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 startup Gigablue announced with fanfare this year that it reached a historic milestone: selling 200,000 carbon credits to fund what it describes as a groundbreaking technology in the fight against climate change.

the company says it has designed particles that when released in the ocean will trap carbon at the bottom of the sea.

Gigablue expects the carbon to be trapped there for hundreds to thousands of years.

While Gigablue has made several commercial deals, it has not yet revealed what its particles are made of. (...) "It's proprietary,"

The success of the company's method, they said, will depend on how much algae grows on the particles, and the amount that sinks to the deep ocean. So far, Gigablue has not released any studies demonstrating those rates.

"What we've got is a situation of a company, a startup, upfront selling large quantities of credits for a technology that is unproven,"

Reminder for people living in hurricane-prone locations: forecasting will not be great moving forward. Get prepared now, and expect even less help from the govt (if any) if the worst happens

In recent years, China has been grappling with severe flood crises that have displaced millions, caused heavy economic losses, and exposed vulnerabilities in its infrastructure and disaster management systems. The China flood crisis is not just a national emergency—it is a reflection of global climate patterns that are becoming increasingly unpredictable and devastating. With torrential rains now an annual occurrence during the summer monsoon, especially in provinces like Henan, Sichuan, and Guangdong, the nation faces a daunting environmental challenge. This article explores the roots, repercussions, and remedies of China’s ongoing flood dilemma.

[...]

Floods in China are not new; the country has a long history of river-based civilizations, particularly along the Yangtze, Yellow, and Pearl Rivers. However, climate change has intensified the severity and frequency of floods, turning seasonal rains into life-threatening disasters.

[...]

At the start of July 2025, China's north and west is again on alert after sweeping rains trigger deadly floods.

China's north and west braced for more flash floods and landslides on Thursday as annual 'Plum Rains' left a trail of destruction and prompted the mobilisation of thousands of rescue workers to pull people from floodwaters.

Red alerts were issued tracing the rains as they moved from the southwestern province of Sichuan through the northwestern province of Gansu, and up to the northeastern province of Liaoning [...]

Extreme rainfall and severe flooding, which meteorologists link to climate change, increasingly pose major challenges for policymakers as they threaten to overwhelm ageing flood defences, displace millions and wreak havoc on China's $2.8 trillion agricultural sector.

Economic losses from natural disasters exceeded $10 billion last July, when the 'Plum Rains' - named for their timing coinciding with plums ripening along China's Yangtze River during the East Asia monsoon - typically reach their peak.

[...] According to Climate Analytics, a global climate science and policy institute engaged around the world in driving and supporting climate action, China not on track for a 1.5°C-aligned pathway to align with the Paris Agreement’s 1.5°C goal.

When the Trump administration began taking down federal resources on climate change, I started pre-emptively archiving reports and data sets in the event that they're no longer accessible. That proved to be a smart move, as the NCA5 website just went dark this week. That's a huge blow to the layperson, as that was one of the most comprehensive resources on climate change for our nation. Thankfully I had the data backed up on multiple hard drives and cloud servers, so we can continue to provide this information to those who need it.

So far I've archived the following resources (which are no longer available from their official websites):

The following resources are still live, but I've archived them pre-emptively for safety:

What other US government resources might be on the chopping block? I'm primarily looking for reports and data related to climate change, resilience, and adaptation, and ideally in a downloadable format (PDF, Excel, CSV, etc.).

ANCHORAGE, Alaska (AP) — For the first time ever, parts of Alaska will be under a heat advisory — but you can put an asterisk at the end of that term.

It’s not the first instance of unusually high temperatures in what many consider the nation’s coldest state, but the National Weather Service only recently allowed for heat advisories to be issued there. Information on similarly warm weather conditions previously came in the form of “special weather statements.”

Using the heat advisory label could help people better understand the weather’s severity and potential danger, something a nondescript “special weather statement” didn’t convey.

The first advisory is for Sunday in Fairbanks, where temperatures are expected to top 85 degrees Fahrenheit (29 degrees Celsius). Fairbanks has has been warmer in the past, but this is unusual for June, officials said.
