Construction debris to help oceans absorb more carbon dioxide.

Due to the increase in carbon dioxide concentration in the atmosphere, the oceans are becoming more acidic, which has negative consequences for marine life whose livelihood is based on calcium carbonate.

A project is starting on the Spanish island of Gran Canaria to counteract ocean acidification — with construction debris.

Drying Lakebeds Are Releasing Massive Amounts of #Carbon, Study Finds
The #AralSea Has Been Drying Up For 60 Years. New Research Shows It's Also Releasing Massive Amounts of Carbon
The study estimates that between 1960 and 2022, the evaporating sea has released 204 megatons of #carbondioxide into the atmosphere, based on site surveys and core samples collected from across the dry lakebed.

#MangroveForests are healing after decades of human destruction

by Matt McGrath and Esme Stallard
June 4, 2026

"The world's coastal #mangrove forests, which protect millions of people from storms - and soak up vast amounts of planet-warming gases - are staging an unexpected comeback, scientists find.

"For decades these swampy trees had been declining rapidly as they were cleared for fish farms and housing.

"But a new study shows that since 2010 the world has been gaining more mangroves than it has been losing - driven by stronger #LegalProtections and increased #PublicAwareness of their importance, sparked by disasters such as the 2004 Indian Ocean tsunami.

"The researchers say the key factor though is the remarkable capacity of these forests to #regenerate naturally once humans stop chopping them down.

"Mangroves are one of the world's unsung #environmental heroes.

"Not only do they store up to five times more #CarbonDioxide than land-based forests, but their tangled roots can also slow down waves and protect coastal communities from #StormSurges and #tsunamis.

"These same roots provide a perfect nursery for many species of fish and other #MarineLife - protecting them from predators and providing ample food.

"These benefits, though, have come under serious threat over the past century as the rise of fish farming, agriculture and the expansion of coastal cities and towns have seen mangroves chopped down and rapidly removed.

"From the 1980s to 2010, over 12,000 sq km (4,600 sq miles) of mangroves were cleared or destroyed across #Asia, #Africa and the #Americas - an area the size of Jamaica.

"However, the new study shows a real reversal of that trend, particularly over the last decade. The total net losses - the forest lost and not replaced - since the 1980s have now been reduced to around 849 sq km (328 sq miles)."

World Falling Short on #Methane Pledge, #UN Report Finds
Four years ago, over 100 countries signed a pledge to cut global methane #emissions by 30 percent by 2030. The greenhouse gas is released by the burning of #fossilfuels, leaky #landfills and industrial #agriculture. It warms the planet up to 80 times more than #carbondioxide over two decades and is responsible for roughly a third of all #globalwarming.

#Greenland is getting greener. That could have huge consequences for the world

By Angela Dewan, CNN
Published February 13, 2024

"Warmer air temperatures have driven #IceLoss, which has in turn raised land temperatures. That has caused the melting of #permafrost, a frozen layer just beneath the Earth’s surface and found in much of the #Arctic, and that melt releases planet-warming #CarbonDioxide and #methane, contributing to more #GlobalWarming. #PermafrostMelt is also causing #LandInstability, which could impact infrastructure and buildings.

"'We have seen signs that the loss of ice is triggering other reactions which will result in further loss of ice and further ‘greening’ of Greenland, where shrinking ice exposes bare rock that is then colonized by tundra and eventually shrub,' one of the report’s authors, Jonathan Carrivick, said in a press release. 'At the same time, water released from the melting ice is moving sediment and silt, and that eventually forms wetlands and fenlands.'

"The loss of ice is creating what’s known as a #FeedbackLoop. Snow and ice typically reflect the sun’s energy back into space, preventing excessive heating in parts of the Earth. But as ice disappears, those areas absorb more solar energy, raising land surface temperatures, which can cause further melt and other negative impacts.

"#IceMelt also increases the amount of water in lakes, where water absorbs more heat than snow, which increases land surface temperatures.

"Greenland has been warming at twice the global mean rate since the 1970s, and the study’s authors warn that more extreme temperatures in the future are likely.

"Greenland is the world’s biggest island and is mostly covered by ice and #glaciers. Around 57,000 people live in the country, which is an autonomous country within the Kingdom of Denmark. Much of the population is #indigenous and many people there rely on natural #ecosystems for their survival.

"Michael Grimes, the report’s lead author, said that the flow of sediments and nutrients into coastal waters was particularly problematic for #IndigenousCommunities that rely on fishing, as well as for hunters on other parts of the island.

"'These changes are critical, particularly for the indigenous populations whose traditional subsistence hunting practices rely on the stability of these delicate #ecosystems,' he said.

"'Moreover, the loss of ice mass in Greenland is a substantial contributor to #GlobalSeaLevelRise, a trend that poses significant challenges both now and in the future.'"
