Here's a Ted talk by a glaciologist studying Greenland

Ice melt from Greenland alone will cause sea level to rise from 20cm to 1m or more in the next 80 years. Impossible to say for sure but according to the science it's going to happen.

l remember years ago seeing some Beeboid in Greenland, pontificating about a glacier having receded so far that the ruins of a Viking-era farm had been exposed, and how Global Warming was going to kill us all in ten fifteen twenty years before long, mark my words!

The only point he didn’t cover was why the glacier had retreated so far 1,200 years ago that the Vikings had been able to build a farm there in the first place.

Odd, that.

Reporting on the environment may prove lethal.

Thirteen journalists who were investigating environmental issues have been killed in recent years, according to a new study from the Committee to Protect Journalists.

The CPJ says many more journalists covering climate change are facing violence, intimidation, harassment, and lawsuits. As it investigates another 16 deaths, it believes the tally of murders may be as high as 29.

The Guardian points out that such a figure would make this field of journalism “one of the most dangerous after war reporting”.

The CJP report, entitled Green Blood, has focused particularly on the mining industry. Three journalists have died while reporting on the sector in the Phillippines.

There have also been deaths in Tanzania, which has slipped 25 places on the World Press Freedom Index produced by Reporters Without Borders. It now ranks 118th out of 179 countries.

“Journalists [in Tanzania] are attacked without reason,” Ryan Powell, a media development specialist working in Africa, said. “Police will harass journalists, and people do not interfere.”

India is revealed to be one of the most dangerous places to be an environmental journalist – three of the 13 identified as having been killed were from the country.

This is an extremely interesting question, and one that deserves to be framed from the point of view of a curious layman who knows that highly trained scientists with masses of data are likely to know better than him rather than that of a small minded man sitting in an armchair pontificating at the TV.

I know that the Greenland ice sheet is known to have both decreased and increased considerably over time, and seems to respond to relatively small changes in global temperature. So when the Norse settlers first arrived, what conditions did they find? Why was Greenland a worthwhile place for them to settle? I've read somewhere that it's thought they failed to respond to changes in climate, which is why their settlements ultimately failed. But what evidence have we that current changes in the Greenland ice sheet are due to anthropogenic climate change, and not part of an ongoing natural process? Enquiring minds want to know! Smaller minds, as ever, only care about anything as far as it supports views they've already set their hearts on. I'll do some research when I get the chance, but I suspect the answers won't be simple.

Yeti habitats under threat from climate change.

Declassified Cold War–era spy satellite film shows that the melting of hundreds of Himalayan glaciers has sped up in recent decades.

An analysis of 650 of the largest glaciers in the mountain range revealed that the total ice mass in 2000 was 87 percent of the 1975 mass. By 2016, the total ice mass had shrunk to only 72 percent of the 1975 total. The data show that the glaciers are receding twice as fast now as they were at the end of the 20th century, report Joshua Maurer, a glaciologist at Columbia University, and colleagues June 19 in Science Advances.

The primary cause for that acceleration, the researchers found, was warming: Temperatures in the region have increased by an average 1 degree Celsius from 2000 to 2016.

Meltwater from Himalayan glaciers are a source of freshwater to hundreds of millions of people each year. However, recent studies examining changes in glacier mass from 2000 to 2016 have shown that this store of freshwater is shrinking, threatening future water security in the region (SN Online: 5/29/19).

Nah: How else would Dame Emma Thompson - net worth $50,000,000 - be able to buy an £18,000 ticket to fly from America to Britain, in order to lecture me on that SqueezyJet flight to Italy I took two years ago? She would have to forego the beef carpaccio washed down with Laurent Perrier champagne that she enjoyed on the flight, before haranguing us about going veggie to save the planet.

This is from a left perspective but I reckon you'll like parts of it.

Climate hysteria
In April the streets of London were brought to a standstill in a protest in support of the demand to recognise an alleged ‘climate emergency’.

Didn't temps rise by 2 deg in 3 days after 9/11 when all flights in US airspace were band?
due to the vapor trails no being there to reflect the sun,

The link above will take you to news that wildfires are blazing out of control - across the Arctic (even Greenland). They've released the same amount of carbon dioxide during the hottest June since records began as Sweden does in a year. On the bright side, at least they might kill the dormant frozen deadly viruses.

That is very worrying. The vegetation in those areas will take a long time to grow back.

Doesn't all change at the same time.

Ancient global climate events rippled unevenly across the globe
By Sid Perkins Jul. 24, 2019 , 1:00 PM

In the past 2000 years, Earth has drifted in and out of extended periods of warmer- and cooler-than-normal climate, including the so-called Medieval Warm Period and the Little Ice Age. Scientists long thought that during these hot and cold spells, temperatures rose and fell in sync across the globe. In fact, Earth warmed and cooled unevenly, with different regions reaching peak high and low temperatures at different times, two new studies suggest. The one exception: Since the mid–19th century, warming trends have covered some 98% of the globe.

Widespread networks of weather stations that could accurately record local temperatures didn’t exist until the last half of the 1800s. But scientists can estimate past temperatures using a variety of natural proxies. These “paleothermometers” include the widths of tree rings and the proportions of isotopes—forms of atoms such as oxygen that contain different numbers of neutrons—in glacial ice, corals, clam shells, cave deposits, and even lake sediments.

Some interesting consequences of climate change.

More ancient monuments and historic ruins will be uncovered as extreme weather caused by climate change gets more frequent, an expert has said.

The remains of a shipwreck off the Abergele coast dating back 150 years was revealed by July's thunderstorms. It comes after a prehistoric forest and 200 archaeological sites were unearthed following extreme weather events.

Archaeologist Dr Paul Belford said "you'll see more and more of this" as the world warms up.

Experts have "tentatively identified" the recently-uncovered Abergele wreck as the 35-tonne wooden sloop Endeavour that sunk without trace in gales in October 1854.

Trump wasn't the first to suggest using nukes for climate modification.

AMERICA'S DECADES-OLD OBSESSION WITH NUKING HURRICANES (AND MORE)

... The truth, though, is that Donald Trump’s apparent brainstorm—as terrible an idea as it is—actually has a long history. Seventy years ago, it was at the forefront of American scientific thought. What makes Trump’s embrace of nuking hurricanes unique is that, broadly speaking, no policymaker has seriously considered it a good idea since the days that the 73-year-old president was wearing diapers. ...

In those heady early years of the atomic age, many scientists imagined a world where humans could routinely use nuclear weapons to cleave the earth and remake its climate. Decades before climate change became a major concern, one book, Almighty Atom: The Real Story of Atomic Energy, suggested using atomic weapons to melt the polar ice caps, gifting “the entire world a moister, warmer climate.” ..

Julian Huxley, brother of novelist Aldous Huxley and a renowned biologist who would become the founding director of the United Nations Educational, Scientific, and Cultural Organization, was particularly enthusiastic. He suggested at one point that nuclear weapons could be used to flood the Sahara, allowing the arid landscape to “blossom.” He argued in favor of “atomic dynamite” for “landscaping the earth.” ...

On the other side of the burgeoning Cold War, the Soviet Union was no less enthusiastic about the geo-engineering possibilities of nuclear power and atomic weapons. In fact, the Stalin-era Soviet government was particularly enthused with the idea of hurrying climate change along for the possibilities of opening its frigid Siberian east to thriving agriculture and bringing subtropical crops to the shores of the Black Sea. In a 1956 book called Soviet Electric Power, Arkadii Borisovich Markin suggested that, “Atom explosions will cut new canyons through mountain ranges and will speedily create canals, reservoirs, and seas [and] carry out huge excavation jobs.” The author brushed aside the obvious concerns, assuming that science would soon “find a method of protection against the radiation.” Soviet scientists proposed how to dam the Bering Strait and use massive nuclear-powered pumps to heat the Arctic Ocean. ...
