A global analysis of over 300 marine species spanning more than 100 years, shows that mammals, plankton, fish, plants and seabirds have been changing in abundance as our climate warms. At the cool edge of species ranges marine life is…
Ships’ emissions create measurable regional change in clouds
A container ship leaves a trail of white clouds in its wake that can linger in the air for hours. This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small…
