TL;DR: This paper showed that the observed and anticipated impacts from human-caused climate change are bigger than previously thought, and showed that it is getting warmer in the United States and that the upward trend is clear.
Abstract: This year produced much new evidence that the observed and anticipated impacts from human-caused climate change are bigger than previously thought. The release of a new report by the United Nations’ Intergovernmental Panel on Climate Change made this point quite clearly by synthesizing tens of thousands of scientific papers. If you are still wondering whether it is indeed getting warmer, the answer is an unambiguous yes! Figure 1 displays the average measured daily temperature for the state of California, and the upward trend is clear.
TL;DR: In this article , the authors evaluated the pollutant concentration, emissions, and price impacts of RFG, RVP, California RFG and other boutique fuel rules and found that RFG continues to deliver large improvements in air quality, while the benefits from RVP and boutique fuels are either small or statistically insignificant.
Abstract: The Clean Air Act has authorized an array of fuel regulations to reduce the precursors to ambient ozone pollution, among other pollutants. With the emergence of stringent fuel regulations for the most pollution-intensive cities, and the opportunity for states to adopt fuel content regulations, the U.S. gasoline market has evolved over the past three decades to address local pollution. We have evaluated the pollutant concentration, emissions, and price impacts of Federal RFG, RVP, California RFG, and other boutique fuel rules. We find that California RFG continues to deliver large improvements in air quality, while the benefits from RFG, RVP and boutique fuels are either small or statistically insignificant. We note, that ex post impacts of reformulated fuels are smaller than those predicted by ex ante analyses.
