United Nations Fails – High Seas Treaty Sinks

Two months ago the Sea Save Foundation delegation participated in the United Nation’s Ocean Conference – Sustainable Development Goal #14. Delegate after delegate took the podium and passionately expressed their nations’ support for the protection and the conservation of oceans.
Scientists are concerned that the failure to protect open oceans will spell disaster not only for marine species, island communities and fisheries but for the entire planet.

Climate Change, the effects of which we are seeing daily in news headlines, is largely buffered by oceans. Ocean decline will cause a domino-like effect on the climate of our planet.

The United Nations has tried to pass the High Oceans treaty four times before, and this fifth-time failure to reach consensus was unexpected by most and is ...

Google ‘airbrushes’ out emissions from flying, BBC reveals

The way Google calculates the climate impact of your flights has changed, the BBC has discovered. Flights now appear to have much less impact on the environment than before. That’s because the world’s biggest search engine has taken a key driver of global warming out of its online carbon flight calculator.

“Google has airbrushed a huge chunk of the aviation industry’s climate impacts from its pages” says Dr Doug Parr, chief scientist of Greenpeace.

With Google hosting nine out of every 10 online searches, this could have wide repercussions for people’s travel decisions. 

The company said it made the change following consultations with its “industry partners”.

It affects the carbon calculator embedded in the company’s “Google Flights” search tool.

Warnings, again, from the ends of the Earth

The East Antarctic Ice Sheet (EAIS), so-called “sleeping giant”, which holds the majority of glacier ice on Earth, is closer to being “awakened” than scientists have previously believed. In research published this week, a team of scientists analyzed how EAIS behaved during warm periods in Earth’s past to predict how it will fare as the world continues heating. Recent satellite images already show signs of thinning ice and melting. 

“A key lesson from the past is that the EAIS is highly sensitive to even relatively modest warming scenarios. It isn’t as stable and protected as we once thought,” said co-author Professor Nerilie Abram, from Australian National University’s Research School of Earth Sciences.

If the global average temperature remains well below 2C, then EAIS is p...

How Climate Change Affects Biodiversity in Marine Ecosystems

The endless impacts of climate change aren’t limited to one type of ecosystem. Although many reports about climate change focus on how it affects human lives, how does climate change affect the biodiversity of marine ecosystems? Here’s the latest news on climate change and marine life, explained.

According to a 2020 report by the National Oceanic and Atmospheric Administration (NOAA), over 90 percent of global warming in the past 50 years has been absorbed by the ocean. Oceans have a central role in the stabilization of Earth’s temperatures, so when they absorb more heat than necessary, the global imbalance becomes catastrophic...

Drastic Action Needed to Save Oceans, Experts Warn Ahead of UN Summit

Major stakeholders have called for drastic action to save the planet’s oceans ahead of the United Nations Ocean Conference in Lisbon. “Politicians must listen to scientists,” Nuria Baylina of the Lisbon Oceanarium says. “It is urgent to take measures” on activities, such as fishing and emissions, the Portuguese biologist added, saying “drastic action is necessary.”

More than 20 heads of state and government are expected to convene at the Ocean Conference (June 27 – July 1), where delegations from 193 countries will draw up an action plan to protect the seas.

The Lisbon agenda will reinforce commitments of the 2030 agenda for Sustainable Development, which include reducing marine pollution and expanding protected waters to 30%.

So far the international community ...

Climate change: Rich nations accused of ‘betrayal’ at Bonn talks

Climate talks in Bonn headed into their final day with rich nations accused of betraying the developing world. Poorer countries say that a promise they would be compensated for the damage done by richer countries’ emissions would be honoured this year. They believed that new money to pay for the impacts of climate change that they can’t adapt to would be set up.

But in the discussions in Bonn, they say the issue has been side-lined by the US and Europe. 

For many participants, a concept known as loss and damage has become the key issue in the global climate negotiations. 

Developing country participants say climate impacts on their countries are more severe than on the richer nations and they have less financial capacity to cope.

“We are already living with loss and dama...

Ningaloo Corals Are Ill-Equipped To Handle Future Climate Change

The relatively pristine coral populations of WA’s inshore Kimberley region are better equipped to survive ocean warming than the World Heritage-listed Ningaloo Marine Park, according to a new Curtin University study.

Despite previous research predicting coral species would move south to cooler waters to protect themselves, the new study — published in Molecular Ecology — has found this may not hold true on the West Coast of Australia.

The new study, which investigated coral population connectivity and adaptive capacity, has found corals growing in different reef systems in north-western Australia are genetically isolated from each other.

The findings were based on the genetic data of a reef-building coral, Acropora digitifera, sampled from five well-known reef systems...

Bonn climate conference: World is “cooked” if we carry on with coal, US says

The US envoy on climate change John Kerry has warned that the war in Ukraine must not be used as an excuse to prolong global reliance on coal. Speaking to the BBC, Mr Kerry criticised a number of large countries for not living up to the promises they made at the COP26 climate summit. Climate diplomats meet again today in Bonn amid new, energy security worries.

If countries extend their reliance on coal in response to the war, then “we are cooked,” Mr Kerry said.

The fragile unity shown in Glasgow last November is likely to be tested in Bonn as countries deal with the fallout from Russia’s invasion of Ukraine and the cost of living crisis.

Mr Kerry told the BBC that despite these drawbacks, “as a world we are still not moving fast enough,” to rein in the emissions of warming gase...

Climate change is making the ocean lose its memory

Memories shape who we are – and who we will become. Our past helps us figure out what to do in increasingly stressful or confusing situations, and the more experience we have the better equipped we are to make the next move.

But people and other living things aren’t the only things with memory. Oceans, in a way, remember too. Ocean memory, a relatively new term, has hit the headlines recently as new research out this month in Science has demonstrated how the ocean is “losing its memory.” How that loss, which occurs thanks to human caused climate change, will alter the future is still up in the air.

Here’s what you need to know about the concept, and what its loss could mean for the future of the oceans and the planet. 

What is ocean memory?

While ocean memory might ha...

Ocean Acidity and Temperature Highest Ever Recorded

According to a new study from the World Meteorological Organization (WMO), in 2021 our oceans reached their hottest and most acidic levels since we began recording them. The study, which was part a larger report released annually, looked at four main drivers of climate change: greenhouse gas concentrations, sea level rise, ocean temperatures, and ocean acidity. All hit record highs last year.

“Our climate is changing before our eyes,” WMO Secretary General Petteri Taalas said in a statement. “The heat trapped by human-induced greenhouse gases will warm the planet for many generations to come.”

The rapidly rising temperatures and greenhouse gasses are having a catastrophic effect on our oceans...
