No benefits from warming even for subnival vegetation in the central Himalayas

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.

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.

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Secondary SuccessionSecondary succession is the natural process through which ecosystems recover after a disturbance, such as a wildfire, flood, or human activity, that doesn’t completely destroy the soil. Unlike primary succession, which starts from bare rock, secondary succession begins in areas where life previously existed, and soil remains. Grasses, shrubs, and trees gradually return, and the ecosystem moves toward stability again. Comprehending secondary succession allows us to...

Abiotic and Biotic FactorsEvery ecosystem is a complex network where living (biotic) and non-living (abiotic) components interact closely to maintain balance. Biotic factors include all living organisms, such as plants, animals, fungi, and microorganisms, that rely on each other for food, shelter, and reproduction. Abiotic factors, such as sunlight, temperature, water, air, and soil, provide the physical conditions necessary for life to exist. These non-living elements influence how organisms...
