The latest study released by the Union of Concerned Scientists (UCS) sheds light on the significant impact of emissions from major fossil fuel producers and cement manufacturers on global temperature and sea level rise. The research extends sea level projections into the future, revealing how past emissions from the fossil fuel industry will continue to affect the planet for centuries to come.
For decades, the largest fossil fuel and cement producers have been aware of the role their products play in climate change. Despite this knowledge, they have actively spread misinformation to the public and reaped profits while communities worldwide have faced escalating climate-related challenges. Previous attribution research by UCS has established links between heat-trapping emissions and various climate impacts, such as increased greenhouse gas concentrations, rising air temperatures, sea levels, ocean acidification, and wildfire occurrences.
The new study combines these findings to explore the consequences of phasing out fossil fuels at different points in history. It reveals that emissions from major carbon polluters have contributed significantly to current surface air temperature and global mean sea level rise. Moreover, the study projects that past emissions will continue to drive sea level rise for centuries.
By comparing scenarios where emissions from the largest producers are removed at various time points, the study paints a picture of what the world could have been if timely action had been taken. The research utilizes the Carbon Majors database to quantify emissions associated with coal, oil, gas, and cement production by key industry players since 1854. Climate modeling using the MAGICC model shows that earlier phase-out of fossil fuel emissions would have resulted in lower temperatures and sea levels today.
The study’s findings align with previous UCS research, validating the methodology and models used. By projecting future temperatures and sea levels under different emissions scenarios, the research underscores the urgent need to address the climate crisis. The study’s updated approach allows for a forward-looking assessment of sea level rise, incorporating various drivers of change to provide insights into future impacts.
The research serves as a call to action, highlighting the responsibility of the fossil fuel industry in driving climate change and the need for accountability. Communities affected by climate impacts are increasingly seeking legal recourse against companies that knowingly contributed to the crisis. Research that can attribute specific climate impacts to emissions from these companies can support such litigation efforts and drive global action towards phasing out fossil fuels.
It is clear that the time for action is now. The world must transition away from fossil fuels and hold those responsible for climate harm to account. Researchers, policymakers, and individuals alike must work together to address the challenges posed by climate change and secure a sustainable future for generations to come.
