This event predicts whether 2026 will be the warmest year on record based on global average surface temperature measurements. The Primary Designated Source (PDS) will be NASA’s Global Temperature Index (GISTEMP) annual data release for 2026.
Market Rules According to the US Environmental Information Centers of Oceanic and Atmospheric Administration (NOAA), November 2023 was the warmest month ever in the world since it began recording global temperature 144 years ago. This "milestone" is yet another alarm of the climate crisis arising from human activity, and raises questions about the measurements for the coming months.
The Paris Accord came into force on , as a global commitment to reduce climate change. Among other goals, it set targets for each country to reduce its Greenhouse Gas (GHG) emissions. Globally, the goal would be to reduce GHG emissions by 43% by the end of 2030, compared to the levels verified in 2005. If by the end of 2030, the global Greenhouse Gas annual emissions on any ...

Over that period, average global sea level has: Sea level is a global climate change indicator. Through continuous long-term measurements of global sea level, scientists can see the ocean’s role in climate and the effects of a changing climate on the ocean. Since 1993, global mean sea level has risen by about 4 inches (10 centimeters).
NASA and the Federal Emergency Management Agency (FEMA) have released a guide that provides resources for adapting to and mitigating impacts of climate change. The guide, Building Alliances for Climate Action, includes various perspectives, stories, insights, and resources about climate change to help individuals and organizations make informed decisions.
A large amount of physical evidence shows that carbon dioxide (CO2) is the single most important greenhouse gas in the atmosphere controlling Earth's temperature. This is because CO2, like ozone, N2O, CH4, and chlorofluorocarbons, does not condense and precipitate from the atmosphere at current climate temperatures, whereas water vapor can and does.
The leading cause of coral bleaching is rising ocean temperatures due to climate change. Although runoff and pollutants, sunlight, and low tides can impact coral, those impacts normally occur near the shoreline in shallow waters.
Clouds and aerosols are two of the most important, but least understood, aspects of climate change. How much do you know about them?
Earth has many processes that regulate carbon, atmospheric carbon dioxide and its role in the carbon cycle and climate. How much do you know?
