How do we know humans cause climate change?

Anomalies observed are much more skewed to colder areas and to the winter seasons, which is more in line with a stronger greenhouse effect. If it was a “Sun issue” the opposite would be true, in that summers and the tropics would have huge anomalies relative to the rest of the world, due to those areas receiving direct sunlight.

This is a geothermal cycle that’s used as a sort of “thermostat”. Carbon from dead organisms build up on the ocean floor, which gets subducted into the earth’s mantle, and eventually it’s released as CO2. Venus and Mars have a broken thermostat from being geologically dead or dormant: Venus has too much carbon in the air, Mars has too much in the planet. This is a natural source of CO2 which can drive ice ages and interglacial periods.

However, much more CO2 is in the air than just what is predicted from volcanoes, which means there’s another source. That’s where the fossil fuels come in.

 

In a closed system, increasing the saturation of CO2 in the atmosphere will produce a greater warming effect--this is undeniable. But of course, we don't live in a closed system. We live in a system where dozens of factors play into the earth's climate.

So the question isn't really "is climate change real?" The real questions should be:

• are any of the supposed increases primarily due to human activity?
• how severe is the threat of increased temperatures over time?
• what measures are we willing to undertake in order to attempt to rectify it?

Here's my issue:

Greenhouse gases are just one element of the earth's total warmth.
CO2 is only one of several greenhouse gases ... and it's not even the biggest one.
Only *3%* of CO2 in the atmosphere is from human activity.
The United States only accounts for 15% of all CO2 production.
Cap-and-trade policies, at most, attempt to curb US CO2 production by 80%.

So in the end, we're talking about a fraction of a fraction of a fraction of a fraction of a fraction. We will absolutely hamstring our economy, we'll completely eliminate our ability to be energy independent, and even if the global average temperature stays stagnant for the next 100 years, we'll have zero way of knowing whether or not cap-and-trade had anything to do with it.

Everyone will see their electricity rates skyrocket--and those are words straight out of Barack Obama's mouth. Under cap-and-trade, no one will be hurt more than the poor.

Is man-made global warming real? That's debatable. What's not debatable is that every proposed economic "solution" is economic suicide, and probably wouldn't affect the climate one iota.

 

I mean, even if other factors contribute to climate change as well, it's pretty undeniable that humans play an effect, too. So... as far as our responsibilities are concerned, I'm not sure what the point if the question is.

 

We don't. its plausable that some of our polution may have some effect on the temperature but the Earths temperature has been fluxuating for throughout its entire history. I think that we need to stop polluting the environment for obvious reasons but I do believe this climate change crisis is political in nature and is being used to get people in developed nations to accept the globalist policies that are detrimental to their general wellbeing and national sovereignty. The people harping on global warming the most are the same people who are responsible for allowing the pollution to continue. The EPA is worthless as fuck. We have all the options in the world for clean energy but they refused to implement a single one.

 

There's nothing "undeniable" or "provable" so far. There's consensus, but that's just mob mentality and as ever unreliable as in Galileo's day. On our Earth, there's a thousand or even a million variables for our little delicate life forms that require such a narrow bandwidth of gravity, light, temperature, radiation, supporting plants, and so many other things... it's hard to comprehend. We're starting to learn some of the variables. But, coming to conclusions and claiming irrefutable truth from scant observed evidence, speaking in terms of geologic time, is only an exercise in theory and religion inasmuch as so many have a agenda-based conclusions.

We should take the best care we can of our resources, but not be afraid to use them and survive. Speaking of us as a world community. We should allow for progress and exploration and exercise all due caution.

 

leftist propaganda

 

Listen, there is little evidence that suggests earth is going through "global warming". At the current time, the earth is warming. The earth goes through warming and cooling periods, right now we are in a warming period. It really is that simple, but here we are.

Humans do affect the environment, but not in such a way that the media / al gore portray it to. We already have acts/laws protecting the environment. We dont need to be dumping millions upon millions of dollars that we don't have into the prevention of global warming. Partially bc global warming doesn't exist in the realm that people determine it to be.

There are a plethora of scientists that discredit global warming. If you ask a majority of people, they would call me crazy. They look at the news and go into an instant frenzy.

Global warming doesn't really make any practical sense. Greenhouse gases are there, but have little effect on the earth.

Is the earth warming?

Yes, not at an alarming rate that we really need to be concerened about.

Do we need to dump millions and millions of imaginary money into programs to prevent global warming?

Absolutely not, there's so many other important things to spend it on, military for example.

Is Al Gore an idiot?

Yes. But people dick-ride this man, as well as national media sources..

 

These same morons that want you to believe in global whining are the same morons that want you to believe that bruce jenner is now a woman.

 

Hahahahah I'm weak af. Hey man, he (or she rather lol) is the bravest human alive. Look it up on the news!! It's true bro!!!!

 

Strange, isn’t it? He/she gets to keep his/her medal from the Olympics in men’s, while also being on a Vanity Fair cover being the bravest woman ever.

Which one is it???

 

Anyway, whether global warming is real or not, we aren’t exactly kind to our surroundings. We’re on an isolated planet; this is the only earth we have. Once it’s used up, then what’s next? When the rivers are polluted to the point where fish die, when the land can’t sustain food and when the air’s too toxic to breathe, what’s next?

Nonetheless, rushing to less reliable forms of energy is also irresponsible and has grave economic consequences. The best we can do is conserve on an individual basis while simultaneously promoting more funding to research. Less reliance on fossil fuels and nonrenewable sources also have political benefits (I.e. less reliance on terrorism-funding states like the Gulf states, etc.)
