May 19, 2015 · Some of the chemicals that replaced ozone-harming CFCs are long-lived greenhouse gases. At NOAA's lab in Boulder, Colorado, chemist Steve Montzka leads the effort to monitor the concentration of CFC-substitutes and their potential impact on global warming.

Aug 30, 2023 · Any reduction in emissions is beneficial. Rising emissions from China and India could eventually overshadow total U.S. emissions, and could easily push global warming past the 1.5°C goal, and even past the 2°C goal. This looming possibility might make U.S. emission reductions seem pointless, but they are not.

NOAA and NIST collaboratively developed a new capability to measure and model U.S. emissions of greenhouse gases and hazardous air pollutants. The main goals are to support research and development of GHG emission reduction plans and strategies. Urban GHG Emissions Measurement and Monitoring System (Urban-GEMMS)

Dec 12, 2023 · According to the newest Global Carbon Budget report, global emissions continue to rise and must be significantly reduced to meet global climate targets and avoid severe and deleterious effects of climate change.

Oct 3, 2024 · SRM is not considered a substitute for climate mitigation efforts, which include decarbonization and GHG emission cuts. SRM research is being conducted as a response to growing concerns that the pace of CO 2 emissions reductions and CDR technology development is not sufficient to avoid severe impacts of climate change in the next decades.

e. A combination of strategies is needed to reduce greenhouse gas emissions. The most immediate strategy is conservation of oil, gas, and coal, which we rely on as fuels for most of our transportation, heating, cooling, agriculture, and electricity.

Oct 29, 2020 · Stabilizing global temperature near its current level requires eliminating all emissions of heat-trapping gases or, equivalently, achieving a carbon-neutral society in which people remove as much carbon from the atmosphere as they emit.

Apr 9, 2024 · Based on the annual report from NOAA’s Global Monitoring Lab, global average atmospheric carbon dioxide was 419.3 parts per million (“ppm” for short) in 2023, setting a new record high.

NASA, NOAA, the National Institute of Standards and Technology (NIST), and the Environmental Protection Agency (EPA) teamed up to develop the U.S. Greenhouse Gas Center – a new web portal designed to make it easier to find data, information, and computer models from multiple agencies in one location.

Aug 22, 2023 · Highlights. Global average sea level has risen 8–9 inches (21–24 centimeters) since 1880. In 2023, global average sea level set a new record high—101.4 mm (3.99 inches) above 1993 levels.
