This is just the early beginning of improvements in air quality and improved health. We just need to hurry up the changeover about a dozen times faster. Researchers Link Electric Cars With Better Air Quality & Improved Health
2023-07-31 Lack Of Sea Ice In Antarctica Has Climate Scientists Worried
Quote “”This could be linked to natural weather patterns, but he says what’s not explainable is that the warm layer has been getting “considerably warmer” since the 1960s. Could the fact that humans have added the heat equivalent to 25 billion atomic bombs like the one dropped on Hiroshima in the past 50 years have
