The Greenhouse Effect. Increasing Greenhouses Gases Are Warming the Planet. Scientists attribute the global warming trend observed since the mid-20 th century to the human expansion of the "greenhouse effect" 1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Life on Earth depends on energy coming from ...

Video: how different factors, both natural and industrial, contribute to global warming. Video: How global warming stacks up A super high-definition view of how carbon dioxide in the air moves around the world with the winds.

Climate change has caused increased heat, drought, and insect outbreaks. In turn, these changes have made wildfires more numerous and severe. The warming climate has also caused a decline in water supplies, reduced agricultural yields, and triggered heat-related health impacts in cities.

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.

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.

Vital Signs of the Planet: Global Climate Change and Global Warming. How do we know it’s happening? Here’s the evidence.

2024年1月30日 · Current news and data streams about global warming and climate change from NASA. Earth system science is the study of how scientific data stemming from various fields of research, such as the atmosphere, oceans, land ice and others, fit together to form the current picture of our changing climate.

2021年11月2日 · Climate change may affect the production of maize (corn) and wheat as early as 2030 under a high greenhouse gas emissions scenario, according to a new NASA study published in the journal, Nature Food. Maize crop yields are projected to decline 24%, while wheat could potentially see growth of about 17%.
