Measures to check Global warming

•Climate: “Average Weather of an area or environmental factors of an area”

Includes:-Light, Temperature, Humadity, Wind, Gases, Water etc. which average for about 30 years.

“Changes in Environmental

condition of an area over long period of time”

These Change Effect the

Agriculture.

Migration of animals.

Hydrological cycle.

Wind pattern.

Distribution of rainfall etc.

Changes the temperature by moe than 2°C is disastrous for various ecosystem on the earth including man, some

area will become inhabitable of drought or flood following a rise a average sea level

i. Climate Change

ii. Effect On sea Levels

iii. Reduction Of biodiversity

iv. Effect on Agriculture

v. Effect on human health

vi. Effect ecosystem

vii. Ecological disturbance

There are different views regarding the effect of global warming on agriculture

NEGATIVE Effect

1. Effect of this change will vary for C3(i.e. wheat, rice, and beans) and C4(e.g. maize, millets, and sugarcane) plants.

2. As temperature increases with rising CO2 level, some crops may no longer be grown in certain rigions.

POSITIVE Effect

With increased CO2 concentration some plants will show increased photosynthesis,

Greater Root Production

Plant more trees

Cut down the current rate of CFCs and fossil fuel

Reduce beef production

Shift from coal to natural gas

Efficiently remove CO2 from smoke

Adopt sustainable agriculture
