Climate Change and its Impact

Climate change is clearly already causing enormous human suffering and economic costs, in the here and now. According to the United Nations, adopting sustainable energy would not only help combat these ills of climate change; it would also save millions of lives per year.




Discussions of climate change are often abstract. Yet with a dangerous increase in destructive and a proliferation in large-scale droughts, its adverse effects are becoming more and more profound.
At the World Future Energy Summit 2016 last week, U.N. Secretary-General Ban Ki-moon spoke about the importance of moving toward sustainable energy sources. Ban stressed that adopting sustainable energy technologies will help combat climate change and prevent the global temperature from exceeding the two degree Celsius goal. An estimated 1 billion people around the world do not have access to electricity. Adopting sustainable energy technologies could help provide access to these people to the resources.

There are two main policy responses to climate- change mitigation and adaptation. Mitigation addresses the root causes, by reducing greenhouse gas emissions, while adaptation seeks to lower the risks posed by the consequences of climatic changes. Both approaches will be necessary, because even if emissions are dramatically decreased in the next decade, adaptation will still be needed to deal with the global changes that have already been set in motion.

Adaptation measures may be planned in advance or put in place spontaneously in response to a local pressure. They include large-scale infrastructure changes – such as building defenses to protect against sea-level rise or improving the quality of road surfaces to withstand hotter temperatures – as well behavioral shifts such as individuals using less water, farmers planting different crops and more households and businesses buying flood insurance.
