Humans have caused 1.5 °C of long-term global warming according to new estimates

Warming is one aspect of climate change, but we'll likely see cascading effects in the system.

For example, as global temperatures rise we are seeing that AMOC (Atlantic Meridional Overturning Circulation), and as a result the Gulf Stream, are "slowing down". [1]

This could result in EU cooling down.

The clathrate gun hypothesis suggests that large releases of methane could cause abrupt climate shifts due to methane’s strong greenhouse effect. [2]

Its likely developing nations and their citizens will increase CO2 usage as they move towards a more western lifestyle.

That means there will be an increasing amount of energy production and usage.

Ideally we generate more with solar and nuclear.

Decreasing energy production and consumption is not a real solution.

Why not?

A 5 passenger vehicle can be 1200kg or 3000kg but both offer almost the same utility. A diet of mostly-plants can be just as delicious as one with a lot of beef. Building a house closer to work can be just as useful as building one a long ways away (more, actually).

Let's be honest here, a lot of these 5 passenger vehicles carry only the driver 90% of the times. For that use specifically it can be replaced with a 30 kg e-bike or scooter.
