- 			 Climate ClimateMangrove forests on the Yucatan Peninsula store record amounts of carbonDense tangles of roots and natural water-filled sinkholes join forces to stockpile as much as 2,800 metric tons of carbon per hectare in the soil. 
- 			 Microbes MicrobesThese climate-friendly microbes recycle carbon without producing methaneA newly discovered group of single-celled archaea break down decaying plants without adding the greenhouse gas methane to the atmosphere. 
- 			 Climate ClimateClimate change may have changed the direction of the North Pole’s driftA mid-1990s shift in the movement of the pole was driven by glacial melt, in part caused by climate change, among other factors, a new study reports. By Sid Perkins

- 			 Environment EnvironmentThe world wasted nearly 1 billion metric tons of food in 2019A new United Nations global food waste report shows where waste can be reduced, which would decrease hunger and greenhouse gas emissions. 
- 			 Animals AnimalsA year after Australia’s wildfires, extinction threatens hundreds of speciesAs experts piece together a fuller picture of the scale of damage to wildlife, more than 500 species may need to be listed as endangered. 
- 			 Paleontology PaleontologyClimate change helped some dinosaurs migrate to GreenlandA drop in CO2 levels helped massive plant eaters called sauropodomorphs trek from South America to Greenland 214 million years ago, says a new study. 
- 			 Earth EarthA drop in CFC emissions puts the hole in the ozone layer back on track to closingAfter a recent bump in illicit CFC-11 pollution, emissions of the ozone-destroying chemical are back down to pre-2013 levels. 
- 			 Earth EarthThree things to know about the disastrous flood in IndiaThe flood, which killed at least 30 people, may have been caused by a collapsing glacier or a landslide, with climate change possibly playing a role.
