China’s coasts threatened by rapidly rising sea levels

Comments Off on China’s coasts threatened by rapidly rising sea levels

Sea levels are creeping up as temperatures get hotter here on Earth , and China’s State Oceanic Administration just revealed worrying information about its threat to the country’s coasts. Sea levels in 2016 in China rose 1.3 inches in just one year, a trend that could have challenging consequences. NASA data cited by International Business Times shows sea levels are rising by 0.13 inches (3.2 millimeters (mm) to 0.14 inches (3.6 mm) every year at coasts, but the statistics are far worse in China according to their oceanic administration. Sea levels are rising swiftly in China due to climate change , El Niño, and La Niña, according to the agency. Not only did sea levels rise dramatically from 2015 to 2016, but 2016 sea levels were also 3.2 inches (82 mm) higher than the average level between 1993 and 2001. In a statement, the administration said, “Against the background of global climate change, China’s coastal air and sea temperatures have soared, coastal air pressure has fallen, and sea levels have also soared.” Related: Climate change will be the demise of US national parks 38 mm may not seem like much, so oceanographer Huang Gang of the Chinese Academy of Sciences’ Institute of Atmospheric Physics put that in perspective, telling the South China Morning Post, “A few millimeters rise may seem small, but if you think about how big the ocean is, the changes make a huge difference when sea water hits the ground. The adverse impacts could come earlier if sea levels rise faster.” The administration said vulnerable coastal areas should start preparing with infrastructure updates like repairing drains or constructing dams or dykes. They warned such actions must happen soon to avoid damage. According to International Business Times, there are two main factors in climate change-caused rising sea levels: warmer ocean surface temperatures, which causes waters to expand, and melting glaciers. According to Reuters , sea temperatures between 1980 and 2016 increased by around 0.21 degrees Celsius, or 32 degrees Fahrenheit, per decade.

Researchers discover evidence of supernovae on the sea floor

Comments Off on Researchers discover evidence of supernovae on the sea floor

After a long and dedicated search, scientists believe they have discovered trace elements from supernovae settled on the sea floor. Iron isotopes created from a supernova explosion 2.2 million years ago have found their way into fossilized bacteria taken from a sample of the sea bed floor – the only place they could still be found after all this time. Astrophysicist Shawn Bishop from the Technical University of Munich , Germany, published a new paper in the Proceedings of the National Academy of Sciences detailing his findings and following up on the hunch he has been following for several years. According to Gizmodo , he used accelerator mass spectrometry to analyze bacteria found in core samples from the ocean floor , counting each and every iron-60 isotope atom he found. Related: NASA captures shockwave of a massive supernova for the first time ever Iron-60, or 60Fe, is one of many elements produced by supernovae during an explosion. After being dispersed around space, these elements eventually settle onto planets. Because of 60Fe’s short half-life, none of it should still be around on Earth. However, traces have been found in fossilized bacteria thought to have picked up the crystals from the sea bed long ago. When the bacteria die, 60Fe remains preserved in the fossil record . Australian National University’s Anton Wallner also published a study  in Nature earlier this year, solidifying the case for supernovae depositing 60Fe on Earth. He and his team estimate the closest explosion occurred about 326 light years away. It is thought that either this event or Bishop’s findings are related to the onset of the Pleistocene, which triggered a period of global cooling. Via Gizmodo Images via Wikimedia , Wikipedia
