A new scientific study for climate change deniers to bash

April 4, 2012 by Citizen Carol

MSNBC reports that a scientific paper published in the peer-reviewed journal Nature on Wednesday concluded that during the end of the last Ice Age (12,000 years ago), global temperatures rose after carbon dioxide levels started to rise. This provides even more scientific evidence that there is a connection between warming temperatures and rising carbon dioxide.

For this study, which was funded by the National Science Foundation, researchers reconstructed temperature records from ice and soil cores at 79 sites around the world from around the same time period.

Earlier studies postulated that changes in Earth’s orbit may have triggered the warming trend by causing ice sheets to melt, but the new study suggests CO2 played a more important role.

I’d sure like to know who all these Climate Change Deniers are, that you speak of…

I’ve heard about this study, so let me get this straight. Some ice cores show CO2 rising before temperature, other ice cores show CO2 rising after temperature.

What this study reveals is there are grave questions regarding the validity of using ice cores to show a causal relationship between temp and C02. I think this demonstrates that there is no causal relationship, at least none can be reliably determined from ice cores. It shows that ice core data is unreliable.

I’ve never fully trusted ice cores for paleoclimate data and now this study demonstrates that they are not reliable, some other method must be found.

Thanks for the heads up.

The meat industry contributes more to global warming than all the automobiles(cars, suvs, trucks), trains, planes, boats, ships, and submarines in all of the world combined. Want a cleaner, healthier earth? Go vegan.
