Global Warming

• This presentation illustrates how global warming
  and its effects of
• Climate pattern changes
• Health
• Warming water
• Ecosystem disruption, and how these areas effect
  the following categories
• Wildlife, vegetation, forests, human life,
  agriculture, and oceans

3
Climate Pattern Changes

• Consequence Warmer temperatures
• Average temperatures will rise as well as the
  frequency of heat waves.
• Since 1980, the earth has experienced 19 of its
  20 hottest years on record.
• Many places in North America had their hottest
  seasons or days on record in the late 1990s.

4
Climate Pattern Changes contin.

• Consequence Drought and wildfire
• Warmer water temperatures increase the
  probability of drought. Greater evaporation
  causes the increase of risk of wildfires.
• The 1999-2002 national drought was one of the 3
  most extensive droughts in the last 40 years.
• Dry conditions produces the worst wildfires in 50
  years in Florida in 1998.

5
Climate Pattern Changes contin.

• Consequence More intense rainstorms, floods.
• Warmer temperatures lead to more intense
  rainfall.
• The series of floods that has hit the U.S. since
  1993 racked up over 25 billion dollars in loses.
  
• National annual participation has increased
  between 5 and 10 percent since the early 20th
  century.

6
Health Effects

• Consequence Deadly heat waves and the spread of
  disease.
• More frequent and more intense heat waves could
  result in more hear-related deaths.
• In 2003 extreme heat waves caused more then
  20,000 deaths in Europe and more then 1,500
  deaths in India.
• Disease spreading mosquitoes are spreading as
  climate shifts.
• Thirty of the diseases that emerged in the last
  20 years may thrive in warmer and wetter weather.
  

7
Warming Water

• Consequence Melting glaciers, early ice thaw.
• Rising global temperature speeds up the melting
  of glaciers and ice caps.
• At the current rate all of the glaciers in
  Glacier National Park will be gone by 2070.

8
Warming Water contin.

• Consequence Sea level rise.
• Current rates of sea level rise are expected to
  increase, resulting in the loss of the coastal
  wetlands, and more.
• The current pace of sea level rise is 3 time the
  historical rate and is rising.

9
Ecosystem Disruption

• Consequence ecosystems shifts and species
  die-off.
• The increase in global temperatures is expected
  to disrupt ecosystems and result in the loss of
  species diversity.
• Over the past 25 years the penguin populations
  have shrunk by 33.
• In areas of California shoreline sea life is
  shifting northward probably in response to
  warming water.
• Global warming is likely to spur the
  disappearance of trout and salmon from as much as
  18-38 by 2090.
