New research shows plants absorb 31% more CO2 than previously estimated, raising the global GPP to 157 petagrams per year. Using carbonyl sulfide as a proxy for photosynthesis, this study highlights tropical rainforests’ critical role as carbon sinks and stresses the importance of accurate photosynthesis modeling for climate predictions.

WASHINGTON (AP) — In a blow to the fight against climate change, the Supreme Court on Thursday limited how the nation’s main anti-air pollution law can be used to reduce carbon dioxide emissions from power plants.

During a press conference with Polish President Andrzej Duda, President Trump announced that the U.S. is going to deploy 1,000 more troops to Poland. Even though the soldiers and hardware will be taken from the 52,000-strong U.S. contingent in neighboring Germany, U.S. military deployments and operations require a great deal of energy and leave a major carbon footprint. A new report from Brown University has estimated that since the invasion of Afghanistan in 2001, the U.S. military has emitted 1,212 million metric tons of greenhouse gases. In 2017 alone, CO2 emissions added up to 59 million tons - more than many industrialized nations including Sweden and Switzerland.
