Climate Change Science
Changes OverTime
Prior to 1800 –the Earth’s climate was not a compelling topic
 Today - it is a major concern although the causes are hotly disputed
 Climate Change Science is one example where there has been significant growth in knowledge over the last 200 years


Climate Change Science
Effects of Increased Knowledge


The Discovery and Proof of:
◦ Green House Effect
 1824 - Greenhouse effect discovered by Fourier
 1859 - John Tyndall confirmed Fourier discovery by confirming that H2O and CO2 absorb infrared heat
 1955 - Isotopic signature of industrial based CO2 emissions discovered by Hans
Suess
 1958/1960’s - Charles David Keeling proved CO2 was increasing in the atmosphere



Led to:
◦ Adoption and Use of Climate Modeling
 1970’s/80’s Suke Manabe and James Hansen began modeling climate projections



Resulting in :
◦ Organizations Established to Study Climate Change and its Impacts





National Center for Atmospheric Research (NCAR)
Global Institute for Space Studies (GISS)
National Oceanic and Atmospheric Administration (NOAA)
Intergovernmental Panel on Climate Change (IPCC)

Climate Change Science
Example 1: Green House Effect







Discovered in 1924 - Natural layer of gases covering Earth like a thermal blanket
Proven in 1959 - CO2 concentration, increased by humans, blocks escaping heat forces climate change
2007 - Intergovernmental Panel on Climate
Change (IPCC) concluded 90% probability human produced greenhouse gasses caused observed increase in Earth’s temperatures
2011 - Current observations not explained by solar activity (Solar Irradiance)

How China Rises

...How China rises What lessons can be drawn from China's spectacular and sustained economic growth? As Hu Jintau remarked at the 17th Congress of the Chinese Communist Party, the period since the previous Congress five years ago has been extraordinary. China's economic achievements have been arousing not only astonishment and admiration but also some anxiety. In the past twelve months alone, The People's Republic of China (PRC) has overtaken Canada as the biggest source of imports to the USA, and overtaken the USA as the biggest source of imports to the European Union. Concern about the low level of investment in Africa has been displaced by concern about the effects of the high level of Chinese investment in Africa; there is now even anxiety about the effects of investment by Chinese state-owned firms into the Western economies. The Chinese Communist Party is also expressing concerns. The themes of its 2007 Congress included protection of the environment and the achievement of social harmony. According to some estimates, China has displaced the USA as the world's biggest source of greenhouse gases. Inequality is rising as fast as pollution: China now has over 800 individuals with a personal wealth of more than a hundred million US dollars each, up from 500 in 2006; while the average income in rural areas of China is 480 dollars per year. Made in China. Hu Jintau's remark on the extraordinary nature of the most recent years can be faulted in only one sense: China has...
