Global warming evidence(?) and positive feedback loops

But some remember those frenzied forecasts. Following is but a small taste of a smorgasbord of baloney:

Al Gore once declared that "unless drastic measures to reduce greenhouse gases" were taken within the next decade, "the world will reach a point of no return," eventually suffering "a true planetary emergency." That was 13 years ago.

Gore is of course the same fellow who in the mid- to late-2000s kept telling us the Arctic Ocean would soon be ice-free. The ice, which is still there, had grown thicker and had wider coverage in 2014 than when Gore made his prediction. Earlier this year, before the growing season had ended, Wattsupwiththat reported the "2019 Arctic sea-ice extent is already higher than the previous four years and six out of the last 14 years."

In January 2009, former NASA scientist and corporate witch hunter James Hansen swore that the incoming president had a mere four years to save the world.

Later in the year, British Prime Minister Gordon Brown (the Thames, again) said there remained "fewer than 50 days to set the course of the next 50 years and more."

Also in 2009, 124 months ago, the prince of Wales worried out loud the world had "less than 100 months" to save itself.
2009 was a particularly looney year. Elizabeth May, leader of the Greens in Canada, wrote "we have hours to act to avert a slow-motion tsunami that could destroy civilization as we know it. … We need to act urgently. We no longer have decades; we have hours."

While speaking to then-Secretary of State John Kerry in May 2014, French Foreign Minister Laurent Fabius warned that "we have 500 days to avoid climate chaos." Nearly 1,900 days have passed since. The chaos is in the foreign minister's head.

In 2015, mayors from around the world signed a statement that said the "last effective opportunity to negotiate arrangements that keep human-induced warming below 2-degrees" Celsius had arrived.

Almost 20 years ago, in Y2K, the British Independent quoted a climate researcher who said in coming years the children of England "just aren't going to know what snow is." Thirteen years later, that same newspaper told readers to "stand by for icy blasts and heavy snow."

Commentary by Max:

Predictions of climate disaster have always rested upon the implausible assumption that earth's climate is an unstable equilibrium, when everything we know about earth's history and planetary systems indicates it's more likely to be a stable equilibrium. If heating led to further irreversible heating, the Earth would already have turned irreversibly into a furnace way back in the Medieval Warm Period. Climatology's arguments in favor of positive feedback loops are extraordinary claims, and we have yet to see extraordinary evidence. It's hotter than it used to be but in all likelihood this is about as hot as it's ever going to get, and the history of the past two decades bears that out because it's no longer getting even hotter--there is no temperature-driven positive feedback loop.

Also carbon dioxide has diminishing returns. At some point you're already capturing about all the energy in the CO2 bands, and increasing CO2 levels cease to matter (in terms of temperature at least--high CO2 levels do still make air feel less fresh, while increasing plant growth rates, and extremely high CO2 levels can give you a headache or eventually even kill you).
