The global change of climate has already had effects which are observable on the environment in general. For instance, glaciers have shrunk, ice which is present on lakes and rivers is breaking up earlier than expected, animal and plant ranges have also shifted and trees are actually flowering faster (Yang, Kun et al. 2014, 80). The effects which were predicted by scientists in the past which will be as a result of climate change are now visible i.e. accelerated rise of the sea level, loss of the sea ice and heat waves which are more intense. Scientists are having more confidence that the world temperatures will continue to escalate for many more years coming, hugely due to the high greenhouse gases which are emitted by human activities (Melillo 2014, 5-10).
The IPCC i.e. Intergovernmental Panel on Climate Change, which comprise of more than 1000 scientists from the US and other parts of the world, predicts a rise of temperature of about 2.5 to 10 degrees Fahrenheit in the next coming century (Climate change 2014). According to this board, the extent of the effects of change in climate on individual areas will basically vary over a long period of time and with the ability of various environmental and societal systems to adapt or mitigate to the change. Also the IPCC have forecasted that increases in the worldwide mean temperature of about less than 1.7 to about 5.4 degrees Fahrenheit above the 1990 levels will be able to produce beneficial effects in particular areas and the harmful ones in other regions(Yang, Kun et al. 2014, 80).
The worldwide climate has been predicted to continue changing in the coming years. The magnitude of the change of climate will highly depend mainly on the amount of the heat trapping gases which are emitted globally and the way sensitive the climate of Earth is to the emissions. The temperatures are predicted to continue to rise (Yang, Kun et al. 2014, 80). The frost-free season will continue to lengthen. Since the 1980s, the length of the frost-free season has been escalating nationally. With the huge increases taking place in the western US which affect the agriculture and the ecosystems. Across the US, the enlarging season is predicted to continue being long.
Since 1900, the average US precipitation has increased. The projections of the future climate in the US has suggested that the current trend towards the increased heavy precipitation events will be continuous(Melillo et al. 2014, 5-10). Also, the climate change will result to more heat waves and droughts. The summer temperatures are seen to continue increasing and also the reduction of the soil moisture is projected in the summer. Also, the hurricanes will become more intense and stronger. Climate change will result to the rise of the sea level by 2100. The Arctic is also likely to become free of ice (Melillo et al. 2014, 5-10).
