By drilling into the Antarctic Ice sheet and extracting core samples we are in effect going back in time. The physical properties of the ice and of material trapped in it can be used to reconstruct the climate over the age range of the core. The proportions of different oxygen and hydrogen isotopes provide information about ancient temperatures, … Read more Climate History – New Ice Core data available
Today we have 3 scientific papers all focused on the demise of Antarctic Ice sheets. The theme is loosely yesterday, today and tomorrow. Let’s dive right in. Nature: West Antarctic ice sheet and CO2greenhouse effect: a threat of disaster The abstract reads … If the global consumption of fossil fuels continues to grow at its … Read more Antarctic Ice Sheet Loss – 3 papers
The media has picked up some stories concerning Antarctica’s Thwaites Glacier. For example … Independent: Massive cavity opening in Antarctic glacier is ‘disturbing’ sign of climate change, says Nasa CNN: Gigantic hole two-thirds the size of Manhattan discovered in Antarctic glacier etc… What is the alpha source for these stories? Basically it is the following NASA JPL … Read more Giant Void under Antarctic Ice
By using satellite data over a period of four decades it becomes possible to work out how much ice is being lost in the Antarctic. So how much is being lost? The answer comes via a new study that has just been published in PNAS on 22nd January 2019. Let’s take a look to see … Read more How much Ice is being lost in the Antarctic?
A new study has been published in nature that reveals some very worrying data. Looking back to see what has actually happened in the past is a good way to work out what is coming as we warm the planet, and it is that data that reveals the degree of warming required to melt vast … Read more New Study: Moderate warming will lead to huge increases in Sea level
