The 20th CBRNE Command is the United States Army headquarters for defense against Chemical, Biological, Radiological, Nuclear, and high-yield Explosives (CBRNE), headquartered on the site of the defunct Edgewood Arsenal chemical weapons production facility at Aberdeen Proving Ground in northern Maryland.
Climate change adaptation has tended to be more of a focus for local authorities, while national and international politics has tended to focus on mitigation. There have been exceptions – in countries that feel especially exposed to the effects of climate change, sometimes the focus has been more on adaptation even at national level. [37]
The Bush Administration changed its name to Climate Change Science Program as part of its U.S. Climate Change Research Initiative. The Administration envisioned "a nation and the global community empowered with the science-based knowledge to manage the risks and opportunities of change in the climate and related environmental systems".
The predecessor of the IPCC was the Advisory Group on Greenhouse Gases (AGGG). [18] Three organizations set up the AGGG in 1986. These were the International Council of Scientific Unions, the United Nations Environment Programme (UNEP), and the World Meteorological Organization (WMO).
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, [1] certain industries like cement and steel production, and land use for agriculture and forestry.
Therefore, they are considered to be feedbacks that change climate sensitivity. On the other hand, gases such as CO 2, tropospheric ozone, [21] CFCs and nitrous oxide are added or removed independently from temperature. Hence, they are considered to be external forcings that change global temperatures. [22] [23]: 742
A global climate regime is a global framework that aims at regulating the interaction of human activity with the global climate system, to mitigate global climate change. The framework for such a regime was developed by the United Nations Framework Convention on Climate Change , or UNFCCC for short.
The overall risks of climate change impacts can be reduced by limiting the rate and magnitude of climate change" [14] Working Group III: Without new policies to mitigate climate change, projections suggest an increase in global mean temperature in 2100 of 3.7 to 4.8 °C, relative to pre-industrial levels (median values; the range is 2.5 to 7.8 ...
