An article published in the magazine “Geophysical Research Letters” describes a research that offers a new estimate of the climate changes caused by the meteorite that about 66 million years ago led to the extinction of dinosaurs and a lot of other species of the time. According to a team of researchers the amount of sulfur released in the atmosphere was greater than the previous estimates with worse consequences. Part of the authors also participated in drills into the crater caused by the meteorite, which results are described in an article published in the magazine “GSA Today”.
