Broad Climate Change Concern in Florida Linked With Recent Extreme Weather
An increasing number of Floridians agree that human actions are causing climate change, including a record number of Florida Republicans. Virtually all respondents (90 percent) believe climate change is happening, with 65 percent attributing the causes to human actions, including 49 percent of GOP voters. Belief in and concern about human-caused climate change appears to be translating into support for policies to reduce emissions and reduce impacts. The explanation for this emerging consensus may be grounded in people’s lived experiences with weather events.
Research finds global emissions of several banned ozone-destroying chemicals are increasing
New analysis has found increasing emissions of several ozone-depleting chemicals despite their production being banned for most uses under the Montreal Protocol – and a loophole in the rules is likely responsible.
Wildfires in 2021 emitted a record-breaking amount of carbon dioxide
Carbon dioxide emissions from wildfires, which have been gradually increasing since 2000, spiked drastically to a record high in 2021, according to an international team of researchers led by Earth system scientists at the University of California, Irvine.
Johns Hopkins APL Releases First-Ever Global Estimates for Road Transportation Greenhouse Emissions Leveraging Artificial Intelligence and Satellite Images
APL scientists have leveraged the global coverage of satellite imagery and the strengths of machine learning to create the first automated approach for estimating greenhouse gas emissions from the road transportation sector.
Including all types of emissions shortens timeline to reach Paris Agreement temperature targets
Instead of focusing on carbon dioxide’s effect on future temperature, new research includes the related human-generated emissions of methane, nitrogen oxide and particle pollution. Expanding the scope increases the amount of future warming that is already guaranteed by past emissions, and shortens the timeline to reach the Paris Agreement temperature targets.
Target CO2 and non-carbon pollutants to slow climate change
Policies that focus solely on decarbonization will not be sufficient to keep the Earth’s temperature below the “tipping point” threshold scientists have long warned could result in a runaway greenhouse warming effect, according to research published May 23 in the Proceedings of the National Academy of Sciences.
Emissions tied to the international trade of agricultural goods are rising
Irvine, Calif., May 6, 2022 – Earth system scientists at the University of California, Irvine and other institutions have drawn the clearest line yet connecting consumers of agricultural produce in wealthier countries in Asia, Europe and North America with a growth in greenhouse gas emissions in less-developed nations, mostly in the Southern Hemisphere.
New Climate Pledges, if Fulfilled, Now Significantly More Likely to Prevent Worst of Global Warming
New climate pledges issued ahead of COP26 boost the chances of limiting global warming to 2 degrees, according to a new study in Science.
OU Engineers Move to Reduce Emissions and Improve Operating Efficiencies in Oil and Gas Industry
Whether for a natural gas pipeline or an offshore production platform, the carbon footprint of reciprocating engines in the oil and gas sector continues to get larger. Wanting to rein in these emissions, University of Oklahoma engineers have discovered that a 70% reduction in emissions from natural gas engines may be achievable.
Putting a price on climate change
A new study looks back on how ten years of scientific advancements have influenced emissions estimates, and explores how to resolve some of the most important outstanding gaps in existing models.
