Why Were 2023 and 2024 So Hot?

Union of Concerned Scientists

Scientists are sounding the alarm because this warming is shockingly bigbigger than what we would have expected given the long-term warming trend from fossil fuel-caused climate change. Meanwhile, sharply cutting our use of fossil fuels is the best way to limit carbon dioxide (CO 2 ) emissions, the primary driver of climate change.

COP28 Global Methane Pledge Efforts Still Not Enough

Union of Concerned Scientists

The pledge is a voluntary agreement to reduce global methane emissions by 30 percent below 2020 levels by 2030; however, methane levels keep going up and we are woefully off track for meeting this goal. Compared to carbon dioxide (CO2), methane doesn’t linger for long in the atmosphere after being emitted.

Don’t Believe the Lies: Five Facts to Consider as the UN’s COP27 Comes to a Close

Union of Concerned Scientists

Union of Concerned Scientists’ (UCS) research shows that top fossil fuel producers’ emissions are responsible for as much as half of global surface temperature increase. Updated analysis from 2020 shows that emissions traced to the 88 largest carbon producers contributed approximately 60 percent?of

COP27 Global Methane Pledge Efforts Are Not Enough

Union of Concerned Scientists

The pledge is a voluntary agreement to reduce global methane emissions by 30 percent below 2020 levels by 2030. It is 80 times stronger than carbon dioxide (CO2) at trapping heat on short timescales. Methane emissions come from two main sources : fossil fuels and agriculture—primarily animal-based agriculture.

Has Gasoline Use in California Peaked?

Union of Concerned Scientists

Switching from fossil fuels like gasoline to increasingly clean electricity sources is vital for hitting climate and air pollution goals. The dip in gasoline use in 2020 was due to the reduction in personal vehicle use during the initial phases of the coronavirus pandemic. pounds of carbon dioxide emissions per gallon.

Sea Level Rise is Already Threatening Communities

Union of Concerned Scientists

The primary cause of accelerating sea level rise is human activity As people burn fossil fuels and emit heat-trapping gases like carbon dioxide, our atmosphere and our oceans warm up. First, we don’t know how much more carbon dioxide, methane, and other heat-trapping gases humanity will emit in the coming decades.
