Future climatic change as well as related effects varies from region-to-region across the world. The impact of global temperature increase includes sea level rises, subtropical deserts’ probable expansion, and change in pattern and amount of precipitation. While warming will be strongest in Arctic coupled with continuing glaciers retreat, sea ice, and permafrost, there are other likely global warming effects such as extreme weather conditions like ocean acidification, heavy rainfall, heat waves, droughts, as well as species extinctions because of changing temperature. These adverse effects of global warming provide sufficient that government efforts in tightening environmental regulations are not anchored on cheap propaganda but on realistic issues that deserve urgent redress. To human beings, there are food security threats arising from low crop yields as well as habitat loss from inundation. For these reasons, governments ought to implement policy responses towards global warming.
