2 days ago · Synopsis. An Inconvenient Truth presents in film form an illustrated talk on climate by Al Gore, aimed at alerting the public to an increasing "planetary emergency" due to global warming, and shows re-enacted incidents from his life story which influenced his concerns about environmental issues.
4 days ago · The greenhouse effect occurs when greenhouse gases in a planet's atmosphere insulate the planet from losing heat to space, raising its surface temperature. Surface heating can happen from an internal heat source as in the case of Jupiter, or from its host star as in the case of the Earth.
5 days ago · Global warming, the phenomenon of increasing average air temperatures near Earth’s surface over the past one to two centuries, happens mostly in the troposphere, the lowest level of the atmosphere, which extends from Earth’s surface up to a height of 6–11 miles.
2 days ago · In the case of Earth, the Sun emits shortwave radiation that passes through greenhouse gases to heat the Earth's surface. In response, the Earth's surface emits longwave radiation that is mostly absorbed by greenhouse gases.
3 days ago · The planet is in “critical condition,” scientists concluded after a planet health check revealed that six out of nine planetary boundaries have been breached. First published in 2009, the planetary boundaries framework defines and quantifies the limits within which human activities can safely operate without causing irreversible ...
4 days ago · The essence of Net Zero is to balance the amount of carbon dioxide, the primary greenhouse gas, emitted with the amount absorbed, stored, or offset through human activities. The main goal is to continuously reduce emissions to reach Carbon Neutrality and Net Zero Emissions, where the amount of greenhouse gases released by human activities is balanced by reductions and offsets in the Earth's ...
2 days ago · However, earlier systematic ULSM comparison projects assessed the energy balance but ignored the water balance, which is coupled to the energy balance. Here, we analyze the water balance representation in 19 ULSMs participating in the Urban-PLUMBER project using results for 20 sites spread across a range of climates and urban form characteristics.
