Wild boars and their unexpected role in global warming | Digital Trends Spanish

Wild boars could be contributing significantly to global warming. At least that is what a study conducted by researchers at the University of Queensland in Australia and the University of Canterbury in New Zealand determined. According to the research, by uprooting the carbon trapped in the soil, these mammals release about 4.9 million metric tons of carbon dioxide per year worldwide, which is equivalent to 1.1 million vehicles. The team in charge used population prediction models in conjunction with advanced mapping techniques to determine the climate damage caused by these animals across the planet.

Climate study confirms worst-case scenario | Digital Trends Spanish

Global warming has caused the worst-case scenario predicted by the Intergovernmental Panel on Climate Change (IPCC), according to a study published in the journal Nature Climate Change. Led by Tom Slater of the Center for Polar Observation and Modeling at the University of Leeds, the work determined that the sea has risen 1.8 centimeters since the 90's as a result of the melting of Antarctica and Greenland. "If these rates continue, the ice sheets are expected to raise sea levels by an additional 17 cm and expose 16 million people to annual coastal flooding by the end of the century," the study house said in a press release. Supported by satellite images, the investigations revealed that the thawing of Antarctica has raised the global sea level by 7.2 millimeters, while Greenland h...

The world map in case the water rises or falls 1,000 meters | Digital Trends Spanish

Recent studies suggest that sea levels will be more variable as the oceans warm due to increased greenhouse gas emissions. In this sense, what would happen if the water level rises or falls 1,000 meters? From the Spanish site of Sputnik, it is said that, in reality, it is difficult for the ocean to rise or fall 1,000 meters, since "such a volume of water simply cannot arise by itself or disappear from nowhere." Either way, share a couple of graphs from user BasedMap (Reddit), which show what the world map would look like in either case. What does Earth look like with 1000 meters of sea-level rise or drop? #ocean #sealevel - Vivid Maps (@VividMaps) August 20, 2020 For the scenario of a 1,000 meter descent from the...

Satellite images show the melting of Antarctica | Digital Trends Spanish

A loss of nearly 4,000 gigatons of ice has experienced Antarctica since 1994, according to experts at the University of California, San Diego. In the last 25 years, thaw has produced enough water to fill the Grand Canyon of the Colorado. Scientists at the Scripps Institution of Oceanography re-created the process in detail based on records from four European Space Agency (ESA) satellite missions, ice speed data from NASA and computer models from the US agency. "This is the most compelling evidence yet that long-term changes in the Southern Ocean are the reason for the ongoing Antarctic ice loss," said lead study author Susheel Adusumilli. The Scripps graduate student also commented that "it is incredible that we can use satellites that orbit about 805 kilometers (500 mi...
