Are these 100 people killing the planet?
Controversial map names CEOs of 100 companies producing 71 percent of the world's greenhouse gas emissions.
- Just 100 companies produce 71 percent of the world's greenhouse gases.
- This map lists their names and locations, and their CEOs.
- The climate crisis may be too complex for these 100 people to solve, but naming and shaming them is a good start.
Climate change may bring acidic oceans full of jellyfish
One often-neglected result of climate change is ocean acidification. If this process continues, we may start to see fewer fish and more jellyfish.
- Since the beginning of the industrial era, humanity has been pumping out unprecedented levels of CO2 into the atmosphere.
- A significant portion of this CO2 is sucked back into the ocean, where it reacts with water to produce carbonic acid.
- Most species fair poorly in the newly acidic ocean. Jellyfish, however, seem to resist ocean acidification more than others.
How Tasmanian devils are evolving to fight back against extinction
Devil facial tumor disease, or DFTD, has cut the Tasmanian devil population by 90 percent. Now, some devils have evolved to resist the virulent cancer.
- Devil facial tumor disease, or DFTD, is a transmissible cancer that Tasmanian devils spread through bites.
- The cancer is highly infectious and lethal, and the Tasmanian devil population has dropped by 90 percent since it was first discovered.
- In the short time that we've known about the disease, however, the devils seem to be evolving new defenses that are helping some of them fight back and survive.
Study: Much of the surface ocean will shift in color by end of 21st century
Climate-driven changes in phytoplankton communities will intensify the blue and green regions of the world’s oceans.

Climate change is causing significant changes to phytoplankton in the world's oceans, and a new MIT study finds that over the coming decades these changes will affect the ocean's color, intensifying its blue regions and its green ones. Satellites should detect these changes in hue, providing early warning of wide-scale changes to marine ecosystems.
Dead – yes, dead – tardigrade found beneath Antarctica
