GLOBAL WARMING

GLOBAL WARMINGHello!I am Dickson John

646509ObjectivesEducate people about what is Global warming and how it takes place.Educate people about the main causes of Global warming.Educate people about the measures that can be taken as an individual to reduce Global warming. What is Global Warming?Global Warming is a term for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.How does it take place?Global Warming takes place due to excess green house gasses accumulating in the atmosphere. Greenhouse gases (GHGs) trap heat in the atmosphere. This trapped heat keeps the earth warm in order for us to survive. The Earth gets energy from the sun in the form of sunlight. Some of the energy from the sun is absorbed by Earth and heats up. The Earth cools down by giving off a different form of energy called Infrared Radiation. This Infrared Radiation is again absorbed by the GHGs making the Earths surface warmer. Carbon dioxide, methane, nitrous oxides, ozone, and water vapor are the most common GHGs causing Global Warming. CAUSES OF GLOBAL WARMING

Carbon Dioxide (CO2) Emission CO2 is mainly produced from burning of fossil fuels like Coal to produce electricity.

Burning of gasoline for transportation.

Illegal Logging

Forest Fires

Slash-and-burn agriculatural technique that involves cutting and burning of plants and trees in forests to create fields to fertilize crops. DeforestationCH4is emitted into the earths atmosphere during the production, processing, storage, transmission, and distribution of natural gas and petroleum.

Livestock such as cattle, buffalo and sheep produce large amounts of methane as their normal digestive process (enteric fermentation).

Manure that is stored in anaerobic conditions produce methane.

Landfill sites.Methane (CH4) EmissionsGlobal warming is irreversible but not unstoppable!Though you might feel like your lifestyle is insignificant compared to things like oil extraction or vehicle emissions, the choices we make in our day-to-day life- how we get around, what we eat, how we live- play a major role in slowing climate change. The good news is that there are simple steps you can take to help do your part in the fight against global warming.Fighting Global Warming

What can an individual do?Replace all your light bulbs into fluorescent bulbs which consume minimal electricity. Turn off the lights when you dont need them!

Unplug your electronics completely instead of switching them off since most electronics still consume electricity when they are switched off.

Purchase electronics that has ENERGY STAR ratings, an international standard for energy-efficient consumer products, typically utilize a minimum of 20 % less energy.

Plant trees that will provide shade and soak up carbon from the atmosphere instead of ornamental trees.

CONTDWalking or cycling instead of driving can play a huge role in reducing the global CO2 emissions.

If driving cannot be avoided then purchase a fuel-efficient car or use public transport where possible.

Modify your diet to include less meat so that methane and carbon dioxide emissions from livestock can be reduced.

The most important contribution to prevent global warming is to educate people about global warming and its causes and effects. Teach people on how an individual can contribute their part to fight global warming.

Thanks for listening!
