How do we Know Human are Causing Climate Change?

Says the troll.....
Everyone's entitled to their own opinions. No one is entitled to their own facts.





 
In its Sixth Assessment Report, the Intergovernmental Panel on Climate Change, composed of scientific experts from countries all over the world, concluded that it is unequivocal that the increase of CO2, methane, and nitrous oxide in the atmosphere over the industrial era is the result of human activities and that human influence is the principal driver of many changes observed across the atmosphere, ocean, cryosphere and biosphere.

Where is that change at on the globe?
 
From your link, none of this has happened.

Observable evidence of rapid climate change includes:
  • Global temperature rise
  • Warming ocean
  • Shrinking ice sheets
  • Retreating glaciers
  • Decreased snow cover
  • Sea level rise
  • Declining arctic sea ice
  • Extreme weather events
  • Ocean acidification
 
From your link, none of this is evidence. Not one of the nine!!!!!!! hahahaahahahahahaahah

So what's the evidence?​

The research falls into nine independently studied, but physically related, lines of evidence:

  1. Simple chemistry – When we burn carbon-based materials, carbon dioxide (CO2) is emitted (research beginning in the 1900s).
  2. Basic accounting of what we burn, and therefore how much CO2 we emit (data collection beginning in the 1970s).
  3. Measuring CO2 and other greenhouse gases in the atmosphere and trapped in ice to find they are increasing, with levels higher than anything we've seen in nearly a million years (measurements beginning in the 1950s).
  4. Chemical analysis of the atmospheric CO2 that reveals the increase is coming from burning fossil fuels (research beginning in the 1950s).
  5. Basic physics that shows us that CO2 absorbs heat (research beginning in the 1820s).
  6. Monitoring climate conditions to find that the air, sea and land is warming, as we would expect with rising greenhouse gas emissions; as a response, ice is melting and sea level is rising (research beginning in the 1930s).
  7. Ruling out natural factors that can influence climate like the sun and ocean cycles (research beginning in the 1830s).
  8. Employing computer models to run experiments of natural versus human-influenced simulations of Earth (research beginning in the 1960s).
  9. Consensus among scientists who consider all previous lines of evidence and make their own conclusions (polling beginning in the 1990s).

So... did we not have our coffee this morning?
 
From your link, implies the temperature of the earth should be the same everywhere.

Greenhouse gases affect Earth’s energy balance and climate

The Sun serves as the primary energy source for Earth’s climate. Some of the incoming sunlight is reflected directly back into space, especially by bright surfaces such as ice and clouds, and the rest is absorbed by the surface and the atmosphere. Much of this absorbed solar energy is re-emitted as heat (longwave or infrared radiation). The atmosphere in turn absorbs and re-radiates heat, some of which escapes to space. Any disturbance to this balance of incoming and outgoing energy will affect the climate. For example, small changes in the output of energy from the Sun will affect this balance directly.

Well as I said in the post, that isn't evidence. None of the items listed is evidence of climate change. I'm still waiting.

Just because someone wrote Evidence, doesn't mean it is. Is there still ice in the poles?

Did sea levels actually rise? hahahahahhahaahah

How many inches of snow did they just get in California?

How about snow at Lake Meade?

I can go on and on. Now, point to where climate changed on earth.

Start defending your posts asswipe.

Sure, it was good and hot. Now back on topic, What's been observed?

What warming oceans? Where? why is there still ice in the arctic? let's start here.

jc456 Reminder #1: Just saying it doesn't make it so.

My articles have references to published studies. Yours, not so much. Well, actually NONE.

When i was a contractor working at the FDA building, one of the scientists there had been working on studying effects of the peanut for over 40 years. I asked him what hasnt been studied about the peanut, in which he responded, "As long as they keep paying me, i will continue to study the peanut". Will he find anything else about the peanut he hasnt found out for those 40 years. I doubt, it but he sure was someone absent minded for all those years. Pay some one to find a result, he will find that result even if there wasnt a result. Idiots like you allow this shit to happen. By the way, with the US no longer being energy sufficient, with OPEC cancelling 1,000,000 barrels of crude a day, energy prices will end up back over 4 dollars a gallon. You can thank Joe Biden voters for that shit....

From your link... Likely is not evidence. And partially? .04% partially? hahahahahahahaha That isn't science, and isn't within the vicinity of evidence. Nor does it prove there is any hot spot to which the hot spot is. Where is it? Post that link if you don't mind. I'm far too stupid to find that link.


It is likely that this trend is partially due to human activities, although many uncertainties remain, particularly relating to estimates of natural variability.
