NOAA’s Annual Greenhouse Gas Index, which tracks the warming influence of long-lived greenhouse gases, has increased by 41 percent from 1990 to 2017, up 1 percent from 2016 — with most of that attributable to rising carbon dioxide levels, according to NOAA climate scientists.The annual increase from 2019 to 2020 was higher than the increase from 2018 to 2019 and also higher than the mean growth rate over the past 10 years (0.99 ppb per year).Global emissions of carbon dioxide, a major greenhouse gas and driver of climate change, increased from 22.4 billion metric tons in 1990 to 35.8 billion in 2013, a rise of 60 percent.

Overall U.S. emissions in 2005, the most recent year examined, increased by less than 1 percent from the year before to the equivalent of 7,260 million metric tons of carbon dioxide. In 1990, emissions stood at 6,242 million tons.
How did greenhouse gas emissions change between 1990 and 2010?
Global carbon dioxide emissions increased by 45 percent between 1990 and 2010, reaching a record high 33 billion tons last year, according to a report by the European Commission’s Joint Research Center.
Are greenhouse gases increasing or decreasing?
In the United States, greenhouse gas emissions caused by human activities increased by 2 percent from 1990 to 2019. Since 2005, however, total U.S. greenhouse gas emissions have decreased by 12 percent. Carbon dioxide accounts for most of the nation’s emissions and most of the increase since 1990.
How much have greenhouse gases increased?
Global carbon emissions from fossil fuels have significantly increased since 1900. Since 1970, CO2 emissions have increased by about 90%, with emissions from fossil fuel combustion and industrial processes contributing about 78% of the total greenhouse gas emissions increase from 1970 to 2011.
Why did CO2 emissions go down in 1990?
The decrease in primary energy intensity was the largest contributing factor to lower CO2 emissions from fossil fuel combustion. Total energy consumption decreased while GDP increased, leading to an improvement in the emissions intensity of energy production and use.
