Not reversible by humans, because humans have nothing to do with climate change.

In any case, why on earth would anyone want to reverse the effects? The CO2 spike is boosting plant growth and greening the planet. Warmer climate is better for food production, economic growth, and human development.
Look at the following images, then the follow the link, and tell me again, with a straight face, that humans have nothing to do with climate change.

Yes humans had everything to do with that graph, we invented the technology to measure it accurately only at the point where it starts going up.


And I'm still useing the word accurately very loosely. It's a guesstimate at best.

For some perspective, the proportion of CO2 in the atmosphere has increased slightly more than one ten thousandth since the time that we could accurately and directly measure it without deriving historical estimates from proxies and models.

They are not guessing the historic data. it's accurately determined with Ico Core Data to name just one.

How much CO2 got trapped in the ice is not the same thing as how much CO2 is in the air. It takes a lot of interpretation and modelling to get to that and it will flatten out the extremes and give a more avarerge figure. For all we know there could have always been spikes in the data like we see now.

Have a look at how its done instead of guessing:

Exactly like I said. What do you disagree with?
Their findings are not only determined by "how much CO2 is trapped in the Ice" as you suggest would be inaccurate. They employ a vast amount of test and analysis procedures which have been in use for a very long time and is in constant development. The Accuracy of the sum of their findings is not disputed by those qualified to do so but instead concurred by them. Here are some of the methods used to determine conditions.

Visual analysis
Isotopic analysis
Palaeoatmospheric sampling
Glaciochemistry
Radionuclides



The International Partnerships in Ice Core Sciences have plans in place for the following, much more we can learn and do from this.

  • Retrieve ice cores that reach back over 1.2 million years, in order to obtain multiple iterations of ice core record for the 40,000-year long climate cycles known to have operated at that time. Current cores reach back over 800,000 years, and show 100,000-year cycles.
  • Improve ice core chronologies, including connecting chronologies of multiple cores.
  • Identify additional proxies from ice cores, for example for sea ice, marine biological productivity, or forest fires.
  • Drill additional cores to provide high-resolution data for the last 2,000 years, to use as input for detailed climate modelling.
  • Identify an improved drilling fluid
  • Improve the ability to handle brittle ice, both while drilling and in transport and storage
  • Find a way to handle cores which have pressurised water at bedrock
  • Come up with a standardised lightweight drill capable of drilling both wet and dry holes, and able to reach depths of up to 1000 m.
  • Improve core handling to maximise the information that can be obtained from each core.

And everything of that equals to their way of interpreting the data. The complexity involved doesn't make it better or more "scientific", it actually creates more room for error.

They don't "interpret" they analyse and develop their findings with processes that have been thoroughly developed, tested and proven.

Same thing. You don't actually disagree with anything I said you just don't like my word choices.

Climate change, and warming. Its real

Did we cause it? Nobody can answer that because nobody has the data
