Sentences with phrase «of paleoclimate data»

Now note that the most recent IPCC results (Fourth Assessment Report) indicate, with high confidence, a 21st - century temp increase of 3.5 - 8 deg F. My reading of the paleoclimate data suggests that the last time GAT was 3.5 deg F warmer was roughly 4 million years ago (whereas modern humans came on the scene roughly 150,000 years ago).

Climate model studies and empirical analyses of paleoclimate data can provide estimates of the amplification of climate sensitivity caused by slow feedbacks, excluding the singular mechanisms that caused the hyperthermal events.

For all the talk about CO2, there is a surprising lack of paleoclimate data on that peskly gas, but what I have been able to find is interesting.

One approach to answer these important questions is the investigation of paleoclimate data like the ancient alkenones analyzed by van der Bilt and colleagues.

It may be that ice records are the only sources of paleoclimate data he knows about.

As a geologist, I can't help but wonder whether the huge influx of paleoclimate data represented by Vostok and similar ice cores might not drive us to a new consensus, much as new information about the sea floor revolutionized thinking about the movement of continents (and later «plates») on the surface of the dynamic earth.

Any small «upticks» or «downticks» in temperature that last less than several hundred years in our compilation of paleoclimate data are probably not robust, as stated in the paper.

It's unfortunate that Mark failed to realise, that there are now 36 separate studies that all find a hockey stick from reconstructions of paleoclimate data.

Among the communities targeted by the EarthCube program, some communities, including scientists using marine annually resolved proxy archives, have yet to establish a cyberinfrastructure with improved standards for storage and sharing of paleoclimate data and archive - specific metadata on the physical samples.

Successful modeling of paleoclimate data with the high temperatures of the late 1990s is essential if we are to make robust, definitive conclusions about past temperature amplitudes and variability.»

The rollercoaster mirrors the shape of a graph of paleoclimate data reconstructed by Shaun Marcott and several other scientists in a paper they published back in 2013.

It's not even true that this is the first time the IPCC report has made use of paleoclimate data; references to past climates can be found many places in the Third Assessment Report.

Climate model studies and empirical analyses of paleoclimate data can provide estimates of the amplification of climate sensitivity caused by slow feedbacks, excluding the singular mechanisms that caused the hyperthermal events.
