the atmosphere aint made up by equal amounts of water vapor and CO2
It's like some people aren't reading the article.
No one has been ignoring the Sun. It's a complete strawman to suggest people have been

As well, you'll note that sunspots are at a cyclical low, as detailed in the article. This will cause a lower amount of heat. And yet, despite this, we've just experienced the hottest oceans in the last 100 years.
I think you and the journalist missed this: Sun activity is very low at the moment. The last time it was this low it was really cold. It isn't really cold right now. This is very alarming. That means that the current warm climate is actually very cold for the current conditions. That means once the sun activity picks up again it is going to be very very hot.
Sadly the article (in order to find evidence for Climate Change hype) gets this totally wrong: This means that the effect of CO2 is even higher! If it wasn't for the sun giving us a break right now, it would be even warmer!
It's not a strawman. Until recently it was all about man-made global warming and other inconvenient truths. I remember posts even here on this forum where people were insistent on global warming (a more accurate term is "climate change") being man-made, and that it was crazy and irresponsible to think otherwise due to all the evidence.
It's a recent thing that people are starting to accept other causes for warming, and that maybe it's not a dangerous warming trend that will drown us all but just a cycle the earth goes through all the time.
I remember as a kid needing at jackets on Halloween, but for the past few years even Halloween was warm enough that kids would be out with no jackets. Only at night did it get cool enough to need them.
Is it not that cold in other parts of the world?
Global warming is a myth (using the popular definition of global warming and not the literal definition). Climate change is not. Humans are not causing the earth to warm, and it's not some dangerous thing that will melt our ice caps, drown our coasts and create deserts. We may not be helping it, but we aren't causing it, just like we didn't cause it when it happened at other points in history, like the Renaissance.
It's like the old ozone layer fears of years ago. Remember when using hair spray caused the ozone layer to disappear?

To the best of my knowledge, and this is from a report this year, the water vapour changes due to CO2 changes effectively double the greenhouse effect of CO2. For every degree the CO2 will raise temperatures, new water vapour will also raise the temp a degree.Water and carbon dioxide absorb at different wavelengths. Not a fair comparison.
No, it's a strawman. We've known about cycles for decades now, and the scientists are always happy to find new cycles. If we can explain a portion of any change in temperature with a cycle, it's happily thrown into the model. Everyone knows it would be foolish to ignore El Ninos, sunspots, albedo, etc. when discussing temperature trends. I pointed out a public access graph from 2001 (over 4 years before the documentary by Gore) that discussed sunspots and its suspected effects.It's not a strawman.

No, the term 'climate change' is being used because it more accurately describes the local effects. The Earth is warming, in that it's retaining more heat. But that does not mean that each location will get warmer, because climate is more complex than that. Global warming is causing climate change. And it's climate change that is the problem.Global warming is a myth (using the popular definition of global warming and not the literal definition). Climate change is not. Humans are not causing the earth to warm, and it's not some dangerous thing that will melt our ice caps, drown our coasts and create deserts. We may not be helping it, but we aren't causing it, just like we didn't cause it when it happened at other points in history, like the Renaissance.
Let me stress that just because the earth is warming does not mean there's global warming, because I define global warming as the popular alarmist definition of man-made emissions and pollution causing it. That's what people around here think when they hear that term. It's also why the term climate change is being used more and more instead.
You mean the ozone that was rapidly disappearing, and then rapidly slowed its disappearance once we globally got off our butts to reduce CFCs? That ozone layer?It's like the old ozone layer fears of years ago. Remember when using hair spray caused the ozone layer to disappear?
Yes, and don't forget global dimming.I think you and the journalist missed this: Sun activity is very low at the moment. The last time it was this low it was really cold. It isn't really cold right now. This is very alarming. That means that the current warm climate is actually very cold for the current conditions. That means once the sun activity picks up again it is going to be very very hot.

August here in South Jersey was miserably hot with temperatures in the high 90's many days. Even now, in early Sept. it's still very warm.It isn't really cold right now? It was an unusually cold summer
I think its a good thing, locking up 2/3rds or 3/4ths of the world's freshwater in ice sheets does not make a better world
Sure it does. All that ice reflects sunlight back into space and moderates temperature.
Melting it will certainly hurt humans, society, and the economy. Because the fact that all that ice is turned into salt water just means that the oceans will be higher.
It has no positive effect, because it will not be available for humans to use.
It cannot be expected to fall as rain in useful places.
So, more floods, more coastal destruction, more violent and destructive storms, less water for agriculture and human use, that's what you'll get.
The oceans under most ice caps aren't arable land.
Reduced salinity could also be bad for some of the more sensitive sea creatures. Or, it might just not be enough to significantly increase evaporation.
The winds, rain shadows, etc., that make some areas not get enough rain while others get too much likely won't change much, so the extra rain is most likely where there is too much rain already.
Less water for agriculture =/= less rain. Agriculture works best with a slow steady water supply, not the flash floods induced by heavy rain. Snow is better for agriculture as the frozen water melts gradually throughout the year and keeps river levels fairly constant.
Ice ages are actually supposed to have had quite mild weather.
Cooler summers were balanced by warmer winters, with little precipitation due to limited evaporation.
(I'm actually somewhat skeptical about global warming, and tend to think that adapting to the new environment is a more reasonable course of action than trying to stop it. There are other environmental problems I see as much more important. I prefer taxes based on the externalities of population rather than caps.)
