Climate change and global warming and the rising amounts of CO 2 in the atmosphere have contributed to ocean warming and ocean acidification. The ocean has acted as a carbon sink for earth for millennia and is currently slowing the rate of global warming through the sequestration of carbon. This comes at a cost however as the oceans are ...
One of the problems of environmental issues is about the sea level rise. Sea level rise is an increase in the level of the world's oceans due to the effects of global warming. Burning fossil fuels is one of the causes of global warming because it releases carbon dioxide and other heat-trapping gasses into the atmosphere.
The key conclusions of Working Group I [11] were: . An increasing body of observations gives a collective picture of a warming world and other changes in the climate system (The global average surface temperature has increased over the 20th century by about 0.6 °C; Temperatures have risen during the past four decades in the lowest 8 kilometres of the atmosphere; Snow cover and ice extent have ...
The Special Report on Emissions Scenarios (SRES) is a report by the Intergovernmental Panel on Climate Change (IPCC) that was published in 2000. The greenhouse gas emissions scenarios described in the Report have been used to make projections of possible future climate change.
Avoiding this future warming will require a large and rapid reduction in global greenhouse gas emissions. The ongoing warming will increase risks and stresses to human societies, economies, ecosystems, and wildlife through the 21st century and beyond, making it imperative that society respond to a changing climate.
Working Group I, dealing with the scientific aspects of climate, stated that carbon dioxide remains the most important contributor to anthropogenic forcing of climate change; projections of future global mean temperature change and sea level rise confirm the potential for human activities to alter the Earth's climate to an extent unprecedented in human history; and the long time-scales ...
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.
It is extremely likely (95–100% probability) [13] that human influence was the dominant cause of global warming between 1951 and 2010. [12] Working Group II: "Increasing magnitudes of [global] warming increase the likelihood of severe, pervasive, and irreversible impacts". [14] "
