Global Climate Change01:50

Global Climate Change

24.0K
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.

Responses to Heat and Cold Stress

13.2K
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.

Decreased Body Temperature01:29

Decreased Body Temperature

578
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...

Threats to Biodiversity

21.9K
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...

Requirements for Human Life01:26

Requirements for Human Life

7.3K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Area of Science:

  • Ecology
  • Climate Change Biology
  • Zoology

Background:

  • Polar regions experience significant climate change impacts.
  • Current vulnerability assessments inadequately address heat challenges for polar terrestrial ectotherms.
  • Existing conclusions rely on temperate region data, potentially misrepresenting polar species' sensitivity.

Purpose of the Study:

  • To re-evaluate the thermal vulnerability of polar terrestrial ectotherms.
  • To challenge assumptions based on temperate climate data.
  • To highlight the need for region-specific assessments.

Main Methods:

  • Review of existing literature on polar ectotherm thermal tolerance.
  • Analysis of physiological data from cold-adapted species.
  • Comparative assessment with temperate ectotherm responses.

Main Results:

  • Limited available data suggest polar ectotherms exhibit higher sensitivity to warming than anticipated.
  • Extrapolation from temperate regions may underestimate heat-related risks for Arctic and Antarctic species.
  • Observed sensitivities challenge the low concern currently indicated by vulnerability assessments.

Conclusions:

  • Polar terrestrial ectotherms may be at greater risk from climate warming than currently recognized.
  • Further research is crucial to accurately assess the impact of rising temperatures on these unique ecosystems.
  • Conservation strategies must account for the specific thermal sensitivities of polar fauna.
