While studying the environment and climate of southwest British Columbia, trying to estimate how these aspects were like millions of years ago, the researchers identified new BC volcanoes they didn’t know about. By employing field analysis and radiometric dating, Alex Wilson from the University of British Columbia tried to estimate when the last eruption occurred in the area and how the British Columbia climate would change in the future.
“We want to understand how ice sheets have behaved in British Columbia in the past because we want to know how the glaciers in British Columbia grow and retreat in relation to the glaciers of the rest of the world,” said Alex Wilson, cited by The Canadian Press. “One reason that we are so worried about is that we don’t know what will happen [in the future as Earth’s climate changes]. But there are clues in the ancient history of the Earth. The climate has fluctuated in the past, many times in the past. It has been colder and warmer than it is now,” he added.
Researchers Identified BC Volcanoes They Didn’t Know About
According to Wilson, the so-called Garibaldi Volcanic Belt experienced both periods warmer than the climate of the region is today and times when ice layers were covering its volcanoes. He added that more than 100 volcanoes in southwest British Columbia erupted close or under the ice sheets throughout the past 2 million years.
“A lot of the glaciers are melting very rapidly in BC. They are retreating back, and those glaciers are exposing rock that we haven’t seen before. We have actually discovered a number of new volcanoes we didn’t know about,” Alex Wilson said. The researcher also added that now, he is trying to estimate how possible it is for the retreating glaciers to trigger an eruption of the BC volcanoes.
