Its there in the public domain if one opens their eyes just for a little while.

Bringing inconvenient evidence and facts into the debate again Hugh, how very dare you !

It's still all just based upon theories.


Whenever they make specific predictions, then tend not to be true. Instead the policy nowadays is to make vague predictions which cover every possible outcome. Eg Global Warming has become Climate Change.

Theories !! Its happening now old chap, Australia is on fire and we're getting constant floods. Time to wake up.

And fires have never happened before? Especially when you go planting lots of trees in urban areas which help spread the fire. Or cuddly Koalas eat too many of the young tree shoots and end up killing off the trees. Those are facts.

All science is at some point based on theory. Better science refutes current science. Nothing else

I liken those who deny climate change as to those that dismissed Copernicus.

Gravity is just a theory* - try ignoring it...

Just a theory

"Just a Theory": 7 Misused Science Words

"A word like 'theory' is a technical scientific term," said Michael Fayer, a chemist at Stanford University. "The fact that many people understand its scientific meaning incorrectly does not mean we should stop using it. It means we need better scientific education."

Climate-change deniers and creationists have deployed the word "theory" to cast doubt on climate change and evolution.
"It's as though it weren't true because it's just a theory," Allain said.

That's despite the fact that an overwhelming amount of evidence supports both human-caused climate change and Darwin's theory of evolution.
Part of the problem is that the word "theory" means something very different in lay language than it does in science: A scientific theory is an explanation of some aspect of the natural world that has been substantiated through repeated experiments or testing. But to the average Jane or Joe, a theory is just an idea that lives in someone's head, rather than an explanation rooted in experiment and testing.

And before that it was a new ice age. Before that, we just had extreme weather events. Remember 'dustbowl America'? The North Sea floods of 1953?

Every extreme weather event is now apparently due to global warming. Just how gullible is the general population? The 'proof' of man made global warming lies in the fact that it has been repeated on the media so many times that it must be true.

And still we need to address the fact that carbon represents only 0.04% of the atmosphere. Funny, that.

The "proof" is that 97% of climate scientists agree, and the ones who fund the disagreements are the energy companies who benefit from nothing being done to mitigate climate change (as it would impact their profit margin).

Why carbon dioxide matters
Carbon dioxide is a greenhouse gas: a gas that absorbs heat. Warmed by sunlight, Earth’s land and ocean surfaces continuously radiate thermal infrared energy (heat). Unlike oxygen or nitrogen (which make up most of our atmosphere), greenhouse gases absorb that heat and release it gradually over time, like bricks in a fireplace after the fire goes out. Without this natural greenhouse effect, Earth’s average annual temperature would be below freezing instead of close to 60°F. But increases in greenhouse gases have tipped the Earth's energy budget out of balance, trapping additional heat and raising Earth's average temperature.

Carbon dioxide is the most important of Earth’s long-lived greenhouse gases. It absorbs less heat per molecule than the greenhouse gases methane or nitrous oxide, but it’s more abundant and it stays in the atmosphere much longer. And while carbon dioxide is less abundant and less powerful than water vapor on a molecule per molecule basis, it absorbs wavelengths of thermal energy that water vapor does not, which means it adds to the greenhouse effect in a unique way. Increases in atmospheric carbon dioxide are responsible for about two-thirds of the total energy imbalance that is causing Earth's temperature to rise.

Another reason carbon dioxide is important in the Earth system is that it dissolves into the ocean like the fizz in a can of soda. It reacts with water molecules, producing carbonic acid and lowering the ocean's pH. Since the start of the Industrial Revolution, the pH of the ocean's surface waters has dropped from 8.21 to 8.10. This drop in pH is called ocean acidification.

A drop of 0.1 may not seem like a lot, but the pH scale is logarithmic; a 1-unit drop in pH means a tenfold increase in acidity. A change of 0.1 means a roughly 30% increase in acidity. Increasing acidity interferes with the ability of marine life to extract calcium from the water to build their shells and skeletons.

Past and future carbon dioxide
Natural increases in carbon dioxide concentrations have periodically warmed Earth’s temperature during ice age cycles over the past million years or more. The warm episodes (interglacials) began with a small increase in sunlight due to a tiny wobble in Earth’s axis of rotation or in the path of its orbit around the Sun.

That little bit of extra sunlight caused a little bit of warming. As the oceans warmed, they outgassed carbon dioxide—like a can of soda going flat in the heat of a summer day. The extra carbon dioxide in the atmosphere amplified the initial warming.

Based on air bubbles trapped in mile-thick ice cores (and other paleoclimate evidence), we know that during the ice age cycles of the past million years or so, carbon dioxide never exceeded 300 ppm. Before the Industrial Revolution started in the mid-1700s, the global average amount of carbon dioxide was about 280 ppm.

By the time continuous observations began at Mauna Loa Volcanic Observatory in 1958, global atmospheric carbon dioxide was already 315 ppm. On May 9, 2013, the daily average carbon dioxide measured at Mauna Loa surpassed 400 ppm for the first time on record. Less than two years later, in 2015, the global amount went over 400 ppm for the first time. If global energy demand continues to grow and to be met mostly with fossil fuels, atmospheric carbon dioxide will likely exceed 900 ppm by the end of this century.

I have a higher definition of 'proof' than that.

Everyone believed the sun went around the Earth at one time. Didn't make it true, though, did it?

I’m sure you didn’t mean to phrase it that way but the way you’ve put it is a logical fallacy - an appeal to popularity. Everyone may believe something, but everyone may be wrong.

The proof of catastrophic anthropogenic climate change is not in the strength of belief in it but in the mountain of observable evidence that has caused 97% of scientists to affirm that it exists, is a problem, and must be remedied urgently.

[Sephiroth]

As OB says, the world goes through these cycles. Anything urgent should be dealt with by the politicians and scientists - which, of course it won't until the last minute.

Climate change has always been a fact.

Atm, the planet is almost as cold as its ever been in its entire 4 billion year existance.

The climate has always been changing, it was much warmer than now millions of years ago (when man did not exist, to blame).
