On June 23, 1988, a sultry day in Washington, James Hansen told Congress and the world that global warming wasn’t approaching — it had already arrived. The testimony of the top NASA scientist, said Rice University historian Douglas Brinkley, was “the opening salvo of the age of climate change.”
Thirty years later, it’s clear that Hansen and other doomsayers were right. But the change has been so sweeping that it is easy to lose sight of effects large and small — some obvious, others less conspicuous.
Earth is noticeably hotter, the weather stormier and more extreme. Polar regions have lost billions of tons of ice; sea levels have been raised by trillions of gallons of water. Far more wildfires rage.
Over 30 years — the time period climate scientists often use in their studies in order to minimize natural weather variations — the world’s annual temperature has warmed nearly 1 degree (0.54 degrees Celsius), according to the National Oceanic and Atmospheric Administration. And the temperature in the United States has gone up even more — nearly 1.6 degrees.
“The biggest change over the last 30 years, which is most of my life, is that we’re no longer thinking just about the future,” said Kathie Dello, a climate scientist at Oregon State University in Corvallis. “Climate change is here, it’s now and it’s hitting us hard from all sides.”
Warming hasn’t been just global, it’s been all too local. According to an Associated Press statistical analysis of 30 years of weather, ice, fire, ocean, biological and other data, every single one of the 344 climate divisions in the Lower 48 states — NOAA groupings of counties with similar weather — has warmed significantly, as has each of 188 cities examined.
The effects have been felt in cities from Atlantic City, New Jersey, where the yearly average temperature rose 2.9 degrees in the past 30 years, to Yakima, Washington, where the thermometer jumped a tad more. In the middle, Des Moines, Iowa, warmed by 3.3 degrees since 1988.
South central Colorado, the climate division just outside Salida, has warmed 2.3 degrees on average since 1988, among the warmest divisions in the contiguous United States.
When she was a little girl 30 years ago, winery marketing chief Jessica Shook used to cross country ski from her Salida doorstep in winter. It was that cold and there was that much snow. Now, she has to drive about 50 miles for snow that’s not on mountain tops, she said.
“T-shirt weather in January, that never used to happen when I was a child,” Shook said. When Buel Mattix bought his heating and cooling system company 15 years ago in Salida, he had maybe four air conditioning jobs a year. Now he’s got a waiting list of 10 to 15 air conditioning jobs long and may not get to all of them.
And then there’s the effect on wildfires. Veteran Salida firefighter Mike Sugaski used to think a fire of 10,000 acres was big. Now he fights fires 10 times as large.
“You kind of keep saying ‘How can they get much worse?’ But they do,” said Sugaski, who was riding his mountain bike on what usually are ski trails in January this year.
In fact, wildfires in the United States now consume more than twice the acreage they did 30 years ago.
The statistics tracking climate change since 1988 are almost numbing. North America and Europe have warmed 1.89 degrees — more than any other continent. The Northern Hemisphere has warmed more than the Southern, the land faster than the ocean. Across the United States, temperature increases were most evident at night and in summer and fall. Heat rose at a higher rate in the North than the South.
Since 1988, daily heat records have been broken more than 2.3 million times at weather stations across the nation, half a million times more than cold records were broken.
Doreen Pollack fled Chicago cold for Phoenix more than two decades ago, but in the past 30 years nighttime summer heat has increased almost 3.3 degrees there. She said when the power goes out, it gets unbearable, adding: “Be careful what you ask for.”
The AP interviewed more than 50 scientists who confirmed the depth and spread of warming.
Clara Deser, climate analysis chief at the National Center for Atmospheric Research, said that when dealing with 30-year time periods in smaller regions than continents or the globe as a whole, it would be unwise to say all the warming is man-made. Her studies show that in some places in North America — though not most — natural weather variability could account for as much as half of local warming.
But when you look at the globe as a whole, especially since 1970, nearly all the warming is man-made, said Zeke Hausfather of the independent science group Berkeley Earth. Without extra carbon dioxide and other greenhouse gases, he said, the Earth would be slightly cooling from a weakening sun. Numerous scientific studies and government reports calculate that greenhouse gases in the big picture account for more than 90 percent of post-industrial Earth’s warming.
“It would take centuries to a millennium to accomplish that kind of change with natural causes. This, in that context, is a dizzying pace,” said Kim Cobb, a climate scientist at Georgia Tech in Atlanta.
Since the 1800s, scientists have demonstrated that certain gases in Earth’s atmosphere trap heat from the sun like a blanket. Human activities such as burning of coal, oil and gasoline are releasing more of those gases into the atmosphere, especially carbon dioxide. U.S. and international science reports say that more than 90 percent of the warming that has happened since 1950 is man-made.
Others cautioned that what might seem to be small increases in temperature should not be taken lightly.
“One or two degrees may not sound like much, but raising your thermostat by just that amount will make a noticeable effect on your comfort,” said Deke Arndt, NOAA’s climate monitoring chief in Asheville, North Carolina, which has warmed nearly 1.8 degrees in 30 years.
Arndt said average temperatures don’t tell the entire story: “It’s the extremes that these changes bring.”
The nation’s extreme weather — flood-inducing downpours, extended droughts, heat waves and bitter cold and snow — has doubled in 30 years, according to a federal index.
The Northeast’s extreme rainfall has more than doubled. Brockton, Massachusetts, had only one day with at least four inches of rain from 1957 to 1988, but a dozen of them in the 30 years since, according to NOAA records. Ellicott City, Maryland, just had its second thousand-year flood in little less than two years.
And the summer’s named Atlantic storms? On average, the first one now forms nearly a month earlier than it did in 1988, according to University of Miami hurricane researcher Brian McNoldy.
The 14 costliest hurricanes in American history, adjusted for inflation, have hit since 1988, reflecting both growing coastal development and a span that included the most intense Atlantic storms on record.
“The collective damage done by Atlantic hurricanes in 2017 was well more than half of the entire budget of our Department of Defense,” said MIT’s Kerry Emanuel.
Climate scientists point to the Arctic as the place where climate change is most noticeable with dramatic sea ice loss, a melting Greenland ice sheet, receding glaciers and thawing permafrost. The Arctic has warmed twice as fast as the rest of the world.
Alaska’s annual average temperature has warmed 2.4 degrees since 1988 and 5.4 degrees in the winter. Since 1988, Utqiagvik, Alaska, formerly known as Barrow, has warmed more than 6 degrees yearly and more than 9 degrees in winter.
“The temperature change is noticeable. Our ground is thawing,” said Mike Aamodt, 73, the city’s former acting mayor. He had to move his own cabins at least four times because of coastal erosion and thawing ground due to global warming. “We live the climate change.”
The amount of Arctic sea ice in September, when it shrinks the most, fell by nearly one third since 1988. It is disappearing 50 years faster than scientists predicted, said Michael Mann, a climate scientist at Pennsylvania State University.
“There is a new Arctic now because the Arctic ocean is now navigable” at times in the summer, said Mark Serreze, director of the National Snow and Ice Data Center.
The vast majority of glaciers around the world have shrunk. A NASA satellite that measures shifts in gravity calculated that Earth’s glaciers lost 279 billion tons of ice — nearly 67 trillion gallons of water — from 2002 to 2017. In 1986, the Begich Boggs visitor center at Alaska’s Chugach National Forest opened to highlight the Portage glacier. But the glacier keeps shrinking.
“You absolutely cannot see it from the visitor center and you haven’t in the last 15 or so years,” said climatologist Brian Brettschneider of the University of Alaska Fairbanks.
Ice sheets in Greenland and West Antarctica have also shriveled, melting about 455 billion tons of ice into water, according to the NASA satellite. That’s enough to cover the state of Georgia in water nearly 9 feet deep.
And it is enough — coupled with all the other melting ice — to raise the level of the seas. Overall, NASA satellites have shown three inches of sea level rise (75 millimeters) in just the past 25 years.
With more than 70 percent of the Earth covered by oceans, a 3-inch increase means about 6,500 cubic miles (27,150 cubic km) of extra water. That’s enough to cover the entire United States with water about 9 feet deep.
It’s a fitting metaphor for climate change, say scientists: We’re in deep, and getting deeper.
Besides affecting our moods and making us grumble more, the crazy weather will inevitably affect our food. We are not talking exotic sea creatures and rain strains of food flax, but chocolate, wine, honey and a few more, which may not be available for sale in the near future. Due to global warming and drought, the production of food is adversely affected as extreme weather events have already ravaged different regions of the world. Imagine a world where breakfasts would no longer be doused in maple syrup or a planet completely devoid of coffee. So, stock them up, sip a little longer and breathe in them before they leave you craving.
Chocolate: You think you can’t do without chocolates? I insist you to think again. Because according to the experts the vicious circle of drought has affected West Africa, which manufactures 70% of the world’s chocolate. And gradually, it will reduce and may lead to unavailability of cocoa in the next 20-30 years. It is also said that we consume chocolates faster than it is produced.
Peanuts: Nuts might drive you nuts.These ‘fairly fussy plants’ require stable and particular environment to grow. Too little rain, the pods don’t germinate. Too much sunshine, the shoots wither. The production has shrunk in the last six-seven years and will continue to do so. Some say that peanuts might be extinct by 2030, so if no peanuts, no peanut butter. Ouch! But if they don’t, then it will become a luxury item and then be ready to shell out more money for it.
Maple Syrup: Pancake emergency! As sugar maple tree responsible for syrup is stressed to the point of disappearing, because of the unpredictable weather conditions. The maple, like peanuts is dependent on precise climate conditions of mild days and freezing nights that our ever-changing climate can no longer offer.
Chickpeas: What would Lebanese cuisine be like without hummus? The chickpeas need 76 gallons of water for every ounce and since there is not enough water, the overall production of legumes is declined by 40% around the world in the last one decade and expected to go down even more in the future. So at this rate, you better eat hummus while you still can.
Honey: No more sweet treat? Honey bee colonies are vanishing at an alarming rate and biologists had warned us about the colony collapse disorder – bees abandoning their hives over a decade now. Plenty of reasons are listed like, parasites, electromagnetic radiation, pathogens, genetically modified crops and many more. Climate change has restricted the areas for them, because humble bee species do not have the ability to easily adapt these changes, which shows the ripple effect in the production of honey.
Avocados: Avocados and chickpeas are like brothers when it comes to their making. To make just one pound of avocado 72 gallons of water is required, and that’s about how much water is used in the four average American showers. It just so happens that more than 80% of avocados are grown in California, where there is a drought. So it might just exterminate before we could even think.
Coffee: Coffee lovers, alert! You got to find a new way to do away with your Monday blues, because your favourite relaxtant is on the path to extinction. It is anticipated that all types of coffee beans will be wiped off the face of the earth by 2080. The rising temperature ruins the plantation of the coffee beans. So, the next time, breathe in the aroma and sip on your morning coffee for a little longer.
Bananas: No more bodybuilding, because no more bananas. Yes, this popular five-a-day fruit intake is on the list of endangered food items. Since bananas rely on moderate weather to ripen and then consistent water to thrive, farmers are being forced to make heavy investments. And a fungal disease called ‘The Panama Tropical Race 4’ is also wiping out banana plantations across the globe.
Fish: No more glowing skin? At the pace we are going the oceans will ran out of the fish by 2048. Overfishing, trawling, pollution and climate change are to be blamed for the disappearance of many aquatic species. As the ocean becomes warmer, there is a change in the ideal habitat temperature required by the water animals. Therefore, leading to shortage of fish.
Wine Grapes: Will there be no more wine festivals? Because the major type of grape used for wine production is picked after the rain, and there is either uneven rainfall or no rain. But a glimmer of hope always exists. So, if wine growers begin to exploit the diversity of those other thousand wine grape varities in earnest, the industry could survive. After all, it’s all about adaptation.
