This data provides insights into the significant rise in atmospheric CO2 concentrations, highlighting the impact of human activities on Earth's climate. CO 2 Through the Seasons. A closer look at the carbon dioxide measurements at Mauna Loa …

This graph shows the change in global surface temperature compared to the long-term average from 1951 to 1980. Earth’s average surface temperature in 2024 was the warmest on record since recordkeeping began in 1880 (source: NASA/GISS).NASA’s analysis generally matches independent analyses prepared by the National Oceanic and Atmospheric Administration (NOAA) and other research groups.

This graph shows the change in global surface temperature compared to the long-term average from 1951 to 1980. Earth’s average surface temperature in 2023 was the warmest on record since recordkeeping began in 1880 (source: NASA/GISS).NASA’s analysis generally matches independent analyses prepared by the National Oceanic and Atmospheric Administration (NOAA) and other research groups.

This time series shows global changes in the concentration and distribution of carbon dioxide since 2002 at an altitude range of 1.9 to 8 miles. The yellow-to-red regions indicate higher concentrations of CO2, while blue-to-green areas indicate lower concentrations, measured in parts per million.

2023年3月7日 · This map shows mean (average) net emissions and removals of carbon dioxide from 2015 to 2020 using estimates informed by NASA’s OCO-2 satellite measurements. Countries where more carbon dioxide was removed than emitted appear as green depressions, while countries with higher emissions are tan or red and appear to pop off the page.

Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers, and the expansion of seawater as it warms.

The first graph shows atmospheric carbon dioxide (CO 2) levels measured by NOAA at Mauna Loa Observatory, Hawaii, since 1958. Since the onset of industrial times in the 18 th century, human activities have raised atmospheric CO 2 by 50% – meaning the amount of CO 2 is now 150% of its value in 1750.

2013年5月9日 · This graph shows the monthly mean atmospheric carbon dioxide at Mauna Loa Observatory, Hawaii, measured since 1958. A single data point has been added for the concentration recorded on May 9. The black curve represents the seasonally corrected data.

Methane (CH 4) is a powerful greenhouse gas, and is the second-largest contributor to climate warming after carbon dioxide (CO 2). A molecule of methane traps more heat than a molecule of CO 2, but methane has a relatively short lifespan of 7 to 12 years in the atmosphere, while CO 2 can persist for hundreds of years or more.

This chart shows annual estimates for the first 2,000 meters of ocean depth. Each data point in the upper chart represents a five-year average. For example, the 2022 value represents the average change in ocean heat content (since 1955) for the years 2020 up to and including 2024.
