A friend notes that this winter was a particularly cold one and states that this is evidence that global warming is not occurring. Evaluate the validity of this statement.
Answer ) The cold winter as an evidence do not justify that global warming is not occuring.Global warming is not just association with increase in temperature but also it associated with extreme climate occurance.Several factors play a vital role in climate change and global warming leading to increases in temperature and changes in precipitation patterns globally. The consequences of global climate changes are difficult to predict owing to the complexity of and incomplete insight into several atmospheric processes and interactive relationships among different environmental variables, such as temperature, radiation, water availability, soil salinity, and soil nutrition. These worldwide fluctuations in climatic variability are of serious concern to agricultural productivity and is an impact of global warming.
Global warming and associated changes in the hydrological cycle and sea-level rise are expected to cause serious negative impact on natural ecosystems, human health, and economy. It is predicted that climate change will disrupt ecosystems and will result in loss of species diversity, as many species will be not be able to adapt to rapidly changing environmental conditions. Some ecosystems, such as tropical montane, mangrove forest, and Arctic ecosystems, are likely to disappear because warmer climate or sea-level rise will not support them. In the high latitudes, warming will cause degradation of permafrost and an increase of methane release from wetlands. Because methane is the next important greenhouse gas after CO2, this will also amplify global warming.
