What is Climate?

Climate refers to the general patternof atmospheric or weather conditions,seasonal variations and weatherextremes in a region, averaged overa long period —at least 30 years.

Adaptation Factors responsible for climate on earth are:

l

l Earth's rotation, shape, inclination and distance between earth and sun

l Oceanic currents

l Human activities

Climate and Weather?Weather is the atmospheric condition found in a place at any particular time. The various atmospheric conditions that constitute weather include temperature, varying pressure, hot and cold air currents, formation of clouds, precipitation, solar radiation, etc.

Climate on the other hand refers to the general pattern of atmospheric or weather conditions, seasonal variations and weather extremes in a region, averaged over a long period—at least 30 years.

What is atmosphere?

Atmosphere is a blanket of gases surrounding the earth

Layer Extent Temperature

Troposphere 14.5 km from earth’s surface 17º C to -52º C

Stratosphere Up to 50 km from earth's surface -52º C to -3º C

Mesosphere Up to 85 km from earth's surface -3º C to -93º C

Thermosphere Up to 600 km from earth's surface 1,727º C

atmosphere contains Greenhouse gases (GHGs), which forms a blanket around earth's surface.

l GHGs absorb some part of the heat from sunlight and trap it near the earth's surface.

l This natural mechanism is known as Greenhouse Effect.

What happens if GHGs level in the atmosphere increases?l

l Earth's temperature rises causing warming of the planet

l Increase in ambient temperature of the earth leads to change in climate

More heat is retained on the earth's surface

Melting of glaciers and polar ice caps will increase water in seas. This along with expansion of sea water due to warming would rise sea level, and it would submerge small islands and coastal areas.

lights and fan when not required

l Prevent waste— Recycle, Reuse, Refuse what you do not need(plastic bags, extra packaging)

l Use public transport, carpool and walk/bicycle for short distances

l Eat local and in-season food

l Harvest rain water

l Plant saplings

Conserve energy at home and school by switching off
