Global climate effects of summer Tibetan Plateau

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Cenozoic Plate TectonicsThe Earth's surface is always changing. The Cenozoic Era, which began about 66 million years ago and continues today, has been a time of major changes in Earth's land and oceans. Large pieces of Earth's crust, called tectonic plates, have moved to form mountains, shifting continents and opening new ocean basins. These movements have shaped the world as we know it.During the Cenozoic, the continents moved into their current positions. Mountain ranges like the Himalayas...

VenusVenus is the second planet from the Sun and is often called Earth's "sister planet" due to its similar size and composition. However, Venus's thick atmosphere, primarily composed of carbon dioxide, creates a runaway greenhouse effect, making it the hottest planet in the solar system. Strong winds and dense clouds of sulfuric acid make Venus an extreme and inhospitable place for humans. Studying Venus helps scientists better understand planetary atmospheres, climate change, and the role of...
