How can climate change be mitigated
The last time levels were that high was about three to five million years ago, during the Pliocene Epoch. Because we are already committed to some level of climate change, responding to climate change involves a two-pronged approach:.
Adaptation — adapting to life in a changing climate — involves adjusting to actual or expected future climate. The goal is to reduce our vulnerability to the harmful effects of climate change like sea-level encroachment, more intense extreme weather events or food insecurity.
It also encompasses making the most of any potential beneficial opportunities associated with climate change for example, longer growing seasons or increased yields in some regions. Throughout history, people and societies have adjusted to and coped with changes in climate and extremes with varying degrees of success.
Climate change drought in particular has been at least partly responsible for the rise and fall of civilizations. Modern life is tailored to the stable climate we have become accustomed to. As our climate changes, we will have to learn to adapt. The faster the climate changes, the harder it could be. While climate change is a global issue, it is felt on a local scale. Cities and municipalities are therefore at the frontline of adaptation.
In the absence of national or international climate policy direction, cities and local communities around the world have been focusing on solving their own climate problems. They are working to build flood defenses, plan for heatwaves and higher temperatures, install water-permeable pavements to better deal with floods and stormwater and improve water storage and use.
According to the report on Climate Change Impacts, Adaptation and Vulnerability page 8 from the United Nations Intergovernmental Panel on Climate Change, governments at various levels are also getting better at adaptation. It requires the deliberate intervention in the climate system with the aim of curbing global warming. This could be done by pumping sulphur aerosols into the high reaches of the atmosphere, where they would have similar reflective properties to the ash released naturally by volcanoes.
As the name suggests, this would combine the burning of biomass, such as wood, for energy and then piping the CO2 into rocks. In theory, you could begin to remove emissions that have already been accumulated in the atmosphere. But critics of this approach warn that the technology is unproven and could give reluctant countries an excuse not to cut emissions.
