“President Biden has wasted no time in moving to repudiate his predecessor’s regressive climate policies. That’s good news. This map shows which areas could be at high risk unless greenhouse-gas emissions are cut drastically.
We’ve colored the map to identify the top risks across the globe, using a model by Four Twenty Seven, a company that analyzes climate risks. Accumulated emissions in the atmosphere are causing accelerating risks for a number of climate hazards.”
Incidentally, the first hyperlink introduced me to an organization called 427 in California. I went to their site to learn: “The name Four Twenty Seven is a reference to California’s previous 2020 emissions target, 427 million tonnes of carbon.” I found through google that CA did meet its emissions targets for 2020.
President Biden has recommitted the United States to the Paris Agreement, which is great except that it doesn’t really mean much, since that agreement’s commitments are voluntary. And it might not even matter whether signatories meet their commitments, since their pledges weren’t rigorous enough to keep global warming “well below” two degrees Celsius, or 3.6 degrees Fahrenheit above preindustrial levels to begin with. According to Climate Action Tracker, a collaborative analysis from independent science nonprofits, only Morocco and Gambia have made commitments compatible with the goal of limiting warming to 1.5 degrees Celsius above preindustrial levels, and the commitments made by several major emitters, including China, Russia, Japan and the United States, are “highly insufficient” or “critically insufficient.” “

“I have a pastime, one that used to give me considerable pleasure, but lately it has morphed into a source of anxiety, even horror: earth-watching.
Let me explain.
The earth from space is an incomparably lovely sight. I mean the whole planet, pole to pole, waxing and waning and rotating in that time-generating way it has, and not the views from the International Space Station, which is in a low orbit about 200 miles up and gives us only part of the whole.
My earth-watching, made possible by NOAA and Colorado State University websites, originates in three geostationary weather satellites parked in exceedingly high orbits above the Equator. Despite their seemingly static positions, GOES-16 and 17, two American satellites, and Himawari-8, a Japanese one, are actually whizzing through space at 6,876 miles per hour. They do so to remain suspended imperturbably over the Ecuadorean-Colombian border, the Eastern Pacific and the Western Pacific respectively. At 22,236 miles above sea level, they are in effect falling around earth at the exact pace it turns.
“. . . . In 2018, extreme weather events such as severe drought in Afghanistan, Tropical Cyclone Gita in Samoa, and flooding in the Philippines, resulted in acute humanitarian needs. According to the Internal Displacement Monitoring Centre, there were 18.8 million new disaster-related internal displacements recorded in 2017. Most disaster displacement linked to natural hazards and the impacts of climate change is internal, with those affected remaining within their national borders. However, displacement across borders also occurs, and may be interrelated with situations of conflict or violence.
In all cases, people displaced by disasters have needs and vulnerabilities that must be addressed. People already displaced for reasons other than disasters linked to natural hazards – including refugees, stateless people, and the internally displaced – often reside in climate change ‘hotspots’ and may be exposed to secondary displacement. Moreover, similar impacts on their home areas can inhibit their ability to safely return.” . . . .
“If you’re a supporter of that radical extremist group Keep America Habitable for Human Beings, you might have been encouraged by the 2020 presidential race.
In 2016, climate change — the scientific fact of the earth’s encroaching uninhabitability — was mostly ignored, including in the debates between Donald Trump and Hillary Clinton. This year, the changing climate and what to do about it got airtime in both presidential debates and the vice-presidential debate. Climate change was also one of the top issues during the Democratic primary race. Several candidates published detailed climate plans; Joe Biden’s proposal is the most ambitious response to climate change ever proposed by a major-party nominee for president.
And yet I keep getting discouraged by how far there is to go. Voters, the candidates and especially the political media have not given it enough attention this year, considering the stakes at hand. Worse, when politicians do address climate change, the discussion in mainstream media is often uninformed, following a script favorable to oil companies.
These problems were on stark display in the ridiculous dust-up over Biden’s statement during the debate last week that the United States needs to transition away from oil. When asked about climate change, Biden told a series of truths. He noted, correctly, that it’s an “existential threat to humanity,” that “we don’t have much time” to address it, that doing so could create hundreds of thousands of jobs and that it would involve eliminating our reliance on the cause of the problem, fossil fuels.”
“Two major reports released this month paint a grim portrait of the future for our planet’s wildlife. First, the Living Planet Report from the World Wildlife Fund (WWF), published last week, found that in half a century, human activity has decimated global wildlife populations by an average of 68 percent.
The study analyzed population sizes of 4,392 monitored species of mammals, fish, birds, reptiles, and amphibians from 1970 to 2016, reports Karin Brulliard for the Washington Post. It found that populations in Latin America and the Caribbean fared the worst, with a staggering 94 percent decline in population. All told, the drastic species decline tracked in this study “signal a fundamentally broken relationship between humans and the natural world,” the WWF notes in a release.
“Wildfires are devastating the American West, but the United States isn’t the only place on Earth that’s burning. This year, other countries have also experienced their worst wildfires in decades, if not all of recorded history.
In each case, the contributing factors are different, but an underlying theme runs through the story: Hotter, drier seasons, driven by the burning of fossil fuels, have made the world more prone to erupt in flames.
“We don’t have a fire problem; we have many fire problems,” said Stephen J. Pyne, an emeritus professor at Arizona State University who studies wildfires and their history. “One, obviously, is a deep one. It has to do with fossil fuels and climate.” “
“The effects of global warming in the Arctic are so severe that the region is shifting to a different climate, one characterized less by ice and snow and more by open water and rain, scientists said Monday.
Already, they said, sea ice in the Arctic has declined so much that even an extremely cold year would not result in as much ice as was typical decades ago. Two other characteristics of the region’s climate, seasonal air temperatures and the number of days of rain instead of snow, are shifting in the same way, the researchers said.
The Arctic is among the parts of the world most influenced by climate change, with sharply rising temperatures, thawing permafrost and other effects in addition to shrinking sea ice. The study, by Lara Landrum and Marika M. Holland of the National Center for Atmospheric Research in Boulder, Colo., is an effort to put what is occurring in the region in context.
“Everybody knows the Arctic is changing,” said Dr. Landrum, a climate scientist and the lead author of the study, published in the journal Nature Climate Change. “We really wanted to quantify if is this a new climate.”
In other words, she said, “has the Arctic changed so much and so fast that the new climate cannot be predicted from the recent past?”
Using years of observational data from the region and computer models, the researchers found that sea ice is already in a new climate, in effect: The extent of ice in recent years is consistently less than what would be expected in even the worst year for ice in the mid-20th century.
Arctic sea ice has declined by about 12 percent per decade since satellite measurements began in the late 1970s, and the 13 lowest sea-ice years have all occurred since 2007. This year is expected to be a record or near-record low for ice extent, which will be determined by the end of this month as the summer melt period ends.”
“Torrential rains have submerged at least a quarter of Bangladesh, washing away the few things that count as assets for some of the world’s poorest people — their goats and chickens, houses of mud and tin, sacks of rice stored for the lean season.
It is the latest calamity to strike the delta nation of 165 million people. Only two months ago, a cyclone pummeled the country’s southwest. Along the coast, a rising sea has swallowed entire villages. And while it’s too soon to ascertain what role climate change has played in these latest floods, Bangladesh is already witnessing a pattern of more severe and more frequent river flooding than in the past along the mighty Brahmaputra River, scientists say, and that is projected to worsen in the years ahead as climate change intensifies the rains.
“The suffering will go up,” said Sajedul Hasan, the humanitarian director of BRAC, an international development organization based in Bangladesh that is distributing food, cash and liquid soap to displaced people.”
“This is one of the most striking inequities of the modern era. Those who are least responsible for polluting Earth’s atmosphere are among those most hurt by its consequences. The average American is responsible for 33 times more planet-warming carbon dioxide than the average Bangladeshi.
This chasm has bedeviled diplomacy for a generation, and it is once again in stark relief as the coronavirus pandemic upends the global economy and threatens to push the world’s most vulnerable people deeper into ruin.
An estimated 24 to 37 percent of the country’s landmass is submerged, according to government estimates and satellite data By Tuesday, according to the most recent figures available, nearly a million homes were inundated and 4.7 million people were affected. At least 54 have died, most of them children.
The current floods, which are a result of intense rains upstream on the Brahmaputra, could last through the middle of August. Until then, Taijul Islam, a 30-year-old sharecropper whose house has washed away, will have to camp out in a makeshift bamboo shelter on slightly higher ground. At least he was able to salvage the tin sheet that was once the roof of his house. Without it, he said, his extended family of nine would be exposed to the elements.
Mr. Islam’s predicament is multiplied by the millions among those on the front lines of climate change. Vanuatu is literally sinking into the Pacific. Pastoralists in the Horn of Africa are being pushed to the edge of survival by back-to-back droughts. In the megacity of Mumbai, the rains come in terrifying cloudbursts.”
Bravo. Here is one of many good comments:
Here we go again. The US with 5% of the worlds population uses 25% of its resources. The US is number one in co2 emissions per capita and is only exceeded by China, with 4x our population in total emissions. This, however, is not the whole story. In 1970 when Bangladesh became a country it had a population of ~65 million. It is now ~165 million. While they do not contribute individually or collectively anywhere near as much as a western person or country to climate change that kind of growth in one lifetime has disastrous effects on the local environment and how people live. More land is needed for food production, housing, clothing and on and on, and people spread out to previously uninhabited areas, (the environment always pays for human numbers and activity) increasing the damage when things like flooding happen. In the US a similar effect is found. In 1970 the US had ~205 million people with a per capita co2 emissions of ~23 tons each. In 2020 the US has ~330 million people with co2 emissions of ~16 tons each (a 25% reduction). Population growth has completely wiped out all the gains of reducing our per capita co2 emissions. The point of this? Without addressing population growth both in the west and in every other country, nothing will be achieved. The effect of humans on the environment is simple. Number of people x lifestyle = effects. Both sides of the equation have to be addressed everywhere to have any lasting effect.
“Did you know that the refrigerants contained in air-conditioners and refrigerators can be extremely harmful to the environment? Many refrigerants, such as chlorofluorocarbons (CFCs) damage the ozone layer, while others are extremely potent greenhouse gases.
In fact, one kilogram of the refrigerant R410a has the same greenhouse impact as two tonnes of carbon dioxide, which is the equivalent of running your car for six months.
That’s why Australia has specific laws that prohibit the importation of gases like CFCs and regulates the importation of synthetic greenhouse gases.
Refrigerants leak into the atmosphere from faulty or poorly maintained equipment, or when equipment is improperly disposed of.”
