        Effects of climate change The  effects of climate change  span the impacts on  physical environment ,  ecosystems  and human societies due to ongoing human-caused  climate change . The future impact of climate change depends on how much nations reduce  greenhouse gas emissions  and  adapt  to climate change.  Effects that scientists predicted in the past—loss of sea ice, accelerated  sea level rise  and longer, more intense  heat waves —are now occurring.  The changes in climate are not expected to be uniform across the Earth. In particular, land areas change more quickly than oceans, and northern high latitudes change more quickly than the  tropics . There are three major ways in which global warming will make changes to regional climate: melting ice, changing the  hydrological cycle  (of evaporation and precipitation) and changing  currents in the oceans .

                  FOOD WASTAGE Defining Food Wastage Communities across Europe and North America are establishing food waste reduction programs to tackle the issue at hand. Measuring the impact of these programs is key to their success and effectiveness. Well-defined terms will facilitate the development of food wastage benchmarks to help measure the effectiveness of waste reduction policies and programs. It is a communication challenge to convey different concepts of wasted food. Does “edible” or “useable” or  “avoidable” adequately convey the concept that perfectly good food has been allowed to go to waste?  Some would argue that rotten food is no longer “edible” and is, therefore, not wasted food (but still food waste in the broader sense).  To avoid the problem of different interpretations of wasted food, WRAP established the following set of definitions governing food waste (WRAP, 2008): Avoidable:  Food and drink thr...
