Change is happening OP, just not fast enough.
10 years ago only 10% of the electricity we used in this country was from renewables, now it is 43%. The government's aim is to decarbonise ALL our power by 2035.
There are global agreements to limit the temperature rise to 1.5 degrees, although at the moment we're heading for 2.5 degrees, because governments still aren't doing enough.
Electric cars are now outselling petrol & diesel cars in the UK.
New petrol & diesel cars will be banned from 2030.
Gas boilers are being banned from new homes from 2035.
Many people are reducing their meat consumption voluntarily.
Many businesses are also taking a lead, e.g. on reducing plastic packaging and buying only renewable energy.
And one of the good things - maybe - to come out of the Ukraine crisis is that governments are realising that relying on Russia for their gas supplies is a bad idea, and they should be developing more renewable energy, more quickly.
