The Arctic is heating

Update:

"the temperatures here [in the Arctic] are rising nearly four times faster than in the rest of the planet — and that’s just the thermometer’s reading. When it comes to geopolitics, the coldest region in the world risks becoming its hottest.

* * *

The region’s fast-growing militarization, fueled by increased international tensions, are compounding a push to benefit from the Arctic’s strategic and economic potential. Melting ice is also creating new shipping lanes and opening natural resources to exploitation, making strategic control of the Arctic ever more enticing."

Why don't we have more spending on climate action?

2018: A warning

The latest IPCC report had shown that "the Nationally Determined Contributions set voluntarily by signatories to the Paris accord are vastly insufficient. Even if they are met, the increase in average global temperature will surpass 3°C by 2100, and will continue to rise still further after that." So, José Antonio Ocampo wrote, "humanity cannot afford to act gradually on this issue. The Stern Review, the latest IPCC report, and the UNEP have all concluded that current efforts to reduce emissions must be stepped up substantially." That means that "the country that is historically responsible for the largest share of greenhouse-gas emissions – the United States – must return to the agreement and show leadership on this issue once again."

2019: What we almost had

Noah Smith (Bloomberg, 12 Feb. 2019) supports investing in infrastructure: "The original Green New Deal’s goal of building a smart electrical grid is a good one, as is the idea to retrofit American buildings to have net zero emissions." However:

The Green New Deal, proposed by Representative Alexandria Ocasio-Cortez, has two big flaws. First, the plan overreaches in its desire to deliver a raft of expensive new entitlements — guaranteed jobs, benefits, health care, housing, education, income and more. If the large deficits required to pay for all of these things ended up harming the economy, it would actually hurt the cause of limiting climate change rather than help it. Second, the plan focuses far too much on the U.S.’s own carbon emissions. The U.S. accounts for only about 14 percent of global carbon output, and that percent is falling every day. The climate change battle will be won or lost in developing countries such as China...

Smith would prefer to see the US emphasize the development of green technology, and scale it, to help give "developing countries a way to reduce carbon output without threatening their economic growth."

2020: Expensive

22 disasters, 262 dead, $95bn in damages: US saw record year for climate-driven catastrophes": Report shows US was battered by punishing extreme weather on both the east and west coasts in 2020. Oliver Milman, Guardian, 8 Jan 2021

2022: No such luck (the original Green New Deal)

In 2020, when governments began spending on COVID mitigation, "the opportunity flashed brightly for climate action," when "something like a Green New Deal seemed not just conceivable but potentially the basic model for public investment the world over." Indeed:

"a team led by Marina Andrijevic and Joeri Rogelj estimated that if the world could spend just 10 percent of the money it had spent up to that point on Covid relief over each of the following five years — half of total Covid relief spending, in other words — it would be enough to bring about a comprehensive green transition, meet the goals of the Paris accord and keep the planet well below two degrees Celsius of warming."

But that spending didn't happen.

"At least $14 trillion," the New York Times article says, was spent by the countries of the Group of 20 on pandemic relief of one kind or another, according to an analysis published in Nature in March. Just 6 percent of it was spent in ways that could reduce emissions." Proportionately, that's only half of what these countries spent on cutting emissions after the 2007–09 recession.

"Public and political support for action to tackle the biggest crisis facing humanity IS is ebbing, just when it’s most vital … "Until April 2024, every single poll showed more support for increasing spending on climate change than reducing it. Since then, every poll has shown the opposite"

It's the biggest economic issue though

From Davos, Switzerland in January 2024: The World Economic Forum's "2024 global risk report names extreme weather events, critical changes to Earth systems, and biodiversity loss and ecosystem collapse as the three biggest global risks we collectively face over the next ten years." — Katharine Hayhoe, LinkedIn

Climate chaos is already making us poorer. We're just pretending it's not. Playing make-believe is not a plan. It's time for real-world strategies. Alex Steffen, The Snap Forward, Sep 26, 2025

Oregon is set to lose an additional $400 million in federal grants awarded for climate action and is among more than a dozen Democratic states losing federal funding after the Trump administration terminated nearly $8 billion for those states this week.

See this article, "Trump ‘retired’ a database tracking the most expensive weather disasters. Now it’s back — and finding over $100B in losses," Andrew Freedman, CNN, Oct 22, 2025:

"The Billion-Dollar Weather and Climate Disasters Database, which the Trump administration “retired” in May, has relaunched outside of the government using the same methodology. In its first update at the new site, the database shows that the first six months of 2025 have been the most expensive first six months of any year since 1980."

Stratospheric Aerosol Injection (SAI): A way to lower global temperatures?

Stratospheric Aerosol Injection (SAI) is a "hypothetical 'band aid' fix for global warming," writes Dustin T. Cox. It would involve putting aerosols into the sky so that they reflect some sunlight back into space. Like the cloud emitted by a volcano, SAI could cause global dimming.

Atmospheric scientist Frank Keutsch has had a research project at Harvard University for several years. It's called the Stratospheric Controlled Perturbation Experiment (SCoPEx), and it inquires about the risks of SAI. A notable risk, according to Oxford geophysicist Raymond Pierrehumbert, is 'termination shock' — meaning that, in Cox's words, "once we started injecting the atmosphere with aerosols, we could never stop," as stopping would suddenly raise global temperatures catastrophically.

That, indeed, sounds like a risk.

What projects can help us reach climate goals?

Alicia Elliott writes:

"The most recent report claims that rich countries must end their oil and gas production entirely by 2034 — 12 short years away — in order to cap global warming at 1.5 degrees Celsius and give poorer countries time to replace fossil fuel income. Considering how reluctant our world is to give up fossil fuels — or, more directly, the money made by fossil fuels — it's hard to see this happening."

In a 2018 article, Casey Williams explained that "Climate change doesn’t describe a single future catastrophe, but a slow and uneven unraveling, a drawn-out apocalypse that began long ago and that will stretch to an end that probably won’t feel like much of an ending at all." It affects different people differently. "For the wealthy and well-connected, climate change will not feel catastrophic most of the time." Therefore, to address climate change may be to address "the everyday injustices that make the present unbearable for so many."

Faron Sage says,"Projects like Moral Imaginations and Thrutopia and activists like Rob Hopkins and Manda Scott are creating a wonderful ground swell of imaginative possibilities that are profoundly necessary to fire our collective inspiration."

Kathryn Schulz, writing in 2015 about earthquake anticipation or "ecological reckoning" in general, said: "apocalyptic visions are a form of escapism, not a moral summons, and still less a plan of action."

Climate legislation wins in the US

Hello to the five people who read my climate posts. If you're on Twitter, please follow Nick Abraham of the LCV – League of Conservation Voters.


In late July 2022, Sen. Joe Manchin, who had been stalling, finally got on board and said he'd vote for the Democratic Party's climate legislation. Climate activists are relieved, though the spending is insufficient to solve the entire problem and the bill makes concessions to keep the fossil fuel industry alive. Sen. Susan Collins complained that the Democrats moved too quickly and that, for some reason, a Republican loss on climate would prompt the Republicans to take their anger out on gay people. See: "Susan Collins: Democrats’ Climate Deal May Doom Bipartisan Efforts On Same-Sex Marriage" and "Veterans, Same-Sex Couples Stand To Lose In GOP Hissy Fit Over Democratic Deal" and "How secret negotiations revived Joe Biden's agenda and shocked Washington"
