Per the now widely discredited CAGW hypothesis, which the UN's IPCC agency still promotes, rapidly increasing and catastrophic global temperatures are the result of human CO2 emissions - but as the global warming science facts produced by the U.S. NOAA agency confirms, accelerating and dangerous warming is not happening

Over the first four months of 2012, the continental U.S. has experienced very warm and enjoyable temperatures. Yet, despite the warming of the U.S., the rest of the globe experienced temperatures below average, as the chart depicts.
The adjacent chart plots the average temperature anomaly for the first four months over the last 17 years ("why 17?" you ask) and the average CO2 level for those same four months. The green curve represents the five-year average of the temperature anomalies and the black CO2 curve is also a five-year average.
Obviously, over the last 17 years, hundreds of billions of tons of human CO2 emissions from consumption of fossil fuels has caused the atmospheric CO2 levels to increase dramatically. Yet global temperatures are not rapidly warming but instead have been basically flat to a minor cooling over that time period.
