Rising sea levels are one of the biggest challenges posed by climate change. Statistician and PhD student Fiona Turner has been studying the melting of Antarctica, to help researchers get to the core of predicting future sea level rises. It is important to predict the amount of sea level rise because it will affect coastal areas across the globe, some in more dramatic ways than others. The best way to estimate how much the sea level will increase in the future is to look backwards at how quickly it happened in the past with a warming climate. Direct measurements of climate phenomena only go back as far as the 17th century, so to reconstruct the possible shape of Antarctica before then, scientists use mathematical models to estimate the amount of ice stored on its surface.

Radiocarbon Dating - Reliable but Misunderstood
Research article 29 Jan Correspondence : Andreas Plach andreas. Surface melt is of high relevance due to its potential effect on ice core observations, e. An investigation of surface melt is particularly interesting for warm periods with high surface melt, such as the Eemian interglacial period. Furthermore, Eemian ice is the deepest and most compressed ice preserved on Greenland, resulting in our inability to identify melt layers visually. Therefore, simulating Eemian melt rates and associated melt layers is beneficial to improve the reconstruction of past surface elevation.

So I tried on these amazing new sailor pants that arrived at work today and I am absolutely in love with them! Rockabilly Girls!! This blog is meant as an appreciation of Rockabilly girls - plain and simple! Please feel free to submit photos of yourself but keep in mind that this is strictly Rockabilly!

In the past million years, the Earth experienced a major ice age about every , years. Scientists have several theories to explain this glacial cycle, but new research suggests the primary driving force is all in how the planet leans. The Earth's rotation axis is not perpendicular to the plane in which it orbits the Sun. It's offset by This tilt, or obliquity, explains why we have seasons and why places above the Arctic Circle have hour darkness in winter and constant sunlight in the summer.
