Our planet Earth is getting warmer… and… warmer… by almost 1 degree celsius now!

That is very BAD news! 

The heat is melting glaciers and sea ice, shifting precipitation patterns, and setting animals on the move.

Hurricanes and other storms are likely to become stronger.

Floods and droughts will become more common.

Less fresh water will be available. Some diseases will spread, such as mosquito-borne malaria.

Ecosystems will change: Some species will move farther north for better livelihood; others won’t be able to move and could become extinct.

With less ice on which to live and fish for food, polar bears have gotten considerably skinnier. If sea ice disappears one day, the polar bears will as well!

Earth’s Worst Enemy…

Carbon dioxide is the climate’s worst enemy. It’s released when oil, coal, and other fossil fuels are burned for energy—the energy we use to power our homes, cars, and smartphones.

The goal is simple. To effectively address global warming, we must significantly reduce the amount of heat-trapping emissions we are putting into the atmosphere.

The good news is that we have the technology and practical solutions at hand to accomplish it, for example, Science helps us transform our energy system to one that is cleaner and less dependent on coal and other fossil fuels.

Renewable Energy: Key to Fight Global Warming

Renewable energy produces no emissions and results in cleaner air and water for all. 

Wind Energy: Wind turbines that are typically 200 feet or more above ground are used to harness the wind and turn it into energy. When the wind blows, it turns the turbines blades. The blades are connected to a drive shaft that moves with the blades. The shaft is attached to a generator, which creates electricity.

Wind turbines do not release emissions that pollute the air and they do not require water for cooling.

Solar Energy: 

*Concentrated solar power uses mirrors to reflect and concentrate sunlight onto receivers that collect the solar energy and convert it to heat. This thermal energy can then be used to produce electricity via a steam turbine or heat engine driving a generator.

*Photovoltaic solar technology uses photovoltaic cells (PV) to convert sunlight directly into electricity. PV cells are made of semiconductors and can provide large amounts of power for the electric grid.

How Can Our Household Contribute to Curbing Global Warming 

Power our home with renewable energy.  

If we live in a house, we can install solar panels on the roof.  If we live in an apartment, we can choose a utility company that generates at least half its power from wind or solar.
