Crossing a climate tipping point doesn't mean tipping is inevitable - a threshold can be temporarily passed if overshoot is short-lived.

Limiting time over 1.5 °C would considerably reduce tipping point risks.

ESD Ideas: Climate tipping is not instantaneous – the duration of an overshoot matters
Abstract. Climate tipping points are not committed to occur automatically upon crossing critical thresholds in global warming, as is often assumed. Instead, it is possible to temporarily overshoot a t...

10% GDP boost to Global South from clean energy transition
A new Oxford Smith School report finds a rapid switch to renewables could double energy-sector productivity in low-to-middle income economies within 25 years. In many countries, this would result in a GDP boost by mid-century of around 10%.

"Infamy! Infamy! They've all got it in for me!" Keneth William's line from Carry on Cleo and one of my favourite one-liners. It's taken from Denis Norton's and Frank Muir's radio comedy show "Take It from Here".

Why on earth do the Tories want to keep people locked into high energy bills? And, come to that, why is the BBC citing Reform but saying nothing about climate science or renewable alternatives?
Complete madness - except for the fossil fuel industry of course
