Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
To limit global warming to less than 1.5 °C global greenhouse gas emissions needs to be net-zero by 2050, or by 2070 with a 2 °C target. [271] This requires far-reaching, systemic changes on an unprecedented scale in energy, land, cities, transport, buildings, and industry.
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
Global warming potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere over a specific time period, relative to carbon dioxide (CO 2). [ 1 ] : 2232 It is expressed as a multiple of warming caused by the same mass of carbon dioxide (CO 2 ).
The global print and paper industry accounts for about 1% of global carbon dioxide emissions. [177] Greenhouse gas emissions from the pulp and paper industry are generated from the combustion of fossil fuels required for raw material production and transportation, wastewater treatment facilities, purchased power, paper transportation, printed ...
This new global interconnectedness and free flow of information has radically altered notions of other cultures, conflicts, religions and taboos. Now, social movements can and do form at a planetary scale. Evidence, if more were needed, of the link between social and environmental global change came with the 2008–2009 global financial crisis ...
First, the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole, which in turn holds in a frozen mass of Arctic air.Second, if the North Atlantic drift were to shut down [broken anchor], that barrier would fail, releasing a flood of frozen air into the Northern Hemisphere, causing a sudden and drastic temperature shift.
A global warming hiatus, [1] also sometimes referred to as a global warming pause [2] or a global warming slowdown, [3] is a period of relatively little change in ...
