Since the late 1800′s, the global average temperature has increased about 0.4 to 0.8 degrees C. Current pollution trends put us on a path to 6°C of warming this century when 4°C or more would trigger the breakdown of civilization as we know it. To be closer to 2°C than 4°C we need to make global emissions start to decline before 2020. Scientists worry that human societies and natural ecosystems might not adapt to rapid climate changes. As an ecosystem consists of the living organisms and physical environment in a particular area, global warming could cause much harm. Countries throughout the world, therefore, drafted an agreement called the Kyoto Protocol to help limit it. Politicians and scientists agree we must limit global warming to less than 2°C to prevent runaway climate change.
The entire problem in the natural system is only due to the pandemonium activities. If the sun asks why to give heat and light and plants raise question why to give oxygen, what could be in the nature? – No one can imagine. So within dutifulness there is beautifulness. Obviously the challenges to be faced in this decade are very dreadful and challenging. If we, therefore, change the way of thinking, all the problems will be sorted out without any difficulty. The only way to make the world livable for our future generations, hence, is the revolution in way of thinking.
