This is due to constant increase in concentration of green house gases in the atmosphere by human activities, such as deforestation, industrialization, increased burning of fossil fuel, mining, exhaust from automobiles and other anthropogenic activities.
Impact of Green house effect and global warming:
Due to global warming rise of 1.5degree C temperature can adversely affect the food production; biological activity, increased breeding of pest and diseases.
Some of the harmful effects are listed below.
Melting of ice
Rise in sea level
Submergence of coastal wet lands
Change in crop patterns
Dispersion of toxic chemicals
Effects on ecosystem and bio diversity
Change in hydrological cycle
Change in soil characteristics
Change in wind movement
Effects on human health-distribution of vector borne diseases like malaria, filarial etc. higher temperature, humidity increase respiratory skin disease.
Depletion of ozone layer.
Causes acid rain.
Measures to control or limit Global Warming Some of the measures to check Global warming are:
Cutting the emission ofCO2, reducing the usage of fossil fuel and inverting energy conservation measures and utilizing renewable energy sources Wind, solar, hydro power roller etc.
Implementing of reforestation programme to enhance the natural sinks of CO2.
Adoption of sustainable agriculture.
Removing atmosphere CO2 by utilizing photosynthetic algal.
Cut down the current rate of use of CFC and fossil fuel.
Efficient energy management.
Shift to renewable energy resource.
Increase in plantation of trees.
Trap and use methane as a fuel.
Adopt sustainable agriculture.
Stabilize population growth.
Control measures to remove CO2.
