Question

analyze climate change and the answer would give the environmental problem as a government representative.

Answer 1

Making IPCC as the base, we can say that present climate change is mostly due to human impact. although there have come many volcanoes and earthquakes causing various climate change phenomenon. Pleistocene glaciation and interglacial periods all gesture towards it but there are some evidences presented by IPCC currently in this regards -

1. By 2100 AD, earth temperature will rise between 1 degree to 3.1 degree celsius. Within last 140 yrs till 2000, temperature increased between .3 and .6 degree celsius. In the 20th century alone (after industrial revolution and globalisation), this rise in temperature is .4 degree celsius and 20th century is the warmest century till now.

2. The warmest decades were 1910-45 (world war period) and 1976-2000 (globalisation period)

3. Year 1998 was the warmest year and 1990 was the warmest decade.

4. heat waves in Australia and Europe

5. Rapid melting of ice and spread of infectious diseases in other than tropics.

Hence, seeing all this, one can say that global warming is due to human impact.

Hence, the international organisations around the world and the natonal governments in the countries are working to fight against climate change. Montreal protocol, paris peace climate, conference of Parties etc are the manifestations of it. It is because of all these steps we are observing reduction in the size of ozone hole now. But still many steps to be taken as a responsibility. But it is not only the job of governments, even the citizens should understand this responsiblity and should reduce food wastage, electricity consumption (by using CFLs) etc.
