There exists a theory that, long ago, the entire surface of the Earth was completely frozen.
Yes, there is a possibility that Planet Earth once looked like a giant snowball, drifting through the cosmos.
Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.
One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.
There is about a tonne of plastic for each person living in the world today -- that's 8300 million tonnes of plastic produced since 1950, most of which has become waste and ended up in landfills. Even worse, plastic production is increasing and half of all the plastic on Earth was created in the past 13 years. But you can reduce your own impact by cutting back your plastic consumption. Here are eight steps you could take.
There's no doubt that if we're going to stop or even slow down climate change, we have to get our collective crap together. But collective action starts with individual choices, and for all the data-driven decision makers out there, the path forward just got a bit more lucid. A new study in Environmental Research Letters has determined exactly which life choices reduce our carbon footprints the most.
Environmental issues often feel too massive for a single person to make any sort of difference -- and that's partially true. It will take a lot more than recycling. Still, there are plenty of small, realistic things you can change in your own life to do your part while the rest of the world catches up.
Climate change is definitely happening, but it's doing more than warming up the planet -- it's also affecting our well-being. A new report from the American Psychological Association explains how climate change is gradually taking a toll on our mental health.
It is becoming increasingly difficult for so-called climate deniers to maintain weather patterns aren't changing significantly to the detriment of the world. In 2016, extreme weather events flew thick and fast, with records being broken for heat temperatures and low sea ice extents. This infographic looks at some of the key extreme weather events of 2016 and the extent to which climate change can be blamed.
Why are conspiracy theories so prevalent, and how do they intersect with other phenomena such as climate change denial? Stephan Lewandowsky, chair of cognitive psychology at the University of Bristol, answered questions on the topic posed by the public on Reddit. The Conversation has curated the highlights.
