2024年4月9日 · The global average carbon dioxide set a new record high in 2023: 419.3 parts per million. Atmospheric carbon dioxide is now 50 percent higher than it was before the Industrial Revolution.

Vital Signs of the Planet: Global Climate Change and Global Warming. Current news and data streams about global warming and climate change from NASA. Graphs and an animated time series showing atmospheric carbon dioxide levels from the last three glacial cycles to present day.

2021年2月25日 · Over the past few years, we’ve received a lot of questions about carbon dioxide — how it traps heat, how it can have such a big effect if it only makes up a tiny percentage of the atmosphere, and more.

2024年10月23日 · Five key greenhouse gases are carbon dioxide, nitrous oxide, methane, chlorofluorocarbons, and water vapor. While the Sun has played a role in past climate changes, the evidence shows the current warming cannot be explained by the Sun.

2021年8月9日 · The evidence is clear that carbon dioxide (CO 2) is the main driver of climate change, even as other greenhouse gases and air pollutants also affect the climate. “Stabilizing the climate will require strong, rapid, and sustained reductions in greenhouse gas emissions, and reaching net zero CO 2 emissions.

2024年10月21日 · Climate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term.

2025年1月12日 · Global warming - Carbon Dioxide, Climate Change, Greenhouse Gases: Of the greenhouse gases, carbon dioxide (CO2) is the most significant. Natural sources of atmospheric CO2 include outgassing from volcanoes, the combustion and natural decay of organic matter, and respiration by aerobic (oxygen-using) organisms.

2025年1月16日 · To find out more about the role of CO 2 in warming the atmosphere, visit the Climate Change Indicators page. Carbon Dioxide Trends. Carbon dioxide emissions in the United States decreased by 1.5% between 1990 and 2022, excluding LULUCF sinks.

2024年10月23日 · In 1938, Guy Callendar connected carbon dioxide increases in Earth’s atmosphere to global warming. In 1941, Milutin Milankovic linked ice ages to Earth’s orbital characteristics. Gilbert Plass formulated the Carbon Dioxide Theory of Climate Change in 1956. 3. IPCC Sixth Assessment Report, WG1, Chapter 2 Vostok ice core data; NOAA Mauna Loa ...

3 天之前 · Global climate change is one of the most threatening problems of the modern world. It is a fact, and the leading cause is the increasing level of carbon dioxide concentration. Most scientists deeply believe in the impact of climate change-related global warming and how carbon dioxide contributes to increasing global warming. However, some scientists do […]
