Patrick Albert Moore is a Canadian industry consultant, former activist, an early member and past president of Greenpeace Canada. Since leaving Greenpeace in 1986, Moore has criticized the environmental movement for what he sees as scare tactics and disinformation, saying that the environmental movement "abandoned science and logic in favor of emotion and sensationalism". Greenpeace has criticized Moore, calling him "a paid spokesman for the nuclear industry, the logging industry, and genetic engineering industry" who "exploits long-gone ties with Greenpeace to sell himself as a speaker and pro-corporate spokesperson".
Climate change mitigation is action to limit climate change by reducing emissions of greenhouse gases or removing those gases from the atmosphere. The recent rise in global average temperature is mostly due to emissions from unabated burning of fossil fuels such as coal, oil, and natural gas. Mitigation can reduce emissions by transitioning to sustainable energy sources, conserving energy, and increasing efficiency. It is possible to remove carbon dioxide from the atmosphere by enlarging forests, restoring wetlands and using other natural and technical processes. Experts call these processes carbon sequestration. Governments and companies have pledged to reduce emissions to prevent dangerous climate change in line with international negotiations to limit warming by reducing emissions.
Coal Pollution Mitigation, sometimes also known as Clean Coal, is a series of systems and technologies that seek to mitigate health and environmental impact of coal; in particular air pollution from coal-fired power stations, and from coal burnt by heavy industry. Clean Coal primarily focuses on removing sulfur dioxide (SO2) and nitrogen oxides (NOx), the most important gasses which cause acid rain; and particulates which cause visible air pollution, illness, and premature deaths. It also reduces fly ash and reduces emissions of radioactive materials. Mercury emissions can be reduced up to 95%. Capturing carbon dioxide emissions from coal is also being pursued.
Business action on climate change includes a range of activities relating to climate change, and to influencing political decisions on climate change-related regulation, such as the Kyoto Protocol. Major multinationals have played and to some extent continue to play a significant role in the politics of climate change, especially in the United States, through lobbying of government and funding of climate change deniers. Business also plays a key role in the mitigation of climate change, through decisions to invest in researching and implementing new energy technologies and energy efficiency measures.
The Virgin Earth Challenge was a competition offering a $25 million prize for whoever could demonstrate a commercially viable design which results in the permanent removal of greenhouse gases out of the Earth's atmosphere to contribute materially in global warming avoidance. The prize was conceived by Richard Branson, and was announced in London on 9 February 2007 by Branson and former US Vice President Al Gore.
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Carbon dioxide, from burning fossil fuels such as coal, oil, and natural gas, is one of the most important factors in causing climate change. The largest emitters are China followed by the US, although the United States has higher emissions per capita. The main producers fueling the emissions globally are large oil and gas companies. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but have been consistent among all greenhouse gases. Emissions in the 2010s averaged 56 billion tons a year, higher than any decade before. Total cumulative emissions from 1870 to 2017 were 425±20 GtC from fossil fuels and industry, and 180±60 GtC from land use change. Land-use change, such as deforestation, caused about 31% of cumulative emissions over 1870–2017, coal 32%, oil 25%, and gas 10%.
Climate stabilization wedges are used to describe possible climate change mitigation scenarios and their impact, through the grouping of different types of interventions into "wedges" representing potential decreases in CO2 emissions. When stacked on top of each other, wedges form a "stabilization triangle" that represents the estimated amount of carbon that needs to be removed from the atmosphere to flatten carbon emissions and prevent atmospheric carbon from doubling. This framework is used to organize complex information about mitigation strategies for presentation to policy makers and the public, with the goal of stimulating both technological change and policy actions to deploy precommercial and existing technologies.
This article discusses the debate surrounding China's economic responsibilities in terms of climate change mitigation and efforts to mitigate climate change within China.
Greenhouse gas emissions by Australia totalled 533 million tonnes CO2-equivalent based on greenhouse gas national inventory report data for 2019; representing per capita CO2e emissions of 21 tons, three times the global average. Coal was responsible for 30% of emissions. The national Greenhouse Gas Inventory estimates for the year to March 2021 were 494.2 million tonnes, which is 27.8 million tonnes, or 5.3%, lower than the previous year. It is 20.8% lower than in 2005. According to the government, the result reflects the decrease in transport emissions due to COVID-19 pandemic restrictions, reduced fugitive emissions, and reductions in emissions from electricity; however, there were increased greenhouse gas emissions from the land and agriculture sectors.
Carbon dioxide removal (CDR), also known as carbon removal, greenhouse gas removal (GGR) or negative emissions, is a process in which carbon dioxide gas is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products. In the context of net zero greenhouse gas emissions targets, CDR is increasingly integrated into climate policy, as an element of climate change mitigation strategies. Achieving net zero emissions will require both deep cuts in emissions and the use of CDR. CDR can counterbalance emissions that are technically difficult to eliminate, such as some agricultural and industrial emissions.
William Happer is an American physicist who has specialized in the study of atomic physics, optics and spectroscopy. He is the Cyrus Fogg Brackett Professor of Physics, emeritus, at Princeton University, and a long-term member of the JASON advisory group, where he pioneered the development of adaptive optics. From 1991 to 1993, Happer served as director of the Department of Energy's Office of Science as part of the George H.W. Bush administration. He was dismissed from the Department of Energy in 1993 by the Clinton Administration after disagreements on the ozone hole.
Climate change in Europe has resulted in an increase in temperature of 2.3 °C (2022) in Europe compared to pre-industrial levels. Europe is the fastest warming continent in the world. Europe's climate is getting warmer due to anthropogenic activity. According to international climate experts, global temperature rise should not exceed 2 °C to prevent the most dangerous consequences of climate change; without reduction in greenhouse gas emissions, this could happen before 2050. Climate change has implications for all regions of Europe, with the extent and nature of impacts varying across the continent.
A Representative Concentration Pathway (RCP) is a greenhouse gas concentration trajectory adopted by the IPCC. Four pathways were used for climate modeling and research for the IPCC Fifth Assessment Report (AR5) in 2014. The pathways describe different climate change scenarios, all of which are considered possible depending on the amount of greenhouse gases (GHG) emitted in the years to come. The RCPs – originally RCP2.6, RCP4.5, RCP6, and RCP8.5 – are labelled after a possible range of radiative forcing values in the year 2100. The higher values mean higher greenhouse gas emissions and therefore higher global temperatures and more pronounced effects of climate change. The lower RCP values, on the other hand, are more desirable for humans but require more stringent climate change mitigation efforts to achieve them.
The United Nations Climate Change Conference, COP19 or CMP9 was held in Warsaw, Poland from 11 to 23 November 2013. This is the 19th yearly session of the Conference of the Parties to the 1992 United Nations Framework Convention on Climate Change (UNFCCC) and the 9th session of the Meeting of the Parties to the 1997 Kyoto Protocol. The conference delegates continue the negotiations towards a global climate agreement. UNFCCC's Executive Secretary Christiana Figueres and Poland's Minister of the Environment Marcin Korolec led the negotiations.
Since the 1970s, American fossil fuel and energy corporation ExxonMobil has engaged in climate research focussing on global warming. It later began lobbying, advertising, and grant making, some of which were conducted with the purpose of delaying widespread acceptance and action on global warming.
Climate change in France has caused some the greatest annual temperature increases registered in any country in Europe. The 2019 heat wave saw record temperatures of 46.0 °C. Heat waves and other extreme weather events are expected to increase with continued climate change. Other expected environmental impacts include increased floods due to both sea level rise and increased glacier melt. These environmental changes will lead to shifts in ecosystems and affect local organisms. Climate change will also cause economic losses in France, particularly in the agriculture and fisheries sectors.
The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is a carbon offset and carbon reduction scheme to lower CO2 emissions for international flights, to curb the aviation impact on climate change.
Greenhouse gas emissions by China are the largest of any country in the world both in production and consumption terms, and stem mainly from coal burning in China, including coal-fired power stations, coal mining, and blast furnaces producing iron and steel. When measuring production-based emissions, China emitted over 14 gigatonnes (Gt) CO2eq of greenhouse gases in 2019, 27% of the world total. When measuring in consumption-based terms, which adds emissions associated with imported goods and extracts those associated with exported goods, China accounts for 13 gigatonnes (Gt) or 25% of global emissions.
Greenhouse gas emissionsbyRussia are mostly from fossil gas, oil and coal. Russia emits 2 or 3 billion tonnes CO2eq of greenhouse gases each year; about 4% of world emissions. Annual carbon dioxide emissions alone are about 12 tons per person, more than double the world average. Cutting greenhouse gas emissions, and therefore air pollution in Russia, would have health benefits greater than the cost. The country is the world's biggest methane emitter, and 4 billion dollars worth of methane was estimated to leak in 2019/20.
Fit for 55 is a package by the European Union designed to reduce the European Union's greenhouse gas emissions by 55% by 2030. It is part of the unions strategy of the European green deal presented first in December 2019.
