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.

A new framework aimed at increasing the competitiveness of European industry is targeting lower energy costs and stronger purchase incentives for local and sustainable products, according to a leaked early draft of the measures.

[...]

EUROPE FOCUS “European preference criteria” are set to become a prominent factor in public and private procurement, according to the draft text, as well as new labelling for industrial products to more clearly delineate greener products from fossil-based ones.

The new measures could set out “minimum local content” requirements along with more robust sustainability criteria for public procurement, as well as exploring options for embedding similar “non-cost criteria” into product legislation.

CIRCULARITY, HYDROGEN The Commission could be set to limit the export of waste raw materials deemed critical for circular production, and is expected to ease restrictions on movement of raw materials across the region in the Circular Economy Act, expected next year.

Policymakers are also looking to clarify rules on low-carbon hydrogen production, and are set to launch a third call for projects through the Hydrogen Bank, the auction house set up to incentivise projects and investment, in the third quarter 2025.

CBAM REFORMS, DECARBONISATION TARGETS With a targeted package for the chemicals sector, which the draft text refers to as the “industry of industries”, expected towards the end of the year, the Commissions’ review of the proposed carbon border adjustment mechanism (CBAM) continues.

Intended to levy fees on the CO2 emissions of energy-intensive goods imports such as steel and fertilizers, the Commission is proposing to simplify the framework ahead of its roll-out next year, and reduce the administrative burden on businesses.

A proposed dam in China’s Medog county would be the world’s largest hydroelectric project, surpassing even China’s Three Gorges Dam, which is currently the largest dam in the world. The Yarlung Tsangpo, originating from the Tibetan Plateau, flows into India as the Brahmaputra River and continues into Bangladesh as the Jamuna. And not surprisingly, China’s ambition has alarmed downstream countries.

Reports suggest that this dam could significantly alter water flow patterns, affecting millions of people who depend on the river for agriculture, fisheries, and daily consumption.

...

India, which relies heavily on the Brahmaputra River, is likely to face serious hydrological challenges. The river provides water to Assam, Arunachal Pradesh, and other northeastern states, supporting nearly 130 million people and six million hectares of farmland. If China diverts or controls the river’s flow, India could experience unpredictable floods during monsoon seasons and severe droughts in dry months. A 2024 study published in the Journal of Indo-Pacific Affairs warned that China could manipulate water releases, potentially affecting India’s economic and strategic interests. Indian hydrologists have expressed concerns that sediment flow, crucial for agriculture, may be blocked by the dam, reducing soil fertility in the northeastern plains.

...

China’s unilateral decision to build the Medog dam, without consulting downstream nations, raises geopolitical tensions in South Asia. The lack of a water-sharing treaty between China, India, and Bangladesh further exacerbates the situation. While China has provided hydrological data to India since 2006 and to Bangladesh since 2008, experts argue that such data-sharing agreements are insufficient in preventing potential water conflicts. India has expressed concerns about China’s control over transboundary rivers, with policymakers advocating for stronger diplomatic and strategic countermeasures.

Climate change is commonly treated as a single, global problem that needs to be "solved." This mindset may have been appropriate in the past, but at 1.5°C above the preindustrial average, it's clear that we are not going to solve climate change. Everyone is going to live in a changed and changing climate for centuries to come. In this powerful keynote session, Spencer Glendon, founder of Probable Futures, will show how essential it is to make adaptation a priority and how doing so can lead to stronger institutions, healthier communities, better food, and even more effective decarbonization. Whether you are interested in housing, transportation, water, insurance, community organizing, fruit, or any other aspect of society, this session will give you frameworks, tools, and examples to help you see the world around you more clearly and make better decisions.

In that context, Ho is sympathetic to the reasons climate scientists may not want to mention climate change, and to focus on something like air pollution instead. “It’s a safe thing to mention because it has nothing to do with climate change,” he says. “Air pollution is not one of the key words.”

“There’s a lot of uncertainty, there’s a lot of fear,” Ho adds. “And it shouldn’t be this way. Studying environmental sciences is about studying our life support system.”

The change would effectively transfer financial responsibility from oil drillers, auto manufacturers and others and leave Americans to face greater direct costs as warming continues.

This is the exact opposite of perpetrator-pays that applies to any other crime.
