Showing results for "Climate Change" in Biology

For billions of years, microbes have produced and consumed greenhouse gases that regulate global temperature and in turn other aspects of our climate. The balance of these gases maintains Earth's habitability. Methane, a greenhouse gas produced only by microbes, may have kept Earth out of a deep freeze billions of years ago. Likewise, variations in carbon dioxide, another greenhouse gas released by microbes and other organisms, help to explain the comings and goings of ice ages over the last million years. Now we face a human-made climate crisis with drastic consequences.

A veritable tsunami of studies and assessment reports outlines a stark picture of humanity's detrimental impacts on our planet's life and environmental health. Climate change is at the heart of many of these impacts. We cannot continue to live in the same way; we're facing relentless population growth, paired with ever-expanding energy and resource consumption. Every day we dither exacerbates the issues we have to repair. What are our options, though?
