Climate change has had a dramatic impact on the world’s weather for years, scientists can only make predictions about how global climate will continue to change going forward; but in all scenarios the circumstances are quite dire. The Middle East and North Africa (MENA) will see some of the most severe effects of climate change, which will permanently alter the lives of millions of people in the region. In the MENA region, climate change is projected to result in extreme drought and temperatures which will lead to increased water scarcity, in what is already the most water poor region in …

Our oceans are intimately related to the climate of our planet. Paleoceanographic approaches aim to study oceans through geologic time to improve models of future climate. Radioisotopes provide us with chemical tracers that help us understand change through time. The uraniumseries decay chain contains thorium-230, a decay product of uranium-234. This isotope is useful to paleoceanographers in its disequilibrium to its parent isotope and in determining the flux of sediment falling to the ocean floor. In order to use 230Th to study oceans, we must be able to accurately measure the amount of thorium in sediment samples. Thorium is found …
