Scientists are naturally conservative with predictions. It's unfortunately the case that climate change is generally happening much faster than those conservative predictions. All the more reason for urgency from governments.

Global renewable energy generation surpasses coal for first time
Record solar expansion and steady wind growth driving world’s shift away from fossil fuels in 2025, report finds The world’s wind and solar farms have generated more electricity than coal plants for the first time this year, marking a turning point for the global power system, according to research. A report by the climate thinktank Ember found that in the first six months of 2025, renewable energy outpaced the world’s growing appetite for electricity, leading to a small decline in coal and gas use.

There’s a persistent myth that new solar farms don’t really help tackle climate change because panels are “made with coal” and “never pay back” their carbon debt. This is simply false. - UN: solar ~8x cleaner than gas, ~19x than coal per kWh - panels repay CO2 in 4 months; save 57x over life
