That's part of the problem, climate change is a fact, that it is being caused by man is not, but it is presented as fact. There is not enough computer power in the world to compute an accurate prediction several years out, even while leaving out several global alterations like El Nino.
As God's stewards of the Earth, there are genuine and important environmental issues to address. But there should be no hysteria, there should be no alarmist teens signing a pledge that they won't have children until the gov't does something about climate change!
Climates change, but why they change doesn’t seem to be as straightforward as we’re often told.
The mass hysteria around Climate Change are warning of catastrophic environmental failure AGAIN. If you really think this one is any different than similar warnings of the last 50 years of failures, follow the link:
“Wrong Again: 50 Years of Failed Eco-pocalyptic Predictions.”
Some of these failed apocalyptic scenarios include:
In 1967, Stanford biologist Paul Ehrlich said it was “already too late” to stop a long famine period that would be at its worst by 1975.
In 1970, many scientists predicted a new ice age by the 21st century, the depletion of all the rivers in the US, and a lack of oxygen in the atmosphere.
In 1978, scientists said there was “no end in sight” to a 30-year cooling trend.
In 1989, rising sea waters were thought to obliterate nations by the year 2000.
In 2008, the Arctic was expected to be free of sea ice in the summer by 2018.
And we’ll see if a 2004 prediction that Britain will have the same climate as Siberia by 2024 will come true.
In answer to your question, there is no way possible to be sure of anything about the weather several years out, let alone decades. First and foremost, nobody can foretell the future. When these OPINIONS are claimed and reported and asserted as fact is when people become alarmist, irrational, weeping at the altar of science, when it's gov't funding it. Keep it going, only Big Brother can save you. Create the crisis then bring on the cure, all about power and control, not the environment. The EPA is the fastest growing entity within federal gov't, expanding offices no longer fit in DC, growing fatter every day, big sway.
