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.

Long-term Population Trends for America’s Birds

~† Shorebirds indicator trend data has not been updated since 2019.~

  • 5 Years After the 3 Billion Birds Lost Research, America Is Still Losing Birds: A 2019 study published in the journal Science sounded the alarm—showing a net loss of 3 billion birds in North America in the past 50 years. The 2025 State of the Birds report shows those losses are continuing, with declines among several bird trend indicators. Notably duck populations—a bright spot in past State of the Birds reports, with strong increases since 1970—have trended downward in recent years.
  • Conservation Works: Examples spotlighted throughout this report—from coastal restoration and conservation ranching to forest renewal and seabird translocations—show how proactive, concerted efforts and strategic investments can recover bird populations. The science is solid on how to bring birds back. Private lands conservation programs, and voluntary conservation partnerships for working lands, hold some of the best opportunities for sparking immediate turnarounds for birds.
  • Bird-Friendly Policies Bring Added Benefits for People, and Have Broad Support: Policies to reverse bird declines carry added benefits such as healthier working lands, cleaner water, and resilient landscapes that can withstand fires, floods, and drought. Plus birds are broadly popular—about 100 million Americans are birdwatchers, including large shares of hunters and anglers. All that birding activity stimulates the economy, with $279 billion in total economic output generated by birder expenditures.

America should probably stop blanketing the skies via aircraft with millions of gallons of general pesticide (pyrethroids in most areas I believe) that affect pretty much all insects as part of their mosquito control efforts around communities.

Very nice infographic that I have shared with my circle.
As an aside, I suspect this was made with R and ggplot2; it's nice to see the tooling I'm familiar with make such nice graphs.
