But more than 40 researchers say they could bring "severe environmental damage" and urged countries to simply focus on reaching net zero, the only established way to limit global warming.

Experts say that global warming means that rains are increasingly being reported in higher reaches where it mostly snowed in the past, destabilising mountains further with water percolating and loosening the ground.

Transportation is the most significant source of climate-warming emissions in California and the U.S., and experts warn that the sector must become far cleaner to avoid the worst effects of global warming.

So despite a few days of cooler weather, Southern California can expect a slight warming trend to begin Friday into the weekend.

It predicted a decline of between 78% and 100% by the end of the century, depending on the level of global warming.
