Gates argues that both governments and businesses have parts to play in fighting global warming. While he acknowledges that there is a tension between economic development and sustainability, he posits that accelerated innovation in green technology, particularly sustainable energy, would resolve it. He calls on governments to increase ...
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.
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 of 2021 the remaining carbon budget for a 50-50 chance of staying below 1.5 degrees of warming is 460 bn tonnes of CO 2 or 11 + 1 ⁄ 2 years at 2020 emission rates. [14] Global average greenhouse gas per person per year in the late 2010s was about 7 tonnes [15] – including 0.7 tonnes CO 2 eq food, 1.1 tonnes from the home, and 0.8 tonnes from transport. [16]
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. [28]
Climate change has become a concern for a number of disciplines due to its potentially catastrophic impacts on environmental systems, wildlife, nature, and humans.Climate change poses a serious threat to the global economy as economic development, especially in the West, has been largely dependent on the extraction and burning of fossil fuels since the Industrial Revolution.

The December 2020 Lancet Countdown review concluded that trends in 2020 showed "a concerning paucity of progress" in numerous sectors, including "a continued failure to reduce the carbon intensity of the global energy system, an increase in the use of coal-fired power, and a rise in agricultural emissions and premature deaths from excess red meat consumption.
Climate crisis is a term that is used to describe global warming and climate change and their effects. This term and the term climate emergency have been used to emphasize the threat of global warming to Earth's natural environment and to humans, and to urge aggressive climate change mitigation and transformational adaptation.
