The study's findings of accelerated global warming and the potential breach of the Paris Agreement's 1.5°C limit before 2030 could increase pressure on governments and industries to accelerate decarbonization efforts. This may lead to increased investment in renewable energy and related technologies, while potentially negatively impacting fossil fuel companies due to stricter regulations and reduced demand.
A new study by the Potsdam Institute for Climate Impact Research (PIK) has found a statistically significant acceleration of global warming since 2015. The research, co-authored by Grant Foster and led by Stefan Rahmstorf, analyzed five global temperature datasets (United States===NASA, NOAA, HadCRUT, Berkeley Earth, ERA5) after filtering out natural influences like El Niño and volcanic eruptions. The study indicates that the warming rate has increased to approximately 0.35°C per decade, compared to 0.2°C per decade from 1970 to 2015, marking the highest rate since 1880. If this trend continues, the 1.5°C limit of the Paris Agreement will be exceeded before 2030. The findings underscore the urgency of reducing global CO2 emissions. The United States' withdrawal from the United Nations Framework Convention on Climate Change (UNFCCC) and the United States===United States Environmental Protection Agency's rescission of greenhouse gas regulations are noted as actions hindering climate efforts.
