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".
A carbon footprint (or greenhouse gas footprint) is a calculated value or index that makes it possible to compare the total amount of greenhouse gases that an activity, product, company or country adds to the atmosphere. Carbon footprints are usually reported in tonnes of emissions (CO2-equivalent) per unit of comparison. Such units can be for example tonnes CO2-eq per year, per kilogram of protein for consumption, per kilometer travelled, per piece of clothing and so forth. A product's carbon footprint includes the emissions for the entire life cycle. These run from the production along the supply chain to its final consumption and disposal.
Business action on climate change is a topic which since 2000 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.
Friends of Science(FoS) is a non-profit advocacy organization based in Calgary, Alberta, Canada. The organization rejects the established scientific consensus that humans are largely responsible for the currently observed global warming. Rather, they propose that "the Sun is the main direct and indirect driver of climate change," not human activity. They argued against the Kyoto Protocol. The society was founded in 2002 and launched its website in October of that year. They are largely funded by the fossil fuel industry.
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 (GHG) emissions from human activities intensify the greenhouse effect. This contributes 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 United States. The United States has higher emissions per capita. The main producers fueling the emissions globally are large oil and gas companies. Emissions from human activities 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 2022 were 703 GtC, of which 484±20 GtC from fossil fuels and industry, and 219±60 GtC from land use change. Land-use change, such as deforestation, caused about 31% of cumulative emissions over 1870–2022, coal 32%, oil 24%, and gas 10%.
Carbon pricing is a method for governments to mitigate climate change, in which a monetary cost is applied to greenhouse gas emissions in order to encourage polluters to reduce fossil fuel combustion, the main driver of climate change. A carbon price usually takes the form of a carbon tax, or an emissions trading scheme (ETS) that requires firms to purchase allowances to emit. The method is widely agreed to be an efficient policy for reducing greenhouse gas emissions. Carbon pricing seeks to address the economic problem that emissions of CO2 and other greenhouse gases are a negative externality – a detrimental product that is not charged for by any market.
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) is a process in which carbon dioxide is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products. This process is also known as carbon removal, greenhouse gas removal or negative emissions. CDR is more and more often integrated into climate policy, as an element of climate change mitigation strategies. Achieving net zero emissions will require first and foremost deep and sustained cuts in emissions, and then—in addition—the use of CDR. In the future, CDR may be able to 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.
350.org is an international environmental organization addressing the climate crisis. Its stated goal is to end the use of fossil fuels and transition to renewable energy by building a global, grassroots movement.
Climate drawdown refers to the future point in time when levels of greenhouse gas concentrations in the atmosphere stop climbing and start to steadily decline. Drawdown is a milestone in reversing climate change and eventually reducing global average temperatures. Project Drawdown refers to a nonprofit organization which tries to help the world reach drawdown and stop climate change. In 2017, a publication titled "Drawdown" highlighted and described different solutions and efforts available to help reach this goal.
From the 1980s to mid 2000s, ExxonMobil was a leader in climate change denial, opposing regulations to curtail global warming. For example, ExxonMobil was a significant influence in preventing ratification of the Kyoto Protocol by the United States. ExxonMobil funded organizations critical of the Kyoto Protocol and seeking to undermine public opinion about the scientific consensus that global warming is caused by the burning of fossil fuels. Of the major oil corporations, ExxonMobil has been the most active in the debate surrounding climate change. According to a 2007 analysis by the Union of Concerned Scientists, the company used many of the same strategies, tactics, organizations, and personnel the tobacco industry used in its denials of the link between lung cancer and smoking.
A carbon budget is a concept used in climate policy to help set emissions reduction targets in a fair and effective way. It examines the "maximum amount of cumulative net global anthropogenic carbon dioxide emissions that would result in limiting global warming to a given level". It can be expressed relative to the pre-industrial period. In this case, it is the total carbon budget. Or it can be expressed from a recent specified date onwards. In that case it is the remaining carbon budget.
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 and curb the aviation impact on climate change. CORSIA uses market-based environmental policy instruments to offset CO2 emissions: aircraft operators have to purchase carbon credits from the carbon market.
Climate change in Taiwan has caused temperatures in Taiwan to rise by 1.4 degrees Celsius the last 100 years. The sea around Taiwan is to rise at twice the rate of the global sea level rise. The government pledged to reduce emissions by 20% in 2030 and 50% in 2050, compared to 2005 levels.
China's greenhouse gas emissions are the largest of any country in the world both in production and consumption terms, and stem mainly from coal burning, including coal power, 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. According to the Carbon Majors Database, Chinese state coal production alone accounts for 14% of historic global emissions.
The Netherlands is already affected by climate change. The average temperature in the Netherlands rose by more than 2 °C from 1901 to 2020. Climate change has resulted in increased frequency of droughts and heatwaves. Because significant portions of the Netherlands have been reclaimed from the sea or otherwise are very near sea level, the Netherlands is very vulnerable to sea level rise.
This article documents events, research findings, scientific and technological advances, and human actions to measure, predict, mitigate, and adapt to the effects of global warming and climate change—during the year 2020.
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 union's strategy of the European Green Deal presented first in December 2019.
