UN report on world’s oceans is damning: ‘We’re all in big trouble’

A damning new report from the United Nations says that the world’s oceans are undergoing drastic, accelerated change. And the risks associated with these changes to the climate are getting ever greater, threatening hundreds of millions of people and the global economy itself.

The report, issued by the United Nations’ Intergovernmental Panel on Climate Change (IPCC), highlights the changes that are happening as a result of increased emissions from greenhouse gases, including: sea levels rising by three feet by 2100; significantly fewer fish in the oceans; stronger hurricanes; and regular flooding in coastal cities such as New York.

“Global warming has already reached 1 [degrees Celsius] above the pre-industrial level, due to past and current greenhouse gas emissions,” a press release issued in conjunction with the report said. “There is overwhelming evidence that this is resulting in profound consequences for ecosystems and people. The ocean is warmer, more acidic and less productive. Melting glaciers and ice sheets are causing sea level rise, and coastal extreme events are becoming more severe.”

PLASTIC POLLUTION IN WORLDS’ OCEANS COULD HAVE $2.5 TRILLION IMPACT, STUDY SAYS

The report, which was worked on by more than 100 scientists from 36 countries around the world, was approved by the 195 IPCC member governments. Hoesung Lee, chair of the IPCC, said that all parts of the globe, from the highest mountains to the deepest parts of the ocean, are being affected in a faster manner.

“The open sea, the Arctic, the Antarctic and the high mountains may seem far away to many people,” Lee said in the press release. “But we depend on them and are influenced by them directly and indirectly in many ways – for weather and climate, for food and water, for energy, trade, transport, recreation and tourism, for health and wellbeing, for culture and identity.”

Six hundred seventy million people live in high mountain regions, 680 million people are in low-lying coastal zones, 4 million live “permanently” in the Arctic region and 65 million people live on small island developing states, according to the report.

“The oceans and the icy parts of the world are in big trouble and that means we’re all in big trouble too,” one of the report’s lead authors, Michael Oppenheimer, professor of geosciences and international affairs at Princeton University, told the Associated Press. “The changes are accelerating.”

The press release notes that “without major investments in adaptation,” rising flood risks are likely, some of which could cause “some island nations” to become uninhabitable “due to climate-related ocean and cryosphere change.”

The changes, which previous reports have said could shrink “virtually all” economies around the globe by 2100, will affect people, plants, food, societies, infrastructure, in addition to the global economy.

The oceans absorb more than 90 percent of the excess heat from carbon pollution in the air, as well as much of the carbon dioxide itself. The seas warm more slowly than the air but trap the heat longer with bigger side effects — and the report links these waters with Earth’s snow and ice, called the cryosphere, because their futures are interconnected.

“The world’s oceans and cryosphere have been taking the heat for climate change for decades. The consequences for nature and humanity are sweeping and severe,” said Ko Barrett, vice chair of the IPCC and a deputy assistant administrator for research at the U.S. National Oceanic and Atmospheric Administration, in the release.

The IPCC report adds to a previous report from the U.N. that some coastal cities and those in the Arctic region will have to adopt. The previous report, published on June 25 from the United Nations Human Rights Council, warned that a potential “climate apartheid” could fracture the global population, splitting the planet between the wealthy and the rest of the world who will be “left to suffer.”

The report also notes that some of the changes to the Earth’s climate from human-induced events can no longer be stopped, such as some rise in sea levels. The report found that seas are now rising at 3.66 millimeters per year, up from a previous estimate of 3 millimeters.

Global sea-levels have risen 3.2 inches since 1993, according to the National Oceanic and Atmospheric Administration.

Other findings from the report include:

  • The world’s oceans have already lost 1 percent to 3 percent of the oxygen in their upper levels since 1970. As warming continues, the oceans will lose more oxygen. 
  • From 2006 to 2015, the ice melting from Greenland, Antarctica and the world’s mountain glaciers has accelerated and is now losing 720 billion tons (653 billion metric tons) of ice a year.
  • Arctic June snow cover has shrunk more than half since 1967, down nearly 1 million square miles (2.5 million square kilometers).
  • Arctic sea ice in September, the annual minimum, is down almost 13 percent per decade since 1979. This year’s low, reported Monday, tied for the second-lowest on record. If carbon pollution continues unabated, by the end of the century there will be a 10 percent to 35 percent chance each year that sea ice will disappear in the Arctic in September.
  • Marine animals are likely to decrease 15 percent, and catches by fisheries, in general, are expected to decline 21 percent to 24 percent by the end of the century because of climate change.

MELTING PERMAFROST IN ARCTIC WILL HAVE $70 TRILLION IMPACT, NEW STUDY SAYS

The report is conservative in some of its projections, including the levels of ice lost in Greenland and Antarctica, NASA oceanographer Josh Willis, who was not part of the study, told the AP.

“We’re not done revising our sea level rise projections and we won’t be for a while,” Willis said, adding that a rise in sea levels of twice the IPCC projections is possible.

Despite the bleak nature of the report and it stating that some changes to the Earth’s climate can longer be stopped, all hope is not lost. It calls on governments around the world to act and take swift action in an effort to mitigate some of the devastating effects.

“If we reduce emissions sharply, consequences for people and their livelihoods will still be challenging, but potentially more manageable for those who are most vulnerable,” Lee said in the release. “We increase our ability to build resilience and there will be more benefits for sustainable development.”

“Cutting greenhouse gas emissions will limit impacts on ocean ecosystems that provide us with food, support our health and shape our cultures,” Hans-Otto Pörtner, co-chair of IPCC Working Group II, concurred. “Reducing other pressures such as pollution will further help marine life deal with changes in their environment while enabling a more resilient ocean.”

Take Action with our Children

Pay attention to our children. They are the next occupants.

Listen to our children: The kids do think creatively because they don’t believe in “impossible” yet. The know it CAN be and MUST be done. They are the next occupants.

YOU can act and help RIGHT NOW. September 20 – 27th is set to be a week of action. Many adults are joining in striking on Friday September 20th. Sign up if you can, or support your kids and anyone else you know who will participate.

Swedish teenager Greta Thunberg became famous this spring for launching a student movement to compel adults to take action on climate change. (More on her in “Climate News”) “Climate News”

Thunberg is not alone. Other young people can be equally convincing, according to a paper published May 6 in Nature Climate Change. The team of social scientists and ecologists from North Carolina State University who authored the report found that children can increase their parents’ level of concern about climate change because, unlike adults, their views on the issue do not generally reflect any entrenched political ideology.

Seven Point Outline for Saving the Planet – Reddit

Reddit generated a lot of discussion over the past two weeks on this topic in a thread that began with a frustrated user asking “How do we save this f***ing planet?” Anonymous user “m4ybe” posted a detailed, seven-point response that caught fire. Even though we are not necessarily in agreement with some priorities and details, the list at least has a battle plan of actions we individually and together can take to keep our planet alive.

  • Completely overhaul agriculture
  • Eliminate non-recyclable single-use packaging or product
  • Seriously address energy production
  • Close any waste loops
  • Utilize known and effective alternative building materials
  • Change protein choices, increase sustainable protein production
  • Subsidize and incentivize birth control

Links to brief details of listed items, followed by link to a longer discussion. The original full Reddit conversation is available even though the original comment seems to have been deleted. The solution discussion at “Good” contains that link.

Is it TOO LATE to survive the changes?

Surviving climate change or too late?

Can we work together to fix what is broken in our climate?

We only have a few years before our climate becomes unsurvivable, according to scientists and educators. Change is already evident all around the world. Are we close to the destruction of humanity? Can we keep our planet alive?

All experts believe we are in grave danger. Like the seven blind men and the elephant, they disagree about the shape and texture of the beast, yet all agree that it is big, strong and dangerous unless tamed.

Most questions arise on which CO2 measure is most meaningful, on how much is man-caused rather than determined by natural sources, and of course, whether the main culprit is the fossil fuel industry.

Question (1): How do we know if it is too late? When will we know we have gone too far?

Answer: We may be awfully close, as measured by annual rise in temperature and CO2 concentration.

An article by “EarthTalk” in a 2015 Scientific American issue.includes study results that point to 2042 is the tipping point based on the annual increase in CO2 concentration of 1.92 ppm. Greenpeace has said we only have until around 2020 to significantly cut back on greenhouse gas output around the world.

Question (2): Can We Still Avoid the Worst Impacts of Climate Change?

Answer: Maybe. The international movement 350.org is a good source for updates on how we are progressing and what we can do. The non-profit group, founded by writer and activist William McKibben and others, is dedicated to reducing atmospheric CO2 to 350 ppm, which they believe is attainable.

Research questions:

  • HOW can we help make a cut back on CO2 output?
  • HAVE we cut back since the 2015 study cited above?
