So... we're at the point where it's more concise to state which heat records aren't being set daily?

Since SST is relatively stable (compared to more volatile things like air temperature) and is generally increasing, it's actually not unprecedented for it to be setting new daily record highs for an extended period of time. That happened during the 2016 el niño as well. It's just that this time it went on for longer than ever (I think) and was breaking previous records by an amount that's quite large for most of that time.

It's now no higher than it was last year, but it still has a long way to go before it reaches temperatures observed in years before that.

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.
