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.

In the 1980s and 1990s, climate change was a threat, not a reality. Back then, climate leaders hoped to slow or stop warming before our civilization would see material weather-related effects or reach levels of warming that would risk irreversible changes. Those leaders—people like George Woodwell, who created the institution that brought me into this work—achieved admirable results, building the infrastructure, frameworks, and culture that came to define the climate action community.

In 2026, what the climate leaders of the previous era hoped to prevent is now here. Global temperatures from the past three years (2023-2025) averaged more than 1.5°C above the pre-industrial level for the first time. Climate models project that we could reach 2°C of warming as early as the 2030s.

And yet, public acknowledgement and discussion of this physical reality remain confined to specialists. It has not penetrated mainstream climate messaging, media coverage, or public discourse anywhere near the scale its consequences demand. Some thought leaders even celebrate the current trajectory as a win compared to the much higher warming that once seemed likely.

The climate community is not a monolith, but having tracked climate messaging closely for over a decade, I believe the prevailing narratives are not keeping pace with the science. Terms like “doomerism” have discouraged realism, leading many to mistake clear-eyed risk assessment for defeatism or alarmism. The climate movement needs a shared narrative focused on what outcomes are inevitable, what we can still prevent, and what choices remain available. In other words: What futures can humanity still hope for?

there were apparently millions of americams that voted for a pedophile that stares at the sun during an eclipse and you're disappointed in public discourse on climate change? look no further than -only republican- policies in U.S. for last 30 years, plus the maliciousness of current administration and you have larger issues than the population as apparently they've been sufficiently manipulated.

Thanks foxnews.

It's a holographic simulation.. We will be fine.
