1) He's talking about the USA, not the world:One way to measure trends in extreme weather is to compare the number of state record high and low temperatures by decade. Many more state high temperature records were set in the 1930s than in recent decades. Even more surprising,“since 1960, there have been more all-time cold records set than hot records in each decade.”
http://www.earthfiles.com/news.php...Well, a really good way to look at global warming is to look at what it has done to warm temperature records. And if you didn't have a warming Earth, then you would have the same number of new cold records as you would warm records in any given year on average. Well, what we've been seeing for quite some time now is more and more hot records relative to cold records. And the last two years have really been screaming in terms of how many more hot records we've had than cold records.
2) Not even true in the US any more:
http://www.climatecentral.org/news/heat-wave-...The June to July heat wave finally began to ebb on Saturday, but not before breaking thousands of warm temperature records across the country. In many cases, records that had stood since the Dust Bowl era of the 1930s have been equaled or exceeded, and this event is likely to go down in history as one of America's worst early summer heat waves.
