Chapter 10 of the IPCC 2013 report shows that it is all but "virtually certain" that climate change and each part of the climate system is changing from human actions since the 1950s. It lays out every aspect: atmosphere, ocean, cryosphere, and extremes/weather. There is very strong evidence that the climate system is reacting to human activity. Many cited studies show that the atmosphere is reacting to anthropogenic forces by warming globally. Following the atmosphere, the ocean is also heating up thanks to anthropogenic influences. Not only is the ocean warming, but the salinity is decreasing because of an increase of fresh water from melting ice. This increase of freshwater is also causing the sea level to rise. Oxygen content is also decreasing in the ocean and it is linked to burning fossil fuels. The ocean is also shown to becoming more acidic. In the cryosphere, sea ice is being melted away at a quick rate (50% less in 2012 from 2005). The ocean and cryosphere are directly related and are also caught in feedback loops. These feedback loops are causing the negative processes from anthropogenic influences to speed up exponentially. When looking at extremes and weather, there was not good information. The overall outcome is that increased precipitation and drought are both more likely than not caused by anthropogenic influences. To conclude, this chapter has shown that GHGs and other human actions are causes the climate to change rapidly in many different ways.
