Our Planet's Fever: Understanding the Facts Behind the Heat

The Facts

• Temperature Increase: Over the past century, the average surface temperature has risen by about 2 degrees Fahrenheit.
• Consequences:
• Glaciers are melting.
• Sea levels are rising.
• Extreme weather events are becoming more frequent and intense.

Scientific Evidence

Scientists study various sources to understand the changes:

• Ice Cores
• Rocks
• Tree Rings

Findings:

• The planet is warming at a rate unprecedented in the past 10,000 years.
• Oceans are getting warmer.
• Ice sheets are shrinking.
• Snow cover is decreasing.
• Ocean acidification is increasing, harming marine life.

Extreme Weather Events

• Increase in Frequency and Intensity:
• Heat waves
• Droughts
• Heavy rains
• Tropical storms
• Hurricanes
• Typhoons
• Wildfires

Example: Wildfires are often triggered by drought and lightning storms.

Impacts on Human Health and Environment

• Sea Level Rise: In places like Georgia, sea levels are rising more rapidly due to land sinking.
• Intensified Storms: Tropical storms and hurricanes are becoming more intense.
• Health Issues: Extreme heat can cause:
• Heat stroke
• Dehydration
• Cardiovascular and nervous system problems

Notable Extreme Weather Events Linked to Climate Change

• Hurricane Dorian (2019)
• Cold Outbreak in the Eastern United States (2019)
• Record-Breaking Fires in California (2014)

Future Projections

• More land area will be affected by droughts.
• Droughts will be more intense.

The Human Factor

• Climate change affects everyone but hits vulnerable populations the hardest.
• Understanding the facts is the first step in addressing this global challenge.
