Global Climate Change

Global Climate Change

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.

What is Climate?

What is Climate?

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.

Threats to Biodiversity

Threats to Biodiversity

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...

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Desert Amplification in a Warming Climate.

¹Department of Atmospheric and Environmental Sciences, SUNY at Albany, Albany, NY 12222, USA.

Scientific Reports

|August 20, 2016

Summary

Driest regions like deserts experience amplified warming due to greenhouse gases (GHGs). This desert amplification is linked to increased downward longwave radiation and water vapor feedbacks in a warming climate.

Area of Science:

Climate Science
Ecology
Atmospheric Science

Background:

Global warming trends show significant regional variations.
Drier ecosystems may exhibit unique responses to climate change.

Purpose of the Study:

To analyze surface temperature anomalies across different ecoregions.
To investigate the phenomenon of desert amplification in a warming climate.

Main Methods:

Analysis of observed and projected surface temperature anomalies (1950-2099).
Comparison of temperature trends across large-scale ecoregions (50°S-50°N).
Correlation of warming patterns with greenhouse gas radiative forcing.

Main Results:

Strongest and most persistent warming observed in driest ecoregions (e.g., Sahara, Arabian Peninsula).

Desert amplification increases linearly with global mean greenhouse gases (GHGs) radiative forcing.

Amplification is driven by enhanced downward longwave radiation due to a warmer, moister atmosphere.

Conclusions:

Desert amplification is a fundamental pattern of global warming in low- and mid-latitude terrestrial ecosystems.
Warming rates are inversely dependent on ecosystem dryness, influenced by water vapor feedbacks.
Water vapor feedbacks in the upper troposphere and near the desert surface contribute to this amplification.
