Climate poll statement said to be incorrect

In an article May 14 regarding the idea that global warming is doubted by some, this was mentioned in the article;  “Americans who do not trust climate science were especially aware of and influenced by recent shifts in world temperature, and 2011 was tied for the coolest of the last 11 years.”

First, that is not true, and the big picture is the climate is getting considerably warmer in the past decade and over the past centuries as well.

The global average surface temperature in 2011 was the ninth warmest since 1880, according to NASA scientists. The finding continues a trend in which nine of the 10 warmest years in the modern meteorological record have occurred since the year 2000. The difference between 2011 and the warmest year in the GISS record (2010) is 0.22 degrees F (0.12 C). This underscores the emphasis scientists put on the long-term trend of global temperature rise. Because of the large natural variability of climate, scientists do not expect temperatures to rise consistently year after year. However, they do expect a continuing temperature rise over decades.

2011 marks the 35th consecutive year, since 1976, that the yearly global temperature was above average. The warmest years on record were 2010 and 2005, which were 0.64°C (1.15°F) above average.

Separately, the 2011 global average land surface temperature was the eighth warmest on record. The 2011 global average ocean temperature was 0.40°C (0.72°F) above the 20th century average of 16.1°C (60.9°F) and ranked as the 11th warmest on record.
