The Culture of Climate Change Science and Skepticism

While the IPCC’s consensus approach acknowledges uncertainties, defenders of the IPCC consensus have expended considerable efforts in the ‘boundary work’ of distinguishing those qualified to contribute to the climate change consensus from those who are not [4]. These efforts have characterized skeptics as small in number [13], extreme [50], and scientifically suspect [14]. These efforts create temptations to make illegitimate attacks on scientists whose views do not align with the co...

 We Need to Take into Account Evolutionary Traps

Human-induced rapid environmental change (HIREC; e.g., climate change or exotic species) has caused global species declines. Although behavioral plasticity has buffered some species against HIREC, maladaptive behavioral scenarios called ‘evolutionary traps’ are increasingly common, threatening the persistence of affected species. Here, we review examples of evolutionary traps to identify their anthropogenic causes, behavioral mechanisms, and evolutionary bases, and to better forecast form...

 Climate Change Science is Based on an 1896 Paper

Our understanding that increasing carbon dioxide levels in the atmosphere could change the climate is not new. The relationship between carbon dioxide, water vapor, and climate was first laid out in detail in 1896 by the Swedish physicist Svante Arrhenius, who estimated that a doubling of carbon dioxide levels would cause global warming of 4.9° to 6.1°C. In his landmark paper, Arrhenius reported that "a simple calculation shows that the temperature in the arctic regions would rise about 8°...

 1890 Statement on Climate Change

The number of hypotheses and theories about climate change are numerous. Quite naturally they have caught the public attention, as any proof of past climactic change points to the possibility of future climate change, which inevitably will have significant implications for global economics.

 Evidence of Global Warming in Just the Past 12 Months

Is the climate crisis real? Yes, of course it is. Pause for a moment to consider these events of just the past 12 months: • Heat. According to NASA, 2010 was tied with 2005 as the hottest year measured since instruments were first used systematically in the 1880s. Nineteen countries set all-time high temperature records. One city in Pakistan, Mohenjo-Daro, reached 128.3 degrees Fahrenheit, the hottest temperature ever measured in an Asian city. Nine of the 10 hottest years in history h...
