A Digital Journey for a Sustainable Future

The year was 2025. The world was on the brink of a climate catastrophe, and the need for urgent action had never been more pressing. Inspired by the book “I Ran the World,” a group of activists launched a groundbreaking campaign to mobilise millions of people around the world to demand immediate and decisive action on climate change.

The campaign, dubbed “Get2COP,” was centred around a revolutionary app that allowed users to create virtual journeys to the COP30 conference in Brazil. By tracking their steps, runs, or bike rides, participants could contribute to a collective effort to reach COP30 virtually from wherever they lived in the world.

Their purpose? To deliver a message to the policymakers and leaders of the world that something must be done – now!

The app was designed to...

The Parrotfish’s Coral Crusade

In the vibrant depths of the ocean, a tiny, brightly colored fish played a crucial role in maintaining the delicate balance of the underwater world. This was the parrotfish, a seemingly insignificant creature with a remarkable ability to save the planet.

Parrotfish were nature’s underwater gardeners. Their strong teeth, resembling a beak, allowed them to scrape algae and other parasites from the surface of coral reefs. As they nibbled away, they unwittingly helped to keep the reefs clean and healthy. But their contribution went far beyond simple maintenance.

Coral reefs were often compared to underwater cities, teeming with life. They provided shelter for countless marine species, from tiny shrimp to majestic sharks...

400-year record heat threat to Great Barrier Reef

A study of samples taken from inside the bodies of centuries-old coral has revealed the threat climate change now poses to the Great Barrier Reef. Researchers in Australia say temperatures in and around the vast coral reef over the past decade are the highest recorded in 400 years. Extreme heat has already caused five mass bleaching events in the past nine years alone. Writing in the journal Nature, external, the scientists behind the study say increased temperatures, driven by climate change, now pose an “existential threat” to this natural wonder of the world.

World’s oceans suffer from record-breaking year of heat

Fuelled by climate change, the world’s oceans have broken temperature records every single day over the past year, a BBC analysis finds. Nearly 50 days have smashed existing highs for the time of year by the largest margin in the satellite era. Planet-warming gases are mostly to blame, but the natural weather event El Niño has also helped warm the seas.

The super-heated oceans have hit marine life hard and driven a new wave of coral bleaching.

The analysis is based on data from the EU’s Copernicus Climate Service.

Copernicus also confirmed that last month was the warmest April on record in terms of global air temperatures, extending that sequence of month-specific records to 11 in a row.

For many decades, the world’s oceans have been the Earth’s ‘get-out-of-jail card’ when i...

Following Antarctic whales for climate change clues

Scientists aboard an inflatable use crossbows to study whales

Inside the bodies of humpback whales are clues about how climate change is transforming Antarctica. Our BBC science team crossed the Southern Ocean, with the researchers, on a mission to follow and study the giant whales of this remote, frozen wilderness. At 03:00 in the morning there is an almighty crash. Every drawer in our cabin is flung open and contents hurled against the wall. We hit a 12-metre wave.

I’m not a seafarer; this is alarming, but apparently not unusual on the Drake Passage – the stretch of the notoriously rough Southern Ocean we are on. We’re aboard a 200-passenger tourist ship, with a team of wildlife scientists, on our way to the Antarctic Peninsula.

Fossil Fuels Blamed for ‘Colossal Tragedy’

The world is not doing enough to protect coral reefs, the United Nations’ special envoy for the ocean said last week, in defence of the marine ecosystems that protect biodiversity, sustain underwater life, and produce some of the oxygen we breathe. In an interview with The Associated Press on the sidelines of an international ocean conference in Greece, Peter Thomson suggested that all significant coral reefs should be included in marine protected areas under what is known as the “30×30” initiative, a plan to designate 30% of the world’s land and ocean areas as protected areas by 2030.

Top reef scientists announced last week that coral reefs are experiencing global bleaching for the fourth time—and the second time in just 10 years—as a result of warming oceans amid human-...

Atlantic Ocean circulation nearing ‘devastating’ tipping point.

The circulation of the Atlantic Ocean is heading towards a tipping point that is “bad news for the climate system and humanity”, a study has found. The scientists behind the research said they were shocked at the forecast speed of collapse once the point is reached, although they said it was not yet possible to predict how soon that would happen. Using computer models and past data, the researchers developed an early warning indicator for the breakdown of the Atlantic meridional overturning circulation (Amoc), a vast system of ocean currents that is a key component in global climate regulation.

They found Amoc is already on track towards an abrupt shift, which has not happened for more than 10,000 years and would have dire implications for large parts of the world.

Amoc, which e...

First Marine Fish Declared Extinct Due to Humans

Java Stingarees are the first marine fish to be declared extinct as a result of human activity. This troubling news was released with the International Union for Conservation of Nature’s (IUCN) latest update of its Red List of Threatened Species last week, along with reports of escalating climate impacts on freshwater fishes presented at COP28. A shocking quarter of all known freshwater fish species are currently at risk of extinction, with 20 percent impacted directly by climate change.

“Freshwater fishes make up more than half of the world’s known fish species, an incomprehensible diversity given that freshwater ecosystems comprise only 1 percent of aquatic habitat,” says Kathy Hughes, Co-Chair of the IUCN SSC Freshwater Fish Specialist Group.

“These diverse species are integral ...

The Undermined Aspect of Climate Change

The world’s oceans, covering an expansive 70% of our planet’s surface, are a lifeline for humanity and a cornerstone of Earth’s health. They are not just vast bodies of water; they are dynamic systems that regulate our climate, provide livelihoods for millions, and are home to a diverse array of marine life. In contemporary times, these critical ecosystems are under siege. Human activities, ranging from pollution to overfishing, are posing serious threats to their health and sustainability.

The benefits of oceans for humanity is as important as its very existence. Oceans absorb about 30% of carbon dioxide produced by humans, buffering the impacts of global warming...
