I see. After asking for evidence, you simply reject the physical evidence, and call it "nonsense." Is that like when a small child puts their fingers in their ears and says "LA LA LA" in an attempt to avoid hearing something?<quoted text>
And no, I don't buy into any of that nonsense they knew what this or that was hundreds of thousands of years ago.
Some science is very difficult to understand. This is not. Ice samples from earlier eras are analyzed for their carbon dioxide content. Exactly what part of this process do you think is nonsense? The retrieving of ice cores from Antarctica? The chemical analysis used to reveal the amount of carbon dioxide in the samples?
I'm going to post a link that explains this process in simple terms. Simple enough that you could understand it, if you chose to. But I'm pretty certain that you care more about being faithful to your political views than trying to understand the truth about our changing world.
"An ice core is a core sample that is typically removed from an ice sheet, most commonly from the polar ice caps of Antarctica, Greenland or from high mountain glaciers elsewhere. As the ice forms from the incremental build up of annual layers of snow, lower layers are older than upper, and an ice core contains ice formed over a range of years. The properties of the ice and the recrystallized inclusions within the ice can then be used to reconstruct a climatic record over the age range of the core, normally through isotopic analysis. This enables the reconstruction of local temperature records and the history of atmospheric composition.
The length of the record depends on the depth of the ice core and varies from a few years up to 800 kyr (800,000 years) for the EPICA core. The time resolution (i.e. the shortest time period which can be accurately distinguished) depends on the amount of annual snowfall, and reduces with depth as the ice compacts under the weight of layers accumulating on top of it. Upper layers of ice in a core correspond to a single year or sometimes a single season. Deeper into the ice the layers thin and annual layers become indistinguishable.
An ice core from the right site can be used to reconstruct an uninterrupted and detailed climate record extending over hundreds of thousands of years, providing information on a wide variety of aspects of climate at each point in time. It is the simultaneity of these properties recorded in the ice that makes ice cores such a powerful tool in paleoclimate research."
