Hundreds of toxic sites in California threatened by sea level rise due to climate change

[Yo_Mama_Been_Loggin]

Hundreds of toxic sites in California will be threatened as sea levels rise due to climate change, according to environmental health professors at UC Berkeley and UCLA.

The professors released a new project Tuesday called "Toxic Tides" that highlights the impact rising sea levels will have on California in the next 100 years.

More than three feet of sea level rise will occur by 2100 if nothing is done about climate change, according to the project.

The rise in sea levels would threaten 400 hazardous facilities and 2,100 homes in California.

1. The last line jumped out at me...

“ The Union of Concerned Scientists in July said there are 876 hazardous waste sites under danger from flooding in the U.S. in the next 20 years”.

2. "More than three feet of sea level rise will occur by 2100..." - No it won't

The highest annual sea level rise anywhere in California is at San Diego with an increase of 2.2mm +/-0.15mm per year. In order to go up by 3 feet (914mm) by 2100, the annual increase would have to be 11.43mm per year starting this year and this would increase every year going forward that the SLR is below that level. There is zero evidence that sea level rise is accelerating along the California coast. Even if SLR increased to 3mm per year for the next 80 years, that's still less than 10 inches.

The two shared socioeconomic pathways (SSP1) that stay below 2°C (very low emissions and low emissions) require net zero emissions by mid- to late century and carbon removal. There are five scenarios:

very low emissions (SSP1-1.9),
low emissions (SSP1-2.6),
midlevel emissions (SSP2-4.5),
high emissions (SSP3-7.0), and
very high emissions (SSP5-8.5).

The very low emissions scenario meets the 1.5°C Paris Agreement goal with likely warming of 1.4°C by 2100—but it overshoots the target to just above 1.5°C midcentury before decreasing to 1.4°C.

The low emissions scenario reaches 1.8°C by 2100, just skirting under the high bounds of the Paris Agreement.

Midlevel emissions hit 2.7°C,

high emissions clock in at 3.6°C, and

very high emissions extend to 4.4°C in 2100.
