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.

​​The Science Behind Sea Level Rise: How Past Emissions Will Shape Our Future

Union of Concerned Scientists

The future trajectories are based on different scenarios, such as versions of the future where the world comes together to take action and phase out fossil fuels, or versions where fossil fuel production continues throughout this century. What causes sea level rise to persist for centuries?

Drilling Into the Differences Between Offshore Oil Drilling and Offshore Wind

Ocean Conservancy

Consider the record-breaking warm ocean temperatures of the past year, which has caused the largest coral bleaching event on record , habitat loss and species migration. Many scientists thought these high ocean temperatures would be years away, but the realities of climate change are not a distant threat.

New Report on Liability Considerations for Marine Carbon Dioxide Removal in the U.S.

Law Columbia

The burning of fossil fuels and other human activities are continuing to cause rapid temperature rise. Scientists have identified a number of land- and ocean-based carbon dioxide removal (CDR) approaches. Marine CDR approaches appear to hold great potential for uptake and sequestration of carbon dioxide.

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. As the ocean warms, it expands. That adds water to the oceans, which raises their level.

A 100% Renewable Energy Future is Possible, and We Need It

Union of Concerned Scientists

I also find it fascinating to learn about bigger, more powerful wind turbines that better harness wind energy on land and in the ocean. The shift from fossil fuels in the 100% RES scenario reduces the amount of harmful air pollution from power plants much more than in our “No New Policy”/business-as-usual scenario.

Delays and Disagreements: The IPCC’s Struggle to Stay on Course

Union of Concerned Scientists

The main objectives included: Approving and adopting outlines for the three major working group reports and an additional methodology report on carbon dioxide removal (CDR). Fossil fuels, which are central to mitigation discussions but were largely avoided, reflecting ongoing political tensions.
