There are no effects from Global warming.
Global warming , also referred to as climate change , is the observed century-scale rise in the average temperature of the Earth 's climate system and its related effects .. Earth.

Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years .. instrumental temperature record. instrumental temperature record. paleoclimate.

In 2013 , the Intergovernmental Panel on Climate Change -LRB- IPCC -RRB- Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century .

These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing .. Future climate change and associated impacts will differ from region to region around the globe .. region to region. regional effects of global warming. Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics .. effects. effects of global warming. rising sea levels. sea level rise. precipitation. precipitation ( meteorology ). subtropics. subtropics.

Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years .. climate system. climate. effects. effects of global warming. inertia.

Avoiding dangerous climate change. Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change ..
