Climate - truthful information about climate, related activism and politics.

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 article didn't start bad. But then the author didn't get the right conclusion.

Yes, the current climate data are devastating. Yes, there is also development in some (mostly rich) countries. But to put this into perspective: while the rate of GHG emmissions need to drop faster than they did 2020 during the pandemic, they are just stagnating in developed countries while rising in developing countries. Globally carbon emissions are still rising.

The reality is: the climate is changing faster than anticipated and the transition away from fossil fuels is nowhere near fast enough. We need to stop emitting GHG basically yesterday. Instead we bury the 1.5 °C target and hope for carbon sinks to help us get to net zero. Both natural sinks as also artificial sinks. Artificial sinks are still extremely expensive and ineffective while the remaining natural carbon sinks get destroyed and turn into carbon emitters.

What would need to happen is a massive effort through all society in every country. That would also mean for first world countries to not only forgive debts of poor countries, but also at least help financing poor countries transition.

The majority of people are just starting to take climate change seriously and the threat is still underestimated by most.

No, this is not the time for stubborn optimism. This is the time for worry. This is the time for anger. This is the time to reject pledges and promises by governments and demand actual action and legislative change. Being optimistic won't help us change.
