Scientists bid farewell to the first Icelandic glacier lost to climate change. If more melt, it can be disastrous


Scientists say they are bidding farewell to Okjökull, the first Icelandic glacier lost to climate change, in a funeral of sorts.

Researchers will gather Sunday in Borgarfjörður, Iceland, to memorialize Okjökull, known as Ok for short, after it lost its status as a glacier in 2014. The inscription, titled "A letter to the future," on the monument paints a bleak picture.

"Ok is the first Icelandic glacier to lose its status as a glacier. In the next 200 years, all our glaciers are expected to follow the same path. This monument is to acknowledge that we know what is happening and know what needs to be done. Only you know if we did it," the plaque reads in English and Icelandic.

From the ice sheet in Greenland to the towering glaciers in West Antarctica, Earth's enormous masses of ice are melting fast. And though sea levels have risen and fallen throughout history, scientists say it's never happened at a rate this fast.

If glaciers continue to melt at the current rapid rate, it will pose a number of hazards for the planet, geologists say. Here are some of the potential hazards:

From not having kids to battling anxiety: Climate change is shaping life choices and affecting mental health

For some, ignoring climate change is not an option. It’s real, and preventing global warming from getting worse is a driving force in their lives.

Revelle Mast wanted to be an architect when she was a kid. She changed course in high school, deciding to pursue mechanical engineering to address the threat of climate change. But, last year, she made another life decision: to go into politics.

“I realized about a year ago that was not feasible on the time scale that climate change is happening,” Mast said. “Nine months ago, I quit my engineering job and went full time into political work.”

As global warming – the gradual increase in temperature of the Earth's atmosphere –accelerates, people are grappling with the idea that disastrous conditions may appear as soon as 2040. The reality of this potentially existential crisis greatly influences the way some people, especially those who have dedicated their lives to stopping climate change, make life decisions – whether that’s going vegan, living in a certain part of the country or deciding against having children. It even affects their mental health.

Food will become scarcer, grocery prices will spike and crops will lose their nutritional value due to the climate crisis, according to a major report on land use from the United Nation's Intergovernmental Panel on Climate Change released Thursday.

The climate crisis will also change what kinds of crops farmers can grow. Some climates will become too hot for what farmers are growing now. Some climates will see more flooding, more snow, more moisture in the air, which will also limit what can be grown.

Change food production and stop abusing land, major climate report warns

"The window is closing rapidly to have lower emissions and to keep warming to less than 2 degrees.That is the key message of this report," said one of the report's authors, Pamela McElwee, an associate professor of human ecology in the School of Environmental and Biological Sciences at Rutgers University.

The report found that quantitatively food nutrition could also decline. Wheat grown at high carbon dioxide levels, for example, will offer 6-13% less protein, 4-7% less zinc and 5-8% less iron, according to experiments done with these plants.

"We are studying how this would translate into the food we eat and also in a range of different crops, we are seeing similar results," said one of the report's authors, Cynthia Rosenzweig, a senior research scientist at the NASA Goddard Institute for Space Studies, where she heads the Climate Impacts Group.

Given that extreme events like the summer's heat wave in Europe are increasing in magnitude and intensity, food systems are already showing some strain, she said.

Undernourishment has long been a concern of scientists who watch the climate crisis closely.

The planet is being consumed by humans

When you don't have enough to eat it reduces your ability to function physically. It can diminish your ability to think clearly. It puts you at a greater risk for chronic disease and death, studies show.

While still too many people don't have enough to eat, the world had been making progress in this area. In the 1990s, 1.01 billion people were thought not to have enough to eat. By 2015 it was 80.5 million, or about 11% of the global population, according to the US Department of Agriculture.

The climate crisis could reverse this progress.

Impossible Burgers are coming to 1,500 cafeterias this fall

A study published in May that looked at the production of the top 10 global crops -- barley, cassava, maize, oil palm, rapeseed, rice, sorghum, soybean, sugarcane and wheat -- found that because of the climate crisis, the world has already seen a reduction of 35 trillion calories every year. That equates to about 1% of food calories lost each year.

"That means you are removing food calories for about 50 million people, that's already happening," said study author Deepak Ray, a senior scientist with the Institute on the Environment's Global Landscapes Initiative with the University of Minnesota. "Maybe in the future we will see even more lost, unless we prepare for it and draw down the carbon emissions."

Ray said the climate crisis effects regions differently. Europe, Southern Africa, South Asia and Australia are feeling the most negative impact of food production due to the climate crisis so far. In the United States, Illinois has seen an 8% reduction of corn yield, but in states like Iowa and in the upper Midwest, there have been some gains in production due to climate change, Ray said.

To help save the planet, cut back to a hamburger and a half per week

High-income countries will likely be able to cope, but areas like Sub-Saharan Africa and parts of Asia and India will become even more vulnerable. The rural poor are the least able to adapt, studies find.
"It's a very tough problem and for many countries that are already not food secure, hunger could become a much much larger issue," Ray said.

Plant physiologist Lewis Ziska does agree. His work has contributed to the IPCC report. His past work with the US Department of Agriculture found that the rising CO2 levels have had a negative impact on the nutritional value of certain crops such as rice, and the climate crisis has reduced crop yield. It has also negatively impacted floral development, meaning that the pollinators, bees and butterflies, that rely on that pollen are put in jeopardy by the climate crisis.

The shipping industry must go carbon neutral to survive

"Bees play an essential part of agriculture, many aspects of the food chain," Ziska said.

He considers food one of the most important issues policy makers should look at in the wake of the climate crisis.

"Food is the greater leveler among people," Ziska said.

Imagine if you have a bunch of people in a room that don't like each other, he said -- if there is plenty of food in the room, they may look at each other suspiciously, but they will likely get along. If, however, you make them all stay in the room for an extended period of time and start to remove the food so there is not enough to go around, that's when relationships get strained.

"All the hatred and fear and anxiety comes out of having not enough to eat, that's why it is so important to adapt now and so important to look at critical issues like food security," Ziska said.

Scientists say farmers could grow their way out of the climate crisis

But he remains concerned about how the United States' political will to adapt. President Donald Trump has consistently confused much of the science around climate change, and proclaimed he would pull the United States out of the Paris Agreement.

Ziska had been working at the USDA on climate change for years alongside "very good people who are in the department still," but quit his job in protest.

"Research and adaptation plans are essential for survival," said Ziska, who is now with Columbia University, where he will continue his work.

Scientists, he said, need to keep pushing to advance ways the planet can adapt and continue reducing the climate crisis negative impact on food. He thinks "It is essentially where the corn silk meets the soil."

The water is so hot in Alaska it's killing large numbers of salmon


Alaska has been in the throes of an unprecedented heat wave this summer, and the heat stress is killing salmon in large numbers.

Scientists have observed die-offs of several varieties of Alaskan salmon, including sockeye, chum and pink salmon.

Stephanie Quinn-Davidson, director of the Yukon Inter-Tribal Fish Commission, told CNN she took a group of scientists on an expedition along Alaska's Koyokuk River at the end of July, after locals alerted her to salmon die-offs on the stream.

She and the other scientists counted 850 dead unspawned salmon on that expedition, although they estimated the total was likely four to 10 times larger.

They looked for signs of lesions, parasites and infections, but came up empty. Nearly all the salmon they found had "beautiful eggs still inside them," she said. Because the die-off coincided with the heat wave, they concluded that heat stress was the cause of the mass deaths.

Quinn-Davidson said she'd been working as a scientist for eight years and had "never heard of anything to this extent before."
"I'm not sure people expected how large a die-off we'd see on these rivers," she said.

Anchorage was 90 degrees on July 4. That's not a typo


Last month was the warmest June on record, with an average temperature of 60.5 degrees -- 5.3 above average, according to the National Weather Service Anchorage, whose records for this location date to 1954 (66 total Junes). June marks the 16th consecutive month in which average temperatures ranged above normal.

"All 30 days in June had above average temperatures," the service noted.
