If the folks at Guinness World Records kept tabs on climate change, they’d be taking note that the planet has hit a milestone: levels of heat-trapping carbon dioxide in the atmosphere have averaged more than 400 parts per million each day for the entire month of April. That’s the first time this has happened in at least 800,000 years — and maybe

Plants need carbon dioxide for nourishment and a certain amount of it in the atmosphere helps trap enough heat to keep the planet from freezing. So how can something be so important but also potentially dangerous? Easy. Just like our bodies, the climate system can become unbalanced if it gets too much of a good thing. There are all sorts of

Another month, another carbon dioxide record. This time the record extends beyond the rocky slopes of Mauna Loa, Hawaii, home to the most storied carbon dioxide record, and includes 39 other sites around the globe to paint a troubling picture of a greenhouse gas rise with no signs of slowing down. For the first time since record keeping began

The average global temperature fluctuates every year. However, when you look at a snapshot of the global temperature trend, it's on the rise - particularly since 1970. The main cause? Carbon dioxide and other greenhouse gas emissions from human activities. There are plenty of factors that influence temperatures in different regions across the
