Record Highs vs Record Lows — 9:1 in 2012

 
One of those very inconvenient facts that global warming deniers have to avoid like the plague is that record highs are far outnumbering record lows these days. In the US, from the beginning of 2012 through late June, the ration was 9:1, Climate Central recently reported. In the image below, you can actually watch the ratio climb over the years:

Here’s more from Climate Central on this matter, and on what we’re heading towards with the “business as usual” scenario:

As the climate has warmed during the past several decades, there has been a growing imbalance between record daily high temperatures in the contiguous U.S. and record daily lows. A study published in 2009 found that rather than a 1-to-1 ratio, as would be expected if the climate were not warming, the ratio has been closer to 2-to-1 in favor of warm temperature records during the past decade (2000-2009). This finding cannot be explained by natural climate variability alone, the study found, and is instead consistent with global warming.

When you look at individual years, the imbalance can be more stark. For example, through late June 2012, daily record highs were outnumbering record daily lows by a ratio of 9-to-1.The study used computer models to project how the records ratios might shift in future decades as the amount of greenhouse gases in the air continues to increase. The results showed that the ratio of daily record highs to daily record lows in the lower 48 states could soar to 20-to-1 by mid-century, and 50-to-1 by 2100.

How are global warming deniers going to try to brush that one away?
