Global Warming cause/effects
What are the consequences of increasing temperatures here on earth?
- North America: Decreasing snowpack in the western mountains; 5-20 percent increase in yields of rain-fed agriculture in some regions; increased frequency, intensity and duration of heat waves in cities that currently experience them.
- Latin America: Gradual replacement of tropical forest by savannah in eastern Amazonia; risk of significant biodiversity loss through species extinction in many tropical areas; significant changes in water availability for human consumption, agriculture and energy generation.
- Europe: Increased risk of inland flash floods; more frequent coastal flooding and increased erosion from storms and sea level rise; glacial retreat in mountainous areas; reduced snow cover and winter tourism; extensive species losses; reductions of crop productivity in southern Europe.
- Africa: By 2020, between 75 and 250 million people are projected to be exposed to increased water stress; yields from rain-fed agriculture could be reduced by up to 50 percent in some regions by 2020; agricultural production, including access to food, may be severely compromised.
- Asia: Freshwater availability projected to decrease in Central, South, East and Southeast Asia by the 2050s; coastal areas will be at risk due to increased flooding; death rate from disease associated with floods and droughts expected to rise in some regions.
What could we as humans do to help prevent or alleviate these consequences?
The things humans can do is stop littering and burning fosil fuels because its making the earth heat up and all the ice burgs are melting. Driving a car, using electricity to light and heat your home, and throwing away garbage all lead to greenhouse gas emissions. You can reduce emissions through simple actions like changing a light bulb, powering down electronics, using less water, and recycling. This site provides more than 25 easy steps you can take at home, school, the office, and on the road to protect the climate, reduce air pollution, and save money. Take action today! Small steps add up, if we all do our part.
