/melting-arctic-permafrost-toxic-mercury-environment/

I guess that's why game fish are inedible -

 

It turns out this isn't so wise.

 

I started to post the "positions" on climate change of each news organization showing who believed and who didn't, but then figured why bother? Everyone knows how it turns out.

 

Research team detects an acceleration in the 25-year satellite sea level record | PHYS.org

Global sea level rise is not cruising along at a steady 3 mm per year, it's accelerating a little every year. The rate is increasing by about 0.08 mm/year every year—which could mean an annual rate of sea level rise of 10 mm/year, or even more, by 2100. This acceleration is driven mainly by accelerated melting in Greenland and Antarctica. It has the potential to double the total sea level rise by 2100 as compared to projections that assume a constant rate—to more than 60 cm instead of about 30.

 

Is civil disobedience an effective response to global warming inaction?

Goodbye, deep sea hydrothermal vents, we hardly knew ye.
This is why we can't have good stuff.

Mining companies worldwide are set to start pulverizing the Earth's hydrothermal vents, so's they can grub out the concentrated heavy metals, rare-earth metals, precious metals and any other profitable stuff they can then use to make more doo-dads for us.
World's first deep sea mining robot waits for the go ahead https://gadgets.ndtv.com/science/news/worlds-first-deep-sea-mining-robot-waits-for-the-go-ahead-510407

These vents are the actual 'Gardens of Eden' so to speak. Abiogenesis - Wikipedia https://en.wikipedia.org/wiki/Abiogenesis#Deep_sea_vent_hypothesis

The earliest known life forms on Earth are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 billion years ago, not long after the oceans formed 4.41 billion years ago, and not long after the formation of the Earth 4.54 billion years ago.

 

When one Flies to a far away destination for Ecotourism, then Heli fishing is a must do too of course . . . ​

Wow, you KNOW you have too much money when you use a gas guzzling $600 and hour machine to hunt a kilo of animal meat worth $26 per kilo.

Is it worse than hunting Giraffes and Lions. ?

Then there are people going to jail for their grandkids - turning off oil pipelines.
