The document discusses changes in rainfall patterns due to climate change. It notes that greenhouse gas emissions are causing temperatures to rise, altering weather patterns and resulting in more extreme rainfall events - either floods or droughts. This poses risks to populations and can damage crops, villages, and ecosystems. While excess water in some areas could help drought-stricken regions, implications include issues like drought-induced migration, food shortages, mass migration due to flooding, and stronger typhoons causing more damage. Solutions proposed are water storage systems and extending tributaries.

1. Changing patterns of rainfall
by Alex, Manny, and Rene

2. Global Trend
● More extreme on both ends
● Either too much (flooding) or too little
(drought)
● Places with large populations have greater
risk of experiencing drought or flooding

3. Cause and Explanation
● Main cause are the increased greenhouse
gas emissions
● Increasing temperatures result to alterations
in weather patterns
● Melting ice caps, and rising sea levels

4. Consequences
Negatives:
● More flooding in certain areas
● Damages crops and villages etc.
● Ecosystems destroyed by excess water
● More drought in e.g. Sub-Saharan countries
Positives:
● Can use spare water to help areas with lack of water
● Increased rainfall might help certain areas suffering with
drought

5. Implications
Sahel drought (decreased farming)= massive migration
American Midwest drought= food and production shortage
Massive flooding (eg. Bangladesh)= displacement/mass migration
Change in temp results to stronger typhoons= greater damage costs
Ecological catastrophe= mass extinction

6. Solutions
● Water storage systems
● Extend tributaries
