AGW consequences September 26, 2019
Why climate change is also a public health problem
https://abcnews.go.com/Health/climate-change-public-health-problem/story?id=65821388Disease-carrying insects, and their habitats, spread
More heat- and cold-related deaths from extreme temperatures
Air pollution triggers battery of health problems
Mental health disorders and violence in the wake of hurricanes and floods
Also, for a personal view, first frost comes later. I used to be a miserable hay fever sufferer until I got a battery of shots.
A glacier in the Alps might collapse, thanks to global warming, officials say
https://www.stuff.co.nz/travel/news/116103246/a-glacier-in-the-alps-might-collapse-thanks-to-global-warming-officials-sayGlobal warming has put a glacier in the Italian Alps at risk of collapse, officials warned, leading to road closures, travel restrictions, and evacuations in the immediate vicinity.
Municipal officials issued the order after surveyors observed a significant increase in the sliding speed of the Planpincieux glacier, which rests on the Italian side of the Grand Jorasses peak. The mountain is one of several in the Mont Blanc massif, which runs through Italy, France and part of Switzerland.
This is something I did not think of. I know glaciers are a part of our world and losing them would be a loss, but I thought their areas were undeveloped.
From Antarctica to the Oceans, Climate Change Damage Is About to Get a Lot Worse, IPCC Warns
https://insideclimatenews.org/news/25092019/ipcc-cryosphere-ocean-report-climate-change-sea-level-rise-greenland-antarcticaAs the planet warms, diverse ecosystems—from mountain glaciers to the icy Arctic to the oceans—are already seeing dangerous effects from climate change. Future warming will threaten food supplies, force the migration of countless species and dramatically change the icy regions of the world. The changes are coming. How much is up to us, scientists warn in a new report released Wednesday by the United Nations.
The article focuses most on the oceans, but also mentions other consequences. Everybody loses something. For example, in arctic areas, you think warmer weather is good? You might till the permafrost thaws under your house and it shifts and is damaged.
No Plan B: Deciding Not To Have Children Because of Climate Change
https://www.delmarvapublicradio.net/post/no-plan-b-deciding-not-have-children-because-climate-changeUnder current projections, analysts are expecting severe environmental disruptions due to climate change by the time babies born today enter adulthood.
This forecast has some young people questioning whether to bring more children into such a world.
Some don’t want to bring children into the world who will ultimately feel the same fear they do. They also worry about the climate footprint of raising a child. And, they don’t want their children to have to live in a world struggling with flooding, fires and more frequent harsh storms.
How does raising a child affect one’s carbon footprint? What would this mean for populations already in decline? We assemble a panel to find out.
The long term number of children per couple should be the replacement level. Maybe NPG is good for a few generations, but ultimately it must be ZPG or we die out.
Alaska residents are watching climate change warm the Arctic before their very eyes
https://www.nbcnews.com/think/opinion/alaska-residents-are-watching-climate-change-warm-arctic-their-very-ncna1058416Walter Peter, a Gwich’in hunter from Fort Yukon, Alaska, stood in front of the audience under an outdoor octagon of raw logs and listed the changes he’d seen: unreliable river ice, unpredictable salmon runs, altered goose migrations, tick-infested moose, diseased caribou. He spoke in a quiet, respectful voice and was respected in return. He didn’t crack a smile until he noted “there’s nothing better than fat moose kidneys and blueberry pancakes.” But he shook his head at the thought of all that is being lost.
Every culture and subculture in the world will lose many things that they treasure if AGW is unabated.
Extreme sea level events ‘will hit once a year by 2050’
https://www.theguardian.com/environment/2019/sep/25/extreme-sea-level-events-will-hit-once-a-year-by-2050Extreme sea level events that used to occur once a century will strike every year on many coasts by 2050, no matter whether climate heating emissions are curbed or not, according to a landmark report by the world’s scientists.
The stark assessment of the climate crisis in the world’s oceans and ice caps concludes that many serious impacts are already inevitable, from more intense storms to melting permafrost and dwindling marine life.
But far worse impacts will hit without urgent action to cut fossil fuel emissions, including eventual sea level rise of more than 4 metres in the worst case, an outcome that would redraw the map of the world and harm billions of people.
I live about 1000ft/300m above sea level. But migrants from the East Coast might crowd my high ground. I will be 92 in 2050 and my uncle is already older than that, so I may make it.
What an ice-free Arctic really means, and why it matters so much
https://www.cbc.ca/news/technology/ice-free-arctic-1.5291966And then there's the weather around the world. The jet stream, a column of air that travels from west to east that drives weather across the northern hemisphere, relies on the temperature difference between the Arctic and the south. But when the temperature difference is not as pronounced, the jet stream begins to develop kinks. This can have widespread effects such as creating systems that prolong heat waves in southern Ontario and Quebec or even Europe, or slow hurricanes to a near standstill, as was seen with Dorian earlier this month.
So although most Canadians — and most of the world's population — live far from the Arctic, its rapid changes will have effects felt across the globe.
"I think we have an incredible capacity to adapt, but we're going to push our limits, and we're going to live in a world that is already difficult for very many," Crowley said. But, he added, bluntly, "Of course we can better prepare, and be better at giving ourselves a chance at being resilient, but we need to stop crapping in our own bed."
Superstorm Sandy may have been enabled by the record small arctic sea ice, one poster saud to me here, so this might already be beginning.
Canadian fishermen feel effects of climate change as world panel sounds alarm bell
https://www.cbc.ca/news/canada/nova-scotia/un-climate-change-report-nova-scotia-lobster-fishery-1.5296635Boris Worm, a professor of marine biology at Halifax's Dalhousie University, contributed science that was assessed in the new report.
Worm said if the world continues on the current path, there will be 17 per cent less marine life globally on average by the end of the century.
Ocean temperatures change very slowly (thermal inertia), so I imagine there might be more like 70 percent less land life?
Panthera: At least 500 jaguars lost their lives or habitat in Amazon fires
https://news.mongabay.com/2019/09/panthera-at-least-500-jaguars-lost-their-lives-or-habitat-in-amazon-fires/he fires in the Amazon forest in Brazil and Bolivia this year have burned key habitats of at least 500 adult, resident jaguars as of September 17, experts at Panthera, the global wild cat conservation organization, estimate. The numbers will continue to increase until the rains come, researchers say.
In Bolivia in particular, the fires have so far destroyed over 2 million hectares of forest in one of South America’s key “catscape”, a region that Panthera has identified as having the highest predicted density of cat species on the continent.
Panthera researchers also predict that many more jaguars will also likely starve or turn to killing livestock in neighboring ranches as a consequence of the fires, likely increasing conflict with the ranchers.
Wildfires are more likely in a warmer world. Which will release more CO2. Making the world still warmer...
‘IT’S JUST BAFFLING’: APPLE GROWERS FACE AN UNKNOWN THREAT THAT’S KILLING TREES
https://www.alleghenyfront.org/its-just-baffling-apple-growers-face-an-unknown-threat-thats-killing-trees/Peters doesn’t think this is caused by an insect or a disease that spreads from tree to tree.
A study by Cornell University published this year found that weather-related stress like drought and severe cold could be an underlying cause.
Peters doesn’t believe that’s the whole story. She has other theories, including increased rainfall or certain herbicides. A variety of stressors could be working together to lead to Rapid Apple Decline.
“We just don’t know,” Peters said.
If AGW is part of it it is likely to get worse. I eat an apple a day(macintosh in the morning), so this is something I would not like.
Mountain Regions, ‘Taking the Heat,’ Face Growing Hazards As Ice Melts, UN Climate Panel Warns
https://www.circleofblue.org/2019/world/mountain-regions-taking-the-heat-face-growing-hazards-as-ice-melts-un-climate-panel-warns/Melting glacial ice, driven by man-made temperature changes, is disrupting the supply of water, food, and energy downstream while raising the risk of landslides, floods, and other natural hazards in the Alps, Andes, Caucasus, Himalayas, and other major mountain ranges. Along with the collapse of ice sheets on Antarctica and Greenland, the meltwaters also contribute to an accelerating rise in sea levels. In the Arctic, permafrost is weakening, causing land to slump and destabilizing roads and structures.
My cousin Sharon and her husband Bill live in Colorado. Bill is a ski instructor. At least he is now, if there is no skiing in a few years...
