Although measurements performed on the first ice cores, Camp Century and Byrd, largely focused on the isotopic composition of the ice as an indicator of climate change, the number of studied parameters has steadily increased encompassing numerous measurements performed on the entrapped air bubbles, on...

models and associated climate change response, in the supplementary discussions B and C). Rather, we seek to directly contrast the past with the future and model with data, all within the same model framework, in order to draw new insights into what the paleo record can and cannot tell us...
In other words, weather doesn't last very long. It unfolds over the course of days, hours or even minutes. Therefore, it's liable to change quickly — which is why so many of us yearn for constant updates. Whenever you ask if your hometown is "supposed to get any rain" on...
The recent temperature rise since 1870, measured directly, but poorly early on, added to the end of the GISP2 ice age cores, which become unreliable after 1850, is close to the peak of this current warming phase, already turning towards zero as its rate of rise diminishes.. The “hiatus”...

The alternation of ice and warm ages is connected to glacial/interglacial CO2 concentration changes of approximately 80-100 ppmv with significant fine structure during Termination I [Monnin et al., 2001]. Changes in the carbon isotopic signature of CO2 during that time are expected to add to our...
I thought about those two times when I had seen apple cores thrown over the wall. But suddenly, another apple core was thrown over with speed! Enough was enough. Someone could be really hurt by these cores. Did the student(s) not realize that people live across the wall? Or did they ...
Ice cores are tubes of ice taken from deep below the surface of the ice today. Scientists can analyse the bubbles in each layer to calculate how much carbon dioxide they contain. Rising sea levels also tell us that the climate is warming up and this isn’t just due to melting ice caps...
though--not for individual dates,but they can ten the average temperature of a given year by such proxy measurements as growth marks in corals,deposits in ocean and lake sediments,and cores drilled into glacial ice.They can even use drawings of glaciers as there were hundreds of years ago ...
