28 Φεβ 2024 · By default, the map overlays show projected conditions in a world warmed by 3 °C above the average temperature from 1850 to 1900. The controls at top left change the overview to a world warmed by 1 °C (reflecting average conditions over the past couple of decades), 1.5 °C, or 2 °C.
10 Σεπ 2019 · Global warming and land use practices, such as farming, could change the environment for microbes living in the soil and alter the amount of greenhouse gases they release into the atmosphere.
30 Ιαν 2024 · Go on a webquest to learn how NASA helps study and protect the land, air, water, and ice. Vital Signs of the Planet: Global Climate Change and Global Warming. Current news and data streams about global warming and climate change from NASA.
NASA provides the robust scientific data needed to understand climate change. more From space, sky, sea, and land, NASA provides detailed climate data and research to the world.
The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere. We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves.
According to an ongoing temperature analysis led by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by at least 1.1° Celsius (1.9° Fahrenheit) since 1880. The majority of the warming has occurred since 1975, at a rate of roughly 0.15 to 0.20°C per decade.
