Write a brief report on global warming and climate change as the head of an NGO for presentation in a meeting of the NGOs.
HON'BLE CHAIRPERSON OF THE MEETING.
Dear friends.
The meeting of the NGOs on the issue of Global warming is an august occasion and I feel honoured to present the report of GRENPACE, the NGO which I head in this meeting. Our reort comprises the general things about Global warming as an issue and the particular suggestions to combat the alarm.
Global warming is the increases in the average temperature of the atmosphere and oceans.
Causes: Gases like carbon dioxide,methane,nitrous oxide,sulphur hexafluoride,ozone, CFCs and water vapour trap some of Sun's energy within our atmosphere and increases the temperature of Earth's surface. This effect is called the " green house effect ". Decreased albedo over Earths surface also causes a rise in temperature by absorption of more sunlight. Albedo is the surface reflectivity of Sun's radiation. Cirrently Earth's albedo is about 0.30, i.e.30% of sun's energy is radiated back into space.
.Effects:Due to global warming, most small glaciers in india have totally melted down while the big glaciers have decreased in size, which has affected the ability to irrigate crops and has reduced stream-flows needed to keep dams and reservations replenished.
Forest fires:
Rising global temperature may cause forest fires that release more stored carbon into the atmosphere than the carbon cycle can reabsorb and also reduces forest area on the planet.
Spread of disease:
Global warming is expected to extend the favourable zones for vectors conveying infectious diseases such as dengue fever and malaria.
Solutions for global warming:
● we should choose the least-polluting,most efficient vehicle that meets our needs; choose alternatives like walking, or public transport.
●We should turn off the lights when we leave a room. Keep our airconditioning and heating systems properly maintained by changing air filters and keeping air conditioner coils clean.
●we should choose renewable sources of energy.
●in addition to storing carbon,trees planted in and around urban areas and residences can provide the much needed shade in the summer and reduce energy bills.
Thank you all.
