... Abstract. Climate change occurs on timescales ranging from annual changes associated with El Niño, through decadal changes, to multidecadal trends linked to global warming. It affects us all in our daily lives, impacts the performance of much of industry, and leads to billions of pounds of damage wo ...

... The Earth is warming. Almost the entire globe has warmed, including the land surface, oceans and atmosphere, while the extent of snow and ice cover has also decreased and sea level has risen. Global average surface temperature has increased by 0.85°C since 1880, and by about 0.6°C to 0.7°C since 195 ...
