NASA Says Hotter Summers Since 1980 Caused by Global Warming: Is Global Warming Man-Made?

I am still waiting on the ice age I was told that was going to happen.

It's not man-made it's monster-made by politicians (accidently clicked yes). Plus um, do all those climatologists realize how much dirtier we were in the Industrial revolution?

Do you realize that all that dirty air full of particulates from coal and wood fires actually causes global dimming by blocking sunlight and has a cooling effect. C02 on the other hand acts like a blanket and traps heat in the atmosphere, not letting it escape into space.

We have been ''warming up'' since the last 'Big Eruption' in 1816, the 'year without a summer' and 99% of all climatic data has been collected since then.
Skewed data in other words, and then skewed again by the East Anglia Global Warming cult crowd.
There will be another big eruption, trust me.
Then what will your hockey stick say, Al Gore?

Really, does anyone think global warming is the result of some other catastrophe?

Who's SUVs caused the last four warm periods between the Ice ages?

could be meteor hit the earth, could be super volcano, could be methane gas escapes, the question is what has caused this one?

A super volcano would not bring on a warm period but instead a cooling period.
Your Hypothesis is highly unlikely since each cycle was about the same length.

The cause of this warm period could be Al Gore's carbon footprint. Mansion, house boat, limo, private jet............

The earths orbit of the sun is eliptical and sometimes the earth has been farther away from the sun, sometimes closer. That's what caused the end of some of the ice ages. At other times, as in the end of snowball Earth, it was massive volcanic eruptions that lasted for millions of years. Right now it's C02 emissions made by us.

No one has adequate data to make your conclusion. Case in point..........



Humanity only recently discovered Plate tectonics, We are still very ignorant as to the workings of the planet.





''Right now it's C02 emissions made by us''
So why doesn't Al Gore Change his behavior?

It is the most probable and obvious cause of global warming. CO2 can be easily measured in the atmosphere and since the beginning of the industrial age levels have risen by well over 30%.

Al Gore bashing is a bit old and totally irrelevant.

If we were in the period just after the last Ice age as things were warming up, do you really believe we would be able to stop the normal ebb and flow of the planet? The answer is no.
My point about the Mag Covers is that there is so much we still don't not know and you climate nazis 'matter of fact' attitude turns people off to your message.

My Question about Gore and his ilk is completely relevant, get over it.

This is what the "tipping point" is about. if we continue to pump warming CO2 into the atmosphere, warming the planet sufficiently to start melting perma-frosts in Canada and Siberia and releasing a lot of methane and the poles melt enough white ice to expose more black ocean, we will have triggered a climate process of warming we can't stop. We may even be very close or even at that point already. Meanwhile idiots such as yourself are still denying the science. And you'll still be doing it as the flood waters are lapping around your living room sofa ? Won't ya ? You dumbass.

''It is the most probable and obvious cause of global warming''
The case of ''global warming'' has not been proven for fuchs sake. Therefore it's ''climate change'', didn't you get the memo?

Global warming caused by humans burning fossil fuels has been accepted as the most probable cause. Climate change is referring to the weather extremes caused by a warmer atmosphere. You either accept what the vast majority of top climatologists say, as most people do, or you join the lunatic fringe of creationists and flat earthers and birthers and what have you.

Sorry, I don't share your religious beliefs.

Religion and science have nothing in common. Science does not require belief , just understanding. The laws of physics care nothing about human belief, they will carry on regardless of whether or not we exist, let alone believe.

Science requires proven facts. You are not there. You have incomplete data and much of it skewed by people with a predetermined out come. Get over it. What's more the scam artist solution of carbon credits does absolutely nothing to curb C0². Have a nice evening.

Nobody can absolutely prove it. You can only look at the data and come to the " most probable cause. " The consensus says it's CO2.
It's the most likely and obvious cause of warming and the warming correlates to the CO2 emissions. Therefore. . .

Evidence suggest C02 levels are the result, not the cause of warmer weather patterns.

Oh Pu -lease ! Duh ! What happens when a heatwave and a drought caused by a warming atmosphere, dry a forest out until it catches fire, producing CO2.. What happens when perma frost melts - methane is released. When oceans warm and methane hydrates gas off from the sea floor. The climate system is full of delicate buttons and levers and booby traps, and we're like a baby with a nuclear bomb, bashing at all the controls not knowing what we're doing to what, overloading all the systems.

C'mon. Even you must know what a dumb way of looking at it, that is.

You have made a very compelling case that high C02 levels are the result, not the cause of warmer weather patterns.

Once again you've missed the point. What caused the last ten thousand years of unusually steady climate ? CO2 below a certain level, produces a steady climate. Got that ? Now add a whole lot of CO2 to the system very quickly like over a fifty year period. . .and what happens, suddenly you get a de-stabilized climate that is volatile and explosive. A warmer atmosphere holds more moisture and produces incredibly heavy rain, which produces destructive flooding and super large storms. Heatwaves suck enormous amounts of water out of the sea and land creating droughts, and fire storms in one place, then dump it all at once in heavy rain fall areas, causing disasters. Ring any bells ? CO2 above a certain level creates it's own positive feed back loops. :
Raise CO2, the ice sheets melt at the poles, creating more dark ocean that absorbs the heat from the sun instead of white ice that reflects the sun back to space, (albido effect ), this creates more warming which melts more white ice etc.

Of course it's man-made. Burning fossil fuels has driven up CO2 levels above anything seen on this Earth in over a million years:


The effect is visible with the loss of ice at the poles. You don't need any thermometer readings to see the warming:

Concerning the bigger part of it, i think!

it's a ''warm'' phase right now

It could be. Pollution. But otherwise I think it's 'nature-made'

It's astonishing that to me how many people equate "believing overwhelming scientific consensus" with "being liberal".

The simple fact is that when people are told that their actions are having a negative affect on something or other they become indignant and chalk it up to some conspiracy amongst whatever group is making the claim.

In this case, it's those pesky scientists who have so much to gain by claiming that oil is bad. Oh wait, the oil industry has billions of dollars and pays scientists hefty sums to contradict any climate change data.

Let me be clear, I don't believe in climate change because I am a scientist. Chances are the nay-sayers here are not scientists either, but maybe they have a cousin who knows someone who knows a scientist that is a skeptic. Whatever. I believe it's true because people who know more than I do are saying it is.

I also think it's odd that skeptics find us to be egotistical. Like "how important you must think you are to believe that you have some sort of impact on the earth". To that I say "how arrogant you must be to believe you DON'T have some impact on the earth."

Well said.

We get our heat from the sun. That is why in most places the temperature begins to rise when the sun comes up. Increased sunspot activity is responsible for the fluctuations we get. Otherwise you couldn't explain high temperatures of a century ago and beyond... Duh.

Actually the temperature of the planet depends on two simple things:

1: Heat coming in (i.e. radiation from the sun);
2: Heat going out (the heat that the sun-warmed Earth radiates away to space).

We have no control over the sun's output but we do have control over the amount of heat the Earth loses to space, because that is very sensitive to the composition of the atmosphere. We have increased the concentration of the most important greenhouse gas by 40%, which is a huge change to the composition of Earth's atmosphere, and means that less heat is radiated away to space, and therefore more remains to heat up the land and oceans, to melt ice, to make the atmosphere moister, to amplify droughts and heatwaves, to energise storms and to exacerbate torrential rain, blizzards and flooding.

We're now pushing the Earth's climate back towards those high temperatures of the past that you mentioned, and if we don't do something about it, we're going to be living in the kind of hothouse world the dinosaurs experienced 65 million years ago. That's bad news for human civilisation.

All of that is conjecture. More rain, droughts,.. Those things have always been around and no reason to think a few degrees warmer will make it far worse or better. Since we cannot turn the thermostat down on a dime any serious attempts to cool the planet could backfire if the sun's part in all of this were to emit less radiation. We would just be doubling down on the wrong hand. More people will die during an ice age than during global warming. Unless those dinosaurs you mentioned were to make a comeback.

Well you make some good points but the sun itself is actually remarkably stable. We're in far more danger from human influences on the climate than from tiny fluctuations in solar irradiance. I don't think a few degrees is going to be as benign as you suggest.

''the sun itself is actually remarkably stable''
Wrong.
The Sun goes through cycles lasting approximately 11 years that include phases with increased magnetic activity, more sunspots, and more solar flares.

''We're in far more danger from human influences on the climate than from tiny fluctuations in solar irradiance''
Wrong.
The Sun's mass is about 333,000 times Earth's mass and without it, Earth would be a ball of Ice. One fart in our direction from the Sun and we are all fried, with or without SUV's.

Human influences are now much larger than those variations in solar output - that's just a fact.

Your post is short on credible evidence, saying ''that's just a fact'' carries no weight here.
Man's activities can't compare, the Sun is a ball of fire, 333,000 times Earth's mass, and that is a fact.

It's a measured fact that the influence of anthropogenic greenhouse gas and aerosol increases is now much larger than the variations in solar output -
