As meteorologists warned Thursday that temperatures above 100°F are expected to impact two-thirds of the country this weekend, U.S. government scientists revealed that last month was the hottest June ever recorded — bolstering calls for radical global action on the climate emergency.


The revelation came in a new monthly climate report from the National Oceanic and Atmospheric Administration (NOAA). Scientists at the agency's National Centers for Environmental Information found that "the global land and ocean surface temperature departure from average for June 2019 was the highest for the month of June in the 140-year NOAA global temperature dataset record, which dates back to 1880."

Meteorologist Jeff Masters, co-founder of Weather Underground, explained that "the global heat in June is especially impressive and significant given that only a weak (and weakening) El Niño event was in place. As human-produced greenhouse gases continue to heat up our planet, most global heat records are set during El Niño periods, because the warm waters that spread upward and eastward across the surface of the tropical Pacific during El Niño transfer heat from the ocean to the atmosphere."

According to NOAA, "Regionally, South America, Europe, Africa, the Hawaiian region, and the Gulf of Mexico had their warmest June in the 110-year record." Central and Eastern Europe, North-Central Russia, northeastern Canada and southern parts of South America endured the most notable departures from average June temperatures.

And, as Masters noted, that high heat came with consequences:

Three billion-dollar weather-related disasters hit the Earth last month, according to the June 2019 Catastrophe Report from insurance broker Aon: a severe weather outbreak in Europe ($1.1 billion), flooding in China ($9+ billion, including losses up until July 16), and a drought in India ($1.75 billion). In addition, severe weather outbreaks in the U.S. in late May and mid-March accumulated more than $1 billion in losses by the end of June, bringing the 2019 tally of billion-dollar weather disasters to 14.

Five of the disasters documented by Aon were in the United States. NOAA, in the climate anomalies and events section of its report, noted that higher than average rainfall across the Mississippi and Ohio Valleys and East Coast contributed to destructive flooding in those areas. Experts warn that as human behaviors continue to warm the planet, extreme weather events will become more intense and common.

NOAA scientists found that January through June tied with 2017 for the second-highest average temperature ever recorded in that six-month period over the past 140 years. Though 2016 still remains the hottest first six months of the year on record, last month beat 2016's June temperature average by 0.04°F, with an average global temperature 1.71°F above the 20th century average.

Jonathan Erdman, a senior meteorologist at The Weather Channel, wrote Thursday that although the increases may seem small, "ultimately, what's most important is not whether a given month is a fraction of a degree warmer or colder; rather, it's the overall trend, which continues its upward climb since the late 1970s."

In response to NOAA's report, climate scientist Phil Duffy, president and executive director of Woods Hole Research Center, told Reuters that "action is urgently needed at the world, federal, state, and local levels to rapidly cut fossil fuel pollution and to protect and rebuild naturally stored carbon."

The NOAA report, as Erdman noted, echoes conclusions about June temperatures by researchers at NASA's Goddard Institute for Space Studies, the Japan Meteorological Agency and Europe's Copernicus Climate Change Service (C3S).

Reacting to the C3S report earlier this month, the environmental advocacy group 350.org declared, "We need to act like this is the climate emergency it is."

The findings about June come on the heels of new research from the Union of Concerned Scientists (UCS) that shows without urgent global action to curb planet-heating human activities, "the number of days per year when the heat index — or 'feels like' temperature — exceeds 100°F would more than double from historical levels to an average of 36 across the country by midcentury and increase four-fold to an average of 54 by late century."

The USC report warned that the global community must pursue ambitious climate action "if we wish to spare people in the United States and around the world the mortal dangers of extreme and relentless heat."

The rallying cry to build it again and to build it better than before is inspiring after a natural disaster, but it may not be the best course of action, according to new research published in the journal Science.

"Faced with global warming, rising sea levels, and the climate-related extremes they intensify, the question is no longer whether some communities will retreat—moving people and assets out of harm's way—but why, where, when, and how they will retreat," the study begins.

The researchers suggest that it is time to rethink retreat, which is often seen as a last resort and a sign of weakness. Instead, it should be seen as the smart option and an opportunity to build new communities.

"We propose a reconceptualization of retreat as a suite of adaptation options that are both strategic and managed," the paper states. "Strategy integrates retreat into long-term development goals and identifies why retreat should occur and, in doing so, influences where and when."

The billions of dollars spent to rebuild the Jersey Shore and to create dunes to protect from future storms after Superstorm Sandy in 2012 may be a waste if sea level rise inundates the entire coastline.

"There's a definite rhetoric of, 'We're going to build it back better. We're going to win. We're going to beat this. Something technological is going to come and it's going to save us,'" said A.R. Siders, an assistant professor with the disaster research center at the University of Delaware and lead author of the paper, to the New York Times. "It's like, let's step back and think for a minute. You're in a fight with the ocean. You're fighting to hold the ocean in place. Maybe that's not the battle we want to pick."

Rethinking retreat could make it a strategic, efficient, and equitable way to adapt to the climate crisis, the study says.

Dr. Siders pointed out that it has happened before. She noted that in the 1970s, the small town of Soldiers Grove, Wisconsin moved itself out of the flood plain after one too many floods. The community found and reoriented the business district to take advantage of highway traffic and powered it entirely with solar energy, as the New York Times reported.

That's an important lesson now that rising sea levels pose a catastrophic risk around the world. Nearly 75 percent of the world's cities are along shorelines. In the U.S. alone coastline communities make up nearly 40 percent of the population— more than 123 million people, which is why Siders and her research team are so forthright about the urgency and the complexities of their findings, according to Harvard Magazine.

Some of those complexities include, coordinating moves across city, state or even international lines; cultural and social considerations like the importance of burial grounds or ancestral lands; reparations for losses or damage to historic practices; long-term social and psychological consequences; financial incentives that often contradict environmental imperatives; and the critical importance of managing retreat in a way that protects vulnerable and poor populations and that doesn't exacerbate past injustices, as Harvard Magazine reported.

If communities could practice strategic retreats, the study says, doing so would not only reduce the need for people to choose among bad options, but also improve their circumstances.

"It's a lot to think about," said Siders to Harvard Magazine. "And there are going to be hard choices. It will hurt—I mean, we have to get from here to some new future state, and that transition is going to be hard.…But the longer we put off making these decisions, the worse it will get, and the harder the decisions will become."

To help the transition, the paper recommends improved access to climate-hazard maps so communities can make informed choices about risk. And, the maps need to be improved and updated regularly, the paper said as the New York Times reported.


"It's not that everywhere should retreat," said Dr. Siders to the New York Times. "It's that retreat should be an option. It should be a real viable option on the table that some places will need to use."
