Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Extreme weather seems to make the headlines almost every week, as disasters increasingly strike out of season, break records, and hit places they never have before.

Decades of scientific research has proven that human-caused climate change is making some disasters more dangerous and more frequent. The burning of fossil fuels like oil, gas, and coal releases carbon dioxide into the Earth’s atmosphere, where it traps heat, warms the planet, and alters the conditions in which extreme weather forms. These changes are happening more rapidly than at any time in the last 800,000 years, according to climate records.

Below, we break down what experts know — and what they don’t — about the connections between climate change and flooding.

Not my favorite source, but not a lot of other coverage.

It's going to take two things to change this:

  • Communication to make sure that elected officials hear from us. That means calling, writing, turning up in person, trying to have private conversations with staff, etc.
  • Active intervention in primaries, so that it's much harder to get elected if you don't support decarbonization

Changing this view means showing them; that means calling, writing, turning up in person, talking in private to staff, etc.

The Labour government still refuses to marginalize those working to undermine climate policy using spin and misinformation.

The new Labour government in Britain has continued the Tory's authoritarian crackdown on dissent and watering down of climate targets to appease the fossil fuel lobbyists of Tufton Street, and welcomed the erstwhile enemies of democracy direct action to the administration.

At the same time, we have witnessed crumbling of the so-called fourth pillar of democracy - the press - and its failure to hold the government accountable for abandoning its campaign promises.

There is also a prequel.

If you hate the heat, you may have morbidly joked that you’ll have to move north to escape the impending wave of climate change. That’s true—but you may have to go further than you think.

In 2080, New York City will have a climate much like Lake Shore, Maryland. Seattle will look more like Portland, D.C. will be more akin to Paragould, Arkansas, and Austin’s closest analog isn’t even in the U.S. (it’ll be more like Nuevo Laredo, Mexico). These estimates are all courtesy of a new study in Nature Communications that finds modern analogs for what the climates of 540 North American cities will look like in about 60 years. On average, the closest analog for the 2080 climate for each city was about 528 miles away, and mostly to the south.

The fact that Boston will feel like Aberdeen, Maryland in 60 short years should drive the impact of global warming home for you. And that’s what Matt Fitzpatrick, an ecologist at the University of Maryland Center for Environmental Science and one of the two authors on the study, is hoping for. “I kept constantly hearing in the media about a 3°C increase in mean global temperature, or about the Paris Climate According keeping the change to 1.5°C. That just never resonated with me,” he says. In his normal scientific research, he uses modeling to figure out how climate change might impact where other species can live, so he wondered whether he could use similar techniques to note the shift’s impact on humans.

Most of the East Coast will start to look a lot more like the South, and many parts of the South will start to look like Mexico. You can see an overall trend with all 540 cities plotted, but let’s zoom in on the top 20 most populous cities in America. (Bonus: you can look at an interactive version of this map made by the researchers here, where you can search for your home town).

In a lot of cases, you can see just how big a difference the degree of emissions makes. Even if we manage to reign them in significantly, every city on here will have significant changes in their climate. And if we keep going at our current rate, well, we’re even worse off.

Some of these points go so far south they’re nearly off the map. And in fact, it’s worth noting that for a number of these cities, there weren’t even accurate analogs to point to.

In their study, Fitzpatrick and his co-author focused on the western hemisphere above the equator, but for many of the cities, there simply wasn’t a good comparison. They calculated mathematically how close each urban area was to its closest analog with a value called sigma—a sigma less than two indicates a pretty good match. Above two means it’s not great, but Fitzpatrick explains that they considered 12 different climate variables—sp that high sigma could simply mean the precipitation amounts weren’t a good match, for example.

A sigma over four, though, meant that there was truly no accurate analog above the equator. “Had we looked globally we may have found a closer analog in India or Africa,” Fitzpatrick says. “But once you do that, people aren’t gonna know what some town in India feels like.” If the point is to make climate change feel real, they had to stick within a relatively familiar area. But there are quite a lot of cities that won’t look like anything we know in the U.S. “What was surprising was how many of the cities, especially under [the higher emissions scenario], were off the charts, if you will, in terms of their non-analog-ness.”

With that many cities changing so drastically, Fitzpatrick notes that his grandchildren are unlikely to recognize the climate he lives in today. And hopefully his work can help people realize the impact of that change. “If you want to broadly lump people, there are those for whom there’s no amount of evidence or information that will change how they feel. And there are people on the other side that have seen enough, they understand the risks. But there’s also a lot of people in the middle that have heard a lot in the media, but it hasn’t really resonated with them,” Fitzpatrick explains. “My hope is that this helps those people have a ‘wow’ moment.”

There is a glaring lack of tracking for global recycling. Poor waste management is deeply connected to climate change, plastic pollution and global nutrient imbalances globally.

Economies also suffer from the lack of tracking. We extract, process and then landfill and incinerate trillions of dollars of materials per year. Instead, these could be recirculating, creating new jobs and reducing reliance on global trade.

To shift to alternative, circular models, we need better data on local and global waste management.

My research demonstrates that more local waste tracking through digitalization could yield multiple benefits. It could help track hyper-local recycling and reuse, initiatives that are usually considered too small and burdensome to include in national waste tracking efforts.

And compared to national waste tracking, localized waste tracking could also provide more timely and relevant insights on the effectiveness of policies, infrastructure investments and education.

Istanbul's Caferağa neighborhood has a longstanding reputation for its cultural richness and historic charm. Quaint cafes, restaurants and bars line the sidewalks. A thriving arts scene draws an eclectic crowd. More than 2.3 million visitors daily flock to the district in which Caferağa resides — but it's overwhelming the neighborhood's small community of 22,000 residents.

"The streets of Caferağa are struggling to bear the weight they carry," said Hanife Dağıstanlı, the neighborhood chief. "The sidewalks are too narrow and often blocked, and people are forced to step into the road just to keep moving." This overcrowding has made it hard for locals to navigate daily life, especially those who are older, have disabilities or are traveling with children or strollers. At the same time, heavy traffic contributes to Istanbul's worsening air pollution and discourages people from using cleaner travel options, like biking.
