The AGW hypothesis states that human CO2 emissions will cause the world to warm, with the the globe's polar areas being especially vulnerable to rapid warming, due to CO2. Without any hesitation, not waiting for any actual empirical evidence, global-warming scientists and activists predicted that Antarctica will melt, causing incredible sea level increases.
It has not come true, and is not about to happen based on real world, scientific reality. (click on image to enlarge)
Luckily for the world's inhabitants, the CO2-crazed "scientists," alarmists and gore-profiteers have been spectacularly wrong. The historical Antarctica temperatures and atmospheric CO2 levels provide proof that temperatures change significantly without a direct relationship to CO2 levels.
Per the Vostok ice cores, southern polar temperatures have made swings of 3 degrees Celsius during historical times while related CO2 levels have barely budged. And when 20th century human CO2 emissions increased dramatically? Vostok polar ice sheet temperatures have stayed flat. (Note: The mean temperature for Vostok over the ice core history has been a minus 55 degrees Celsius. The ice sheet won't be melting even if there were swings in temperature of 20 degrees.)
Note: More evidence that the climate has experienced wide temperature changes prior to any industrial/consumer CO2 emissions, similar to what the Vostok ice cores reveal.
