The difficulty of developing sound strategies for responding to climate change has become complex. Some of them are related to the physical science of climate change. But, understanding of climate change also increases many social, economic, ethical, and political challenges. There are some of the unique and important challenges created by climate change. It mainly includes the following:
Projecting future climate change requires understanding various linkages among human activities, greenhouse gas (GHG) emissions, the response of the climate system, changes in atmospheric composition, and impacts on human and natural systems.
In this chain, the basic links can be easily understood. As a result, the actions reduce emissions or the vulnerabilities of human and natural systems. These must present in probability and qualitative terms rather than as certain predictions.
It takes very long time periods for some aspects of the climate system to respond fully to the bottom of Form changes in atmospheric GHG concentrations. This is because the oceans can easily store a large amount of heat so that it takes a long time for the climate system to warm up in response to changes in GHG concentrations. It creates an impact on the rise of sea level and the melting of ice sheets which can further take several centuries to express fully.
Some GHGs removes from the atmosphere, but CO2 remains longer. Today, approximately 20 percent of the CO2 emitted. Hence, it is a failure to reduce GHG emissions in the near-term that will “lock-in” a certain amount of future climate change.
GHG emissions built into societal infrastructure to a large extent. It also includes human habits and organizational routines, few of them have changed quickly. Market incentives affecting capital investments do not consider consequences on a longer time scale. Also, it does not consider making major reductions in GHG emissions and preparing to adapt to the effects of climate change.
An issue of specific concern related to the equipment and infrastructure leads to GHG emissions. There are often strong economic pressures to continue the use of such equipment and infrastructure. It makes substantial emission reductions within the next few decades.
Different regions and populations will experience different impacts in terms of climate change. It is different in their ability to adapt and tolerate the impacts, and judgments based on the potential risks created by climate change. For instance, coastal communities are vulnerable to serious disruptions. It could show the risks of climate change. Actions that are taken in response to climate change will also pose different types of risks to different regions, sectors, and populations.
Many complex characteristics of climate change reach across scientific, political, economic, psychological, and other dimensions. These problems do not solve before one can move ahead with making choices and taking action to address climate change. Instead, these can inherent features of climate change that must recognize and understand in order to craft sound response strategies.
