Portal. : Climate change/Selected article/9. Pictured left: Image of the largest Antarctic ozone hole ever recorded (September 2006) Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, and a much larger springtime decrease in ...
Individual action on climate change. A demonstrator taking action through climate activism at the People's Climate March (2017) in Washington, D.C. Individual action on climate change is about personal choices that everyone can make to reduce the greenhouse gas emissions of their lifestyles. Such personal choices are related to the way people ...
Deforestation and climate change. Deforestation in the tropics – given as the annual average between 2010 and 2014 – was responsible for 2.6 billion tonnes of CO 2 per year. That was 6.5% of global CO 2 emissions. Deforestation is a primary contributor to climate change, [ 1][ 2] and climate change affects the health of forests. [ 3]
Main sources of global methane emissions (2008-2017) according to the Global Carbon Project [ 40] Methane emissions come from livestock, manure, rice cultivation, landfills, wastewater, and coal mining, as well as oil and gas extraction. [ 41] Nitrous oxide emissions largely come from the microbial decomposition of fertiliser.

China observed a ground average temperature increase of 0.24 °C (0.43 °F) per decade from 1951 to 2017, exceeding the global rate. The average precipitation of China was 641.3 millimetres (25.25 in) in 2017, 1.8% more than the average precipitation of previous years. There was an annual increase in concentrations of carbon dioxide from 1990 ...
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 ...
