limate change is any long-term significant change in the “average weather” that a given region experiences. Average weather may include average temperature, precipitation and wind patterns. It involves changes in the variability or average state of the atmosphere over durations ranging from decades to millions of years. These changes can be caused by dynamic process on Earth, external forces including variations in sunlight intensity, and more recently by human activities. Climate changes reflect variations within the Earth's atmosphere, processes in other parts of the Earth such as oceans and ice caps, and the effects of human activity. The external factors that can shape climate are often called climate forcing and include such processes as variations in solar radiation, the Earth's orbit, and greenhouse gas concentrations. Climate change is one of the biggest effects on human being now and will be onwards. Global warming of the climate system now is unequivocal, according to many different kinds of evidence. So we need to use the web of evidence; climate science to observation and look at the evidence to show us about the risk from climate change. We should care about climate science, because it informs us about the risk from climate change and input into public policy. For example, when we use climate science we can get the evidence to show the effects of the global warming are especially evident in the planets Polar Regions. Arctic sea ice extent and volume has been decreasing foe the past several decades.
Climate is always changing and many of the observed changes noted above are beyond what can be explains by the natural variability of the climate.
Climate change will increasingly alter the rules for doing business. There will be winning industries and winning companies. There will also be losing ones. Large mainstream investors such as pension funds want to know which companies are the likely winners, and which are the riskier investments in a low-carbon economy. What are the risks that climate change poses for companies and what are companies doing to manage those risks? As with all types of risks, “enterprises in the same industry, facing similar risks, will often choose different risk management actions because different managements have different risk strategies, objectives and tolerances. Risks related to climate change may be physical, regulatory, reputational or legal. Some companies face mitigation risks related to their obligations and expectations about reducing their emissions of greenhouse gases (GHG). The risks faced by others may be related more to the impact of climate change on their business operations and the need to adapt accordingly (adaptation-related risks). Companies’ effectiveness in identifying and addressing climate change risks (and opportunities) and their implications for business strategy is itself an important and distinguishing
