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. ...

There's so much climate modification going on as it is that I don't think anyone as a real clue
as to whats really going on.

Global Warming or Bad Data? Garbage in...

Climate science has always suffered from the problem of shaky and missing data. Modern recording weather stations date only to the early 20th century.

And many of those stations have a big problem. While they haven’t changed appreciably over the years, the land around them has changed, often profoundly, with the great growth in urban and suburban areas. The weather station that was put, say, in the middle of a Nassau County, Long Island, potato field in 1923 is still in the same spot. But the potatoes are long gone, and now it’s behind a strip mall, twenty feet from the kitchen exhaust fan of a Chinese take-out joint.

A study by meteorologist Anthony Watts found that almost 90 percent of the 1221 weather stations in the U.S. did not meet the National Weather Service’s setting standards, which requires that they be at least 100 feet from any artificial heat source or radiating surface. You can see some of the most egregious violators here. To deal with this defective information, climate scientists, have “adjusted” the data to solve this problem. Invariably, these adjustments have made earlier data show lower temperatures, and recent data show higher ones.

To develop reliable data, the National Oceanic and Atmospheric Administration (NOAA) placed 114 state-of-the-art weather stations relatively evenly spaced about the lower 48 states. They were carefully sited to be away from urban areas, which are heat islands, airports, which can be affected by jet exhaust, etc.

The system became operative in 2005. Now, realclearenergy.com is reporting that there has been no increase in average temperatures in the continental United States over the last 14 years, as measured by these new stations. If anything, overall temperatures are slightly cooler than they were.

The effects on an Andean peak that was sketched by Humboldt.

... In the end, Humboldt spun his defeat on Chimborazo into a triumph that cemented his reputation as the era's superstar scientist and explorer—and his legacy. Not long after his descent from the mountain, he sketched a spectacular diagram that used the slopes of Chimborazo to depict a concept that had crystallized during his climb: that climate is an organizing principle of life, shaping the distinct communities of plants and animals found at different altitudes and latitudes. The diagram—Humboldt called it his Tableau Physique—has become what one recent paper described as "an iconic milestone, almost a foundation myth, in the history of ecology."

Today, the idea born on Chimborazo—that the physical environment shapes life's grand patterns—is giving scientists an intellectual framework for understanding a phenomenon Humboldt himself could not have anticipated: how human-driven climate change is transforming life.

Tropical mountains are ideal stages for watching climate change unfold. They compress many climates into a small space, as Humboldt wrote in his Essay on the Geography of Plants: "On this steep surface climbing from the ocean level to the perpetual snows, various climates follow one another and are superimposed, so to speak." Now, global warming is quickly reshuffling those montane climates. And few peaks record the impact of human-driven climate change more vividly than Chimborazo itself. The massive volcano, which last erupted 1500 years ago, rises just 1° south of the equator. On the peak's eastern slopes, moisture from the Amazon Basin next door—plus temperatures that rarely drop below freezing except at the highest elevations—nurture grassland, bogs, and springy cushions of moss and dwarf alpine plants, all highly sensitive to climate change. Below the summit sprawl 17 small glaciers, bellwethers of global warming and a crucial water source for tens of thousands of people living at lower elevations. ...

We could stop supporting their economies, but I suspect its mostly internal trade.

Or encourage them to change, but thats too tidy.

Anyway, we are too much in love with cheap tat

Here is an environmental messenger for you.

Old timers remember him, including our Queen, and interestingly David and Richard Attenborough.

(His writing is well worth reading, but he is not exactly a reliable narrator, and as I said once, he is a Wendigo).

Climate change brings mosquitoes and Dengue.

KATHMANDU, Nepal — When mosquito season brought past dengue outbreaks to regions across the Asian tropics, Nepal hardly had to worry. The high-altitude Himalayan country was typically too chilly for the disease-carrying insects to live. But with climate change opening new paths for the viral disease, Nepal is now reeling from an unprecedented outbreak.

At least 9,000 people — from 65 of Nepal’s 77 districts — have been diagnosed with dengue since August, including six patients who have died, according to government health data.

“We have never had an outbreak like this before,” says Dr. Basu Dev Pandey, director of the Sukraraj Tropical and Infectious Diseases Hospital in the nation’s capital, Kathmandu. With dozens of people lined up for blood testing on September 26 at the nearby fever clinic, set up this year to handle the outbreak, Pandey continues: “People are afraid.”

Is India one of the worst polluters per capita though?
That's irrelevant.
It's down to national governments to determine policies and decide whether to build more high-polluting power stations or go down a more eco-friendly route.
It's therefore vastly more important for governments representing populations of billions to be "greener" than more sparsely populated states.
