- A survey conducted in 2007 by George Mason University of U.S. scientists who have expertise in climate science (not just a scientific background) what they think. 97% of the 489 respondents agreed that “global average temperatures have increased” during the past century. That’s up from 60% in 1991. [click, Image 2] 84% believe human activities are causing the warming, and only 5% disagree. So the survey does indicate the bulk of climate scientists—those most knowledgeable about the field—now agree that human activity contributes to global warming.
- The oceans will continue their rise in the coming century. The IPCC’s best estimates range from a few inches to a few feet by 2100. If the rise is 2 feet, the US could lose 10,000 square miles, If they rise three, they will inundate Miami and most of coastal Florida. Sea-level rise also increases coastal erosion and the loss of coastal wetlands, and saltwater spoils freshwater drinking supplies. Coastal populations become even more vulnerable to storm surge and flooding. Considering that half of the world’s population lives near coasts, sea-level rise is a serious concern. The big unknown in all this is how much the planet’s ice sheets will melt. Warming of the climate system is unequivocal Very high confidence that global average net effect of human activities since 1750 one of warming Human-caused warming over last 30 years has likely had a visible influence on many physical and biological systems Continued GHG emissions at or above current rates would cause further warming and induce many changes in the global climate system during the 21 st century that would very likely be larger than those observed during the 20 th century.”

- The burning of fossil fuels and other human activities are increasing the levels of carbon dioxide and other heat-trapping gases in the atmosphere, causing global average temperatures to rise. Ü The Northeast is already experiencing changes consistent with global warming: rising temperatures, decreasing snow cover, and earlier arrival of spring. Ü Due to emissions in the recent past, average temperatures across the Northeast are projected to rise another 2.5 to 4 degrees Fahrenheit (°F) in winter and 1.5°F to 3.5°F in summer above historic levels over the next several decades. The extent and severity of climate change beyond mid- century, however, will be determined by emissions choices we make now—in the Northeast and around the world. Ü If emissions remain high, average temperatures across the Northeast are projected to rise, by late this century, 8°F to 12°F above historic levels in winter and 6°F to 14°F in summer. Cities across the Northeast are projected to average 20 days per summer over 100°F and some (such as Philadelphia and Hartford, CT ) could average nearly 30 such days. The length of the winter snow season could be cut in half across Maine, New Hampshire, northern New York, and Vermont. Ü Smaller climate-related changes can be expected if the world follows the lower-emissions pathway used in this assessment—typically about half the change expected under the higheremissions scenario. By late-century, for example, average temperature is projected to increase 5°F to 8°F in winter and 3°F to 7°F in summer under the lower-emissions scenario. Most cities are projected to average only a few days over 100°F. NYC : Today’s 100-Year Flood Could Occur Every 10 Years under the Higher-Emissions Scenario40 The light blue area in these maps depicts today’s FEMA 100-year flood zone for New York City (i.e., the area of the city that is expected to be flooded once every 100 years). With additional sea-level rise by 2100 under the higheremissions scenario, this approximate area is projected to have a 10 percent chance of flooding in any given year; under the lower-emissions scenario, a 5 percent chance. As the close-up shows, critical transportation infrastructure located in the Battery could be flooded far more frequently unless protected. The 100-year flood at the end of the century (not mapped here) is projected to inundate a far larger area of New York City, especially under the higher-emissions scenario.

- Companies providing goods and services that tackle climate change now form a bigger industry grouping than the global software and biotech sectors combined. HSBC said that 390 companies around the world could now be classed as providing goods or services that tackle climate change. Companies include large multinationals (SIEMANS, PHELPS) and large renewable companies. 4% of global market cap. Up from 2% last year.
- The value of the global carbon market surged 84 percent to $118 billion in 2008 The value of the global carbon market surged 84 percent to $118 billion in 2008 despite the worldwide financial crisis, reports New Carbon Finance. Data from the market research firm shows that transaction volume for carbon dioxide emissions allowances reached four billion tons for the year, an increase of 42 percent over 2007. The average price across all transactions rose to $29 per ton of CO2 from $23. New Carbon Finance says it expects the market to reach $150 billion in 2009, despite falling carbon prices amid the global economic slowdown. The European Union Allowance (EUA) market accounted for 70 percent of carbon emissions trading volume and 80% of value in 2008. The market share of Secondary Certified Emission Reductions (CERs) — credits sanctioned under the Clean Development Mechanism — reached 13 percent in 2008, up from 8 percent in 2007. "Our analysis suggests a total market size of $150bn by year-end 2009,"
