From NASA: Atmospheric carbon dioxide (CO2) levels are higher than at any time in the past 400,000 years. During ice ages, CO2 levels were ~200 ppm, and during the warmer interglacial periods, ~280 ppm. In 2013, CO2 levels surpassed 400 ppm for the 1st time in recorded history. This recent rise in CO2 shows a constant relationship with fossil-fuel burning, and can be well accounted for based on the premise that ~60% of fossil-fuel emissions stay in the air.
@cmskiera someone just shared with me a video that discussed how even if we get off of gasoline, we can't/won't get off of oil. not sure what that means, other than ev cars alone might not save us?
I don't know the answer to that (but I'll see what I can find) @peeppeepcircus
IMHO, there's an upper limit to how much CO2 Earth's atmosphere can hold before the planet is uninhabitable for humans, and whatever we do to slow down that process is in the best interest of humanity.
Alternative energy sources for all sectors (but primarily transportation and energy generation) is an urgent need.
We need climate triage immediately.
@cmskiera 💯 🙏
It is surreal and absurd that we are not already in climate triage.
