CHANGECLIMATE THEIR CAUSES,EFFECTS AND SOLUTIONS

2. What is Climate Change? Climate change is a long-term shift in the statistics of the
weather (including its averages). For example, a change in the usual timing of rains or
temperatures can affect when plants bloom and set fruit, when insects hatch or when
streams are their fullest

3. Major Causes of
Climate Change
Presented by: Bishwas Chhetri

4. Natural Causes
• the arctic tundra and wetlands release methane, a
greenhousegas
• Earth naturally has a cycle of climate change that occurs
every40, 000 years
• the sun’s solar energy output is changing and naturally
increases Earth’s average temperature by about 1ºC every
century
• Earth’s orbit and tilt alter in relation to the sun, which
changes solar energyoutput

5. • Increasing green house gas emissions from burning fossil fuels-oil,
coal, gas
• Pollution, smogfromfactories
• Large forests have been cut down (trees absorb CO2 and pollution,
deforestation createsabout 6billion tonsof CO2 per year)
• Increasing world population-more people requires more food,
energy, transportation, etc. Farms animals release methane from
theirwastes.
• More people also means more CO2 production from respiration and
less treesto make room for humanpopulation

10. Presented by: Bishwas Chhetri
• Plant a tree
.Or two or three or four. Or give money to a group that will. Trees absorb CO2
.Reduce your waste – Measure your waste/garbage for one week. Then
reduce it the following week. Continue. Remember, when your waste is
taken away it still remains on Spaceship Earth, just out of view.
.Get Into Gardening. Grow vegetables and herbs. Do at your own pace
and comfort.
