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:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

The current Senate draft of the US budget bill not only ends subsidies for wind and solar, but imposes a new tax of 30% or 50% of value on them, including on home rooftop solar, with any meaningful foreign-made components. You can't do any of this anymore without foreign-made components because the GOP is also gutting support for US manufacturing. Doing this is going to make US decarbonization effectively impossible.

If you're an American, call your representative and senators and tell them to vote down the bill so long as this is in it.

President Trump’s efforts to freeze climate spending have sparked warnings of rippling consequences in years ahead. For many climate scientists, the consequences are already here.

Even in places, like Central Texas, with a long history of floods, human-caused warming is creating the conditions for more frequent and severe deluges.

The overall message here I think is: action is still necessary, but the reality is that we're too caught up in politics and economics and we missed our chance at mitigation. Now we need to look to how to cope with what's coming.

The convergence of natural and human-influenced factors is probably intensifying the heat wave in the Mediterranean, a region that saw consecutive years of record-breaking ocean warmth in 2023 and 2024.

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.
