Scientists Warn: Nine Climate Tipping Points Now ‘Active’ – Could Threaten the Existence of Human Civilization

More than half of the climate tipping points identified a decade ago are now “active,” a group of leading scientists have warned. This threatens the loss of the Amazon rainforest and the great ice sheets of Antarctica and Greenland, which are currently undergoing measurable and unprecedented changes much earlier than expected. “We must admit that…

‘Existential threat to civilization’: Scientists warn planetary tipping points make climate bets too dangerous

Citing an “existential threat to civilization,” a group of top climate scientists have put out a new paper warning that the latest evidence related to climate tipping points—when natural systems reach their breaking point and cascading feedback loops accelerate collapse—could mean such dynamics are “more likely than was thought” and could come sooner as well.…

Climate Crisis and Climate Change

The comedian George Carlin has a great bit where he gives examples of ‘soft language’ that softens the original meaning of words: senior citizens instead of old people, and the landfill instead of the dump.Another example of ‘soft language’ is climate change – a term that was manufactured by Frank Luntz (who has since reversed…

CO2-eating E Coli bacteria ‘metabolically rewired’ to tackle climate change

Bacteria which normally consume sugar have been genetically altered to make them capable of surviving through consumption of CO2. The microorganisms could be harnessed to help produce sustainable supplies of food and fuel, scientists claim.Researchers in Israel created over the course of several months an E Coli strain which, through genetic manipulation, consumes CO2 for…

Urban Heat Islands Mean Warming Will Be Worse in Cities

If you take a trip from rural Virginia into Washington, D.C., you may notice a change in atmosphere—literally. Scientists say the “urban heat island” effect, which can raise temperatures in cities by several degrees compared with their surroundings, could be a risk to human health as growing urban populations exacerbate the heating effects of climate…

Turns Out the Heart of Mars Is Cold as Ice

Climate Explained is a collaboration between The Conversation, Stuff and the New Zealand Science Media Centre to answer your questions about climate change.If you have a question you’d like an expert to answer, please send it to climate.change@stuff.co.nzIf tiny concentrations of carbon dioxide can hold enough heat to create a global warming impact on Earth,…
