Description

This lecture by the instructor from the Finnish Environmental Institute covers the impact of Short-Lived Climate Pollutants (SLCPs) like black carbon and methane on the Arctic climate. It discusses the main sources of these pollutants globally and in the Arctic Council member States, as well as the emission mitigation strategies and their effects on the Arctic climate. The lecture emphasizes the sensitivity of the Arctic region to SLCPs, the importance of global mitigation efforts, and the potential temperature reductions achievable through SLCP emission reductions. It also addresses specific Arctic emission sources such as shipping, flaring, and the goals set by the Arctic Council to reduce black carbon emissions. The conclusion highlights the need for policy actions to reduce emissions and emphasizes the interconnectedness of the Arctic climate with the global climate system.

Climate change

In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane.

Climate change mitigation

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 burning 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.

Climate change denial

Climate change denial or global warming denial is dismissal or unwarranted doubt that contradicts the scientific consensus on climate change. Those promoting denial commonly use rhetorical tactics to give the appearance of a scientific controversy where there is none. Climate change denial includes doubts to the extent of how much climate change is caused by humans, its effects on nature and human society, and the potential of adaptation to global warming by human actions.

Politics of climate change

The politics of climate change results from different perspectives on how to respond to climate change. Global warming is driven largely by the emissions of greenhouse gases due to human economic activity, especially the burning of fossil fuels, certain industries like cement and steel production, and land use for agriculture and forestry. Since the Industrial Revolution, fossil fuels have provided the main source of energy for economic and technological development.

Emission intensity

Life-cycle greenhouse gas emissions of energy sources An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).
