Droughts and Wildfires
Higher temperatures brought on by climate change are expected to increase the amount of moisture that evaporates from land and water, which will also cause rainfall patterns to shift.
Drought May Lead to Hunger, Disease, Even War
Drought can have serious health, social, economic and political impacts with far-reaching consequences.
DROUGHT: A long period of below-average precipitation
ECOSYSTEM: A community of plants and animals and the physical environment in which they live.
Drought: An extended period with little or no precipitation; often affects crop production and availability of water supplies.

Drought. A period of abnormally dry weather long enough to cause serious shortages of water for agriculture and other needs in the affected area.
Drought: A naturally-occurring phenomenon that occurs when precipitation is significantly below normal levels, causing water levels to drop and vegetation to die.
Drought - An extended period of time with a reduced level of water, usually brought on by the absence of rainfall.
Drought: Although there is no universally accepted definition of drought, it is generally the term applied to periods of less than average precipitation over a certain period of time.

DROUGHT MECHANISMS
Drought is a meteorological event which can be defined as a period without rainfall of sufficient duration that plant growth is impacted negatively.
It is caused by prolonged drought, during which time the top layers of soil dry out and blow away.
the effects of drought stress/the effects of drought. The word is also often used confusingly in two senses, both to describe force and the condition induced in the organism by the force - a confusion of stimulus and response.
water stress effect The closing of the stomata by a plant in response to excessive water loss through transpiration or in response to drought conditions.
These eggs have a thick shell and are resistant to environmental extremes of drought, cold, and heat. They are capable of overwintering and are often produced during the fall and times of environmental stress.
The plant is a native of India and is very versatile, being able to withstand being submerged in water during floods and also having the ability to withstand the severe pressures of drought.

The effects include changes in rainfall patterns, sea level rise, potential droughts, habitat loss, and heat stress. The greenhouse gases of most concern are carbon dioxide, methane, and nitrous oxides.
