Ice ages and tectonic movement would be considered slow, and volcanic eruptions and changes in solar heating would be relatively fast. Please note that the axes are logarithmic. Also, the plotted line is drawn to assist in seeing the relationship between speed, size, and duration of climate change. In this figure, human-caused climate change falls within natural variability. Projections of human influence, however, may place the human-caused climate change outside what is considered natural. http://climate-expeditions.org/public/human-impacts- on-climate-change.html

- 16. “What do we know today about how global temperature changes? “The temperature of the air near the surface has been measured by land, sea and satellite instruments, very accurately since the 1970s and fairly accurately since the late 19th century (black curve in GRAPH A, below). Four main influences are known, and combining these gives quite a good match to the observations (orange curve in A). The known influences are: irregular “El Niño” fluctuations in the upwelling of deep cold waters in the tropical Pacific Ocean, which cool or warm the air for a few years (purple curve in B); sulfate smog particles emitted in volcanic eruptions, such as El Chichón in 1982 and Pinatubo in 1991, which bring temporary cooling (blue curve); a quasi-regular cycle in the Sun’s activity that changes the radiation received at Earth (green curve); and human ("anthropogenic") changes — primarily emission of carbon dioxide from fossil fuels, but also other greenhouse gases and pollution such as smoke, and land-use changes such as deforestation (red curve). Theorists can calculate the actual influence of each factor, but only approximately. The authors of the model shown in the graph adjusted the weights to give the best fit to the observations. In particular, the global heating since the 1970s can be explained only by humanity’s greenhouse gas emissions. Note, for example, how the temperature trend in the first decade of the 21st century was generally flat because an upward push by anthropogenic forces was temporarily offset by a downward pull as solar activity decreased and the oceans absorbed more heat than usual from the atmosphere (sea water temperatures in fact continued to rise).” http://www.aip.org/history/climate/summary.htm

- 28. The Precautionary Principle “…the “precau9onary principle” is a no9on which supports taking protec9ve ac9on before there is complete scien9fic proof of a risk; that is, ac9on should not be delayed simply because full scien9fic informa9on is lacking. The “precau9onary principle” or precau9onary approach has been incorporated into several interna9onal environmental agreements, and some claim that it is now recognized as a general principle of interna9onal environmental law.”

- 31. Intergovernmental Panel on Climate Change (IPCC) “The Intergovernmental Panel on Climate Change (IPCC) is the international body for assessing the science related to climate change. The IPCC was set up in 1988 by the World Meteorological Organization (WMO) and United Nations Environment Programme (UNEP) to provide policymakers with regular assessments of the scientific basis of climate change, its impacts and future risks, and options for adaptation and mitigation. IPCC assessments provide a scientific basis for governments at all levels to develop climate- related policies, and they underlie negotiations at the UN Climate Conference – the United Nations Framework Convention on Climate Change (UNFCCC). The assessments are policy-relevant but not policy-prescriptive: they may present projections of future climate change based on different scenarios and the risks that climate change poses and discuss the implications of response options, but they do not tell policymakers what actions to take.” http://www.ipcc.ch/news_and_events/docs/factsheets/FS_what_ipcc.pdf

The green box indicates the moderating influences of local environmental conditions on how climate change exposure pathways are manifest in a particular population. The gray box indicates that the extent to which the three categories of exposure translate to actual health burden is moderated by such factors as background public health and socioeconomic conditions, and adaptation measures. The green arrows at the bottom indicate that there may be feedback mechanisms, positive or negative, between societal infrastructure, public health, and adaptation measures and climate change itself… “ (courtesy of E.

For the United States, those include the Obama administration’s proposal to reduce greenhouse gas emissions from coal plants, which would go into effect in 2017. Experts said that in practice it should be possible to wring more emissions cuts from that and other climate-related measures without adding to costs.” -- HENRY FOUNTAIN and JOHN SCHWARTZ Nov. 12, 2014 New York Times http://mobile.nytimes.com/2014/11/13/world/climate-pact-by-us-and-china- relies-on-policies-now-largely-in-place.html?referrer&_r=0
