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 our family we have two e-bikes - one smaller one larger, also many normal bikes, no more car. They are especially useful to get up the steep hills to the side of our valley, and also to pull shopping or dog in a trailer - up to 50kilos ok. Both e-bikes fold so they can easily go on the train. Both e-bikes were bought directly from china online, as we are not rich.
The smaller one is slower but manageable by low-teen-kids too. The larger one will go about 80km, pedalling, with small hills.
We find e-bikes don't make us lazy, rather they encourage us to make more trips, and pedal faster - still get fit.
So the european law that enforces pedalling rather than cruising is good, however the low european limit on e-bike power is unfortunate, maybe designed by people in flat countries, you need more power for hills or heavy loads.
We'd like two more to enable family trips, but those are too rare to justify the cost, and also no e-bike can last a whole day - for that we'd need solar panels on a trailer - project for later ...
