Marine Expert Statement Calling for a Pause to Deep-Sea Mining
Signed by 653 marine science & policy experts from over 44 countries
The deep sea is home to a significant proportion of Earth’s biodiversity, with most species yet to be discovered. The richness and diversity of organisms in the deep sea supports ecosystem processes necessary for the Earth’s natural systems to function. The deep ocean also constitutes more than 90% of the biosphere, and plays a key role in climate regulation, fisheries production, and elemental cycling. It is an integral part of the culture and well-being of local communities and the seafloor forms part of the common heritage of humankind. However, deep-sea ecosystems are currently under stress from a number of anthropogenic stressors including climate change, bottom trawling and pollution. Deep-sea mining would add to these stressors, resulting in the loss of biodiversity and ecosystem functioning that would be irreversible on multi-generational timescales.

What to Know About Seagrass, the Ocean’s Overlooked Powerhouse
When most people think of coastal ecosystems, they think of mighty mangrove forests and colorful coral reefs. But these ecosystems are only the tip of the iceberg — there’s more beneath the surface, specifically seagrass.
Seagrasses provide humans with countless goods and services — everything from food security to shoreline protection to clean water. They are found in almost every sea around the world, with more than 1 billion people living within 100 kilometers of seagrass meadows. Yet most people are unfamiliar with the many benefits these plants provide to humans and animals alike.
Here, we answer key questions about seagrasses: What are they, where are they and why are they important? Let’s dive in.

Space Tourism Poses a Significant ‘Risk to the Climate’
Rockets launched by billionaires Elon Musk and Richard Branson emit black carbon in the stratosphere, where it is 500 times worse for the climate than it is on Earth. Billionaire Jeff Bezos’ rockets burn liquid hydrogen and oxygen and pose a lesser climate threat.

Did you know that whales are climate heroes?
These ocean giants store planet-warming carbon in their bodies – 33 tons in fact! That’s equivalent to thousands of trees.
They also play an important role in the overall health of the marine environment by boosting phytoplankton – microscopic plants that produce more than half the world’s oxygen. Without whales, we won’t have a healthy ocean, let alone a healthy planet

6 Things to Know About Direct Air Capture
While efforts to reduce GHG emissions should always take priority, meeting climate goals will also require carbon dioxide removal (CDR) — systems that remove carbon directly from the air — likely at the billion-tonne scale by mid-century. Carbon removal is needed not only to balance out residual emissions that cannot be or are not eliminated by 2050, but also to reduce the high concentration of carbon dioxide in the air, which is triggering increasingly devastating climate change impacts.
