Annual temperature: The historical time series of statewide annual temperatures in Colorado begins in 1895. Over the entire record, there has been an upward trend, which has resulted in temperatures in the early 21st century being about 2ºF warmer than temperatures 100 years ago. Despite this long-term rise however, the record continues to be largely dominated by annual and decadal-scale variability. The run of recent warm years comes on the heels of a period of falling temperatures that extended from the early 1940s through the early 1980s. Previous to then, temperatures warmed rapidly from the 1910s through the 1930s, long before high levels of industrial CO2 emissions. The highest annual average statewide temperature was observed in 1934. |

Annual temperature: The historical time series of statewide annual temperatures in Utah begins in 1895. Over the entire record, there has been an upward trend, which has resulted in temperatures in the early 21st century being about 2ºF warmer than temperatures 100 years ago. Despite this long-term rise however, the record is largely dominated annual and decadal-scale variability. The run of recent warm years comes on the heels of a period of relatively steady temperatures that extended from the early 1950s through the early 1980s. Previous to then, temperatures warmed rapidly from the 1910s through the 1940s. The highest annual average statewide temperature was observed in 1934. |

Concern over the potential impacts of climate change led South Carolina Governor Mark Sanford to issue an Executive Order on February 16, 2007 to create a Climate, Energy and Commerce Advisory Committee tasked with developing an Action Plan for the state of South Carolina in order to mitigate carbon dioxide emissions. Governor Sanford cited as a need for such action the “potential effects of global climate change…including more frequent and severe storm events and flooding; sea level rise, water supply disruption, agricultural crop yield changes and forest productivity shifts; water and air quality degradation; and threats to coastal areas, tourism, and infrastructure - could significantly impact South Carolina's economy, level of public expenditures, and quality of life.” |

Although two polar bear subpopulations (Western Hudson Bay and Southern Beaufort Sea) no longer appear to be viable due to reduction in sea ice habitat, polar bears as a species do not appear to be threatened by extinction in the foreseeable future from either a demographic or an ecological perspective. Ecological perspectives that suggest the reductions to survival and recruitment rates for two populations (Western Hudson Bay and Southern Beaufort Sea) have occurred because of a long-term decline in sea ice due to climate warming. These populations occur where summer ice coverage is seasonal (WH) or divergent (SB). |
