It had become clear that achieving global agreement for effective action to limit global warming would be much more challenging. [ note 2 ] [ 4 ] [ 8 ] Some politicians, such as Arnold Schwarzenegger with his slogan "terminate pollution", say that activists should generate optimism by focusing on the health co-benefits of climate action.
Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming is a 2017 book created, written, and edited by Paul Hawken about climate change mitigation. Other writers include Katharine Wilkinson , and the foreword was written by ( hardback edition) Tom Steyer and ( paperback ) Prince Charles .
With 21% of global methane emissions, cattle are a major driver of global warming. [ 225 ] : 6 When rainforests are cut and the land is converted for grazing, the impact is even higher. In Brazil, producing 1 kg of beef can result in the emission of up to 335 kg CO 2 -eq. [ 226 ] Other livestock, manure management and rice cultivation also emit ...
As reported by the Intergovernmental Panel on Climate Change (IPCC), most of the observed global warming since the mid-20th century is very likely due to human-produced emission of greenhouse gases and this warming will continue unabated if present anthropogenic emissions continue or, worse, expand without control.
For example, the IPCC Special Report on Global Warming of 1.5 °C was a "key scientific input" into the 2018 United Nations Climate Change Conference. [4] Various pathways are considered in the report, describing scenarios for mitigation of global warming.
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [29] [30] [31] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes.

[96] [97] Adding biochar may increase the soil-C stock for the long term and so mitigate global warming by offsetting the atmospheric C (up to 9.5 Gigatons C annually). [98] In the soil, the biochar carbon is unavailable for oxidation to CO 2 and consequential atmospheric release. However concerns have been raised about biochar potentially ...
