Geology, not CO2, controlled monsoon intensity in Asia’s ancient past
For millions of years, shifting geologic plates — not carbon dioxide levels —held the most sway over the intensity of Asia’s seasonal winds and rains.
- Earth
Powerful storms may be causing offshore ‘stormquakes’
A perfect-storm mixture of hurricane, ocean and seafloor topography can create distinct seismic signals called “stormquakes.”
- Paleontology
Big dinosaurs kept cool thanks to blood vessel clusters in their heads
Giant dinosaurs evolved several strategies for cooling their blood and avoiding heatstroke.
- Climate
In a climate crisis, is geoengineering worth the risks?
Some scientists say the world needs to reconsider some human-made ideas to cool the climate as dire warnings about the looming crisis ramp up.
- Climate
Malin Pinsky seeks to explain how climate change alters ocean life
As global temperatures rise, Malin Pinsky’s research attempts to understand how marine ecosystems are changing and why.
- Climate
IPCC report warns of a bleak future for oceans and frozen regions under climate change
A new IPCC report offers dire warnings about how climate change is altering oceans, the polar regions and the high snowy mountains.
- Climate
Expanding ice slabs are increasing Greenland’s contribution to sea level rise
Since 2001, melting and refreezing have created vast ice layers near the surface that could drastically amp up meltwater runoff and sea level rise.
- Earth
How Kilauea’s lava fed a massive phytoplankton bloom
Kilauea’s heavy flow of lava into the ocean in 2018 added both food and heat to fuel a sudden bloom of ocean algae.
- Earth
Hurricane Dorian’s slow pace makes it dangerous and hard to predict
Hurricane Dorian is one of several recent hurricanes that moved extremely slowly. Whether that's due to climate change isn't yet clear.
- Earth
Ocean acidification could weaken diatoms’ glass houses
Ocean acidification may lead to smaller, lighter diatoms in seawater, which could also shrink how much carbon the tiny ocean algae can help sequester.
- Climate
Mercury levels in fish are rising despite reduced emissions
Climate change and overfishing can increase how much mercury accumulates in fish, counteracting efforts to reduce human-caused emissions.
- Climate
The Arctic is burning and Greenland is melting, thanks to record heat
A heat wave is melting Greenland’s ice and fueling blazes across the Arctic that are pumping record amounts of carbon dioxide into the air.
