Global Warming- is the rise in the normal temperature of the earths atmosphere and oceans
Green house gases such as carbon dioxide, water vapour, methane and nitrous oxide trap the heat from the infra red radiations of the sun and heat up the earth’s atmosphere. This has caused a rise in mean temperature of the earth’s atmosphere, causing global warming. Even though burning of fossil fuels in thermal power plants is the main source of producing green house gases, air pollution caused due to soot and diesel exhaust from road vehicles and industries is a greater contributor to global warming.
Consequences of Global warming are:
* Weather Patterns changes- Warmer water in the oceans pumps more energy into tropical storms, making them stronger and potentially more destructive. Even with storms of the same intensity, future hurricanes will cause more damage as higher sea levels and flooding
* Health is affected- more frequent and severe heat waves will result in a greater number of heat-related deaths. * Wildlife is affected- Increasing global temperatures are expected to disrupt ecosystems, pushing to extinction those species that cannot adapt.
* Sea level rise- Rising global temperatures will speed the melting of the icecaps cause the sea level to rise with more water entering
The Kyoto Protocol is an amendment to the United Nations Framework Convention on Climate Change (UNFCCC), an international treaty intended to bring countries together to reduce global warming. The Kyoto agreement reduces Global warming by:
* Putting restricting orders on their biggest polluters
* manage transportation to slow or reduce emissions from automobiles
How alternative energy reduce Global Warming:
* Alternative sources such as solar energy can be used to reduce global warming because this source of energy doesn’t...
