That would be disastrous for many coastal communities, plus seafood now accounts for approximately 17 percent of the world's animal-based protein. They fear the oceans, they believe it is risky, ' he told an audience at the European Research and Innovation Days in Brussels, Belgium on 25 September.

The 2015 Paris Agreement signed by all 195 countries aims at keeping the temperature rise to less than 2C, warning that even then there will still be serious consequences because of rising seas and extreme and unpredictable weather.

Karmenu Vella, European Commissioner for Environment, Fisheries and Maritime Affairs, said that defence of the oceans and inland waters is one of today's top challenges for society. It is the largest carbon sink, the richest source of biodiversity.

O'Shanassy said "Australia has so much to lose" if we continue polluting our atmosphere. There is no longer time for debate.

A grim new global science assessment concludes that climate change is making the world's oceans warm, rise, lose oxygen and get more acidic at an ever-faster pace, while melting even more ice and snow.

"The report provides a unified assessment of the state of our Earth system under the increasing influence of anthropogenic climate change, of humanity's response thus far and of the far-reaching changes that science projects for our global climate in the future", said a statement from the Science Advisory Group.

"Our researchers' observations and projections regarding changes in the ocean and cryosphere confirm what the report summarises: carbon dioxide emissions, which have continued to rise steadily around the globe, are producing concrete consequences for all life on Earth, including humankind".

Humans will not be the only ones affected by degraded ocean ecosystems and the rapidly changing climate.

Bob Kopp, a Rutgers sea level rise expert, pointed out that the new report also lays out that there is "deep uncertainty" among scientists about the stability of the planet's ice sheets. That melting is important because it helps determine how quickly and how high sea levels rise. This is projected to continue in the near future.

According to the report, "extreme sea level events" - like high storm surge from tropical storms and nor'easters - are expected to increase at such a rate that, by 2100, storms that were once expected to occur once every century will be expected to happen annually at most locations. 'Water is the lifeblood of the planet and the changes that are highlighted in this report have effects for everyone'.

"Coastal impacts are the most economically significant direct impacts of climate change on New Jersey", Kopp said.

'We may already be committed to changes we can not reverse, ' he said.

Compiled by more than 100 authors who crunched 7,000 academic papers, the study documents the implications of warming oceans, fast-melting ice sheets in Greenland and Antarctica and shrinking glaciers.

The amount of excess heat that oceans have absorbed from the climate system.

Many are relevant to Canada, where northern and coastal communities are already living with the reality of climate change in a world that is 1 degree Celsius warmer, on average, than it was during preindustrial times. And if low-lying coastal areas and islands don't adapt, they're likely to be at higher risk of flooding.

"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 global affairs at Princeton University.

'It is not a question about adaptation or mitigation. Though they may seem very distant to some people, in fact we all directly or indirectly depend on the functions provided by the ocean and cryosphere. "The need for immediate, transformative action is clear".
