Air pollution is the introduction of airborne chemicals, particulate matter or biological materials that cause harm or discomfort to organisms. [59] The population growth , industrialization and motorization of human societies have significantly increased the amount of airborne pollutants in the Earth's atmosphere, causing noticeable problems ...
The qualities of arctic air are developed over ice and snow-covered ground. Arctic air is deeply cold, colder than polar air masses. Arctic air can be shallow in the summer, and rapidly modify as it moves equatorward. [8] Polar air masses develop over higher latitudes over the land or ocean, are very stable, and generally shallower than arctic air.

Rhine cutting through Flims rockslide debris. The Flims rockslide happened about 10,000 years ago (8000 BC) in eastern Switzerland. It is the largest known landslide in the Alps, [1] [2] and the biggest worldwide whose effects are still visible, moving some 12 km 3 (2.9 cu mi) of rock, about 300 times that of the historic Swiss Goldau landslide.
The claim: Climate change has only had 'positive effects' on global food production. An Oct. 20 Facebook post (direct link, archive link) includes a graph that shows global wheat, rice and coarse ...
The two models and the data that support them can be reconciled by large-scale recycling of the continental crust, particularly during the early stages of Earth's history. [55] New continental crust forms as a result of plate tectonics, a process ultimately driven by the continuous loss of heat from Earth's interior.
Arch Manning’s biggest fan is his dad, Cooper Manning. The Texas Longhorns quarterback comes from a football dynasty: Arch is the grandson of former New Orleans Saints quarterback Archie Manning ...
Projected global surface temperature changes relative to 1850–1900, based on CMIP6 multi-model mean changes. The IPCC Sixth Assessment Report defines global mean surface temperature (GMST) as the "estimated global average of near-surface air temperatures over land and sea ice, and sea surface temperature (SST) over ice-free ocean regions, with changes normally expressed as departures from a ...
