“This figure shows carbon dioxide emissions from 1990 to 2011 for different regions of the world. These totals do not include emissions or sinks related to land-use change or forestry. Inclusion of land-use change and forestry would increase the apparent emissions from some regions while decreasing the emissions from others.” – United States Environmental Protection Agency
"This figure shows worldwide greenhouse gas emissions by sector from 1990 to 2010. For consistency, emissions are expressed in million metric tons of carbon dioxide equivalents. These totals include emissions and sinks due to land-use change and forestry.
“This figure shows worldwide emissions of carbon dioxide, methane, nitrous oxide, and several fluorinated gases from 1990 to 2010. For consistency, emissions are expressed in million metric tons of carbon dioxide equivalents. These totals include emissions and sinks due to land-use change and forestry.” – United States Environmental Protection Agency
“This figure shows concentrations of carbon dioxide in the atmosphere from hundreds of thousands of years ago through 2013, measured in parts per million (ppm). The data come from a variety of historical ice core studies and recent air monitoring sites around the world. Each line represents a different data source.” - United States Environmental Protection Agency
“This figure shows how annual average temperatures worldwide have changed since 1901. Surface data come from a combined set of land-based weather stations and sea surface temperature measurements. Satellite measurements cover the lower troposphere, which is the lowest level of the Earth’s atmosphere. “UAH” and “RSS” represent two different methods of analyzing the original satellite measurements. This graph uses the 1901–2000 average as a baseline for depicting change.

UN special rapporteur on the right to food champions agroecology as sustainable alternative to existing framework
(Reuters) - China is poorly prepared to tackle the impact of climate change that presents a serious threat to the country, thanks to a lack of planning and public awareness, the government said on Monday.
Climate change will pose sharp risks to the world’s food supply in coming decades, potentially undermining crop production and driving up prices at a time when the demand for food is expected to soar, scientists have found.
The world's oceans are becoming acidic at an "unprecedented rate" and may be souring more rapidly than at any time in the past 300 million years.
In their strongest statement yet on the issue, scientists say acidification could increase by 170% by 2100.

Africa faces climate adaptation costs in the range of $7 billion to $15 billion per year by 2020, and that figure could rise to around $350 billion annually by 2070 if global warming exceeds 2 degrees Celsius, a U.N. report said on Tuesday.
