Damaged Oceans Worsen Climate Change for Humans

Damaged Oceans Worsen Climate Change for Humans

The report notes that with any additional degree of warming, intense sea events that used to occur once per century will in certain regions once per year by the middle of the 21st century.

"The oceans and the icy parts of the world are in big trouble, and that means we're all in big trouble, too", said one of the report's lead authors, Michael Oppenheimer, professor of geosciences and worldwide affairs at Princeton University. The award winning projects are recognised for their innovative solutions that address climate change, and help drive progress on many other sustainable development goals like poverty alleviation, gender equality and economic opportunity.

Observed changes have impacted terrestrial and freshwater species and ecosystems in high mountain and polar regions through the appearance of land previously covered by ice, changes in snow cover, and thawing permafrost, and scientists have high confidence about this. According to the worldwide team of scientists, there are some island nations that won't remain worth living.

The IPCC report points to some potentially irreversible changes and growing threats to the Earth's oceans and shrinking cryosphere. "Taken together, these changes show that the world's ocean and cryosphere have been taking the heat for climate change for decades". "The consequences for nature and humanity are sweeping and severe".

Increased mean and extreme sea level, alongside ocean warming and acidification, are projected to exacerbate risks for human communities in low-lying coastal areas (high confidence).

650 billion tonnes of ice were lost from Greenland, Antarctica and the world's glaciers per year between 2006 and 2015.

Arctic sea ice is declining in every month of the year, and is getting thinner.

"There was really not much in this report that was surprising given the predictions that were made 15 years ago", Douglass says.

The report, which was researched by more than 100 authors from 36 countries and sources over 7,000 scientific publications, is the most comprehensive in the ambit of changes in the ocean and cryosphere - the Earth's frozen regions - to date.

"We outline a "no-regrets to-do list" of ocean-based climate actions that could be set in motion today", the authors of the study wrote.

But if greenhouse gas emissions continue to increase strongly, the sea-level rise could reach 60-110 cm by 2100. This is slightly less than the traditional 1 meter (39 inches) that scientists often use.

A new worldwide report has revealed the clearest information to date on the future of our planet's oceans and frozen regions, and the price civilisation will pay if there is not urgent action.

The IPCC scientists have increased their predictions of the future rise in sea levels as evidence mounts that the Antarctic ice sheet is becoming less stable and prone to breaking up.

Willis said people should be prepared for a rise in sea levels to be twice these IPCC projections.

The warming water has devastated coral reefs through bleaching and has led to oxygen depletion. "We hope they will inspire others as we look to tackle one of society's biggest challenges".

Outside scientists praised the work but were disturbed by it.

The objective calls for an acceleration of the global transition to renewable energy, sustainable infrastructure and cities; responsible resource management of oceans, forests and agriculture, adapting cities to the impacts of climate change, aligning public policy and financing to facilitate the net zero energy emissions strategy.
