“Earth is warming, and we know why. Light is reflected and absorbed by clouds, air, oceans, ice and land. Greenhouse gases are released and adsorbed by organic and inorganic sources. Both exchanges depend on a variety of factors such as temperature, ocean acidity, the amount of vegetation and — yes — the burning of fossil fuels.
What’s less clear is what climate change means for our future. “It’s not like this is string theory,” said Timothy Palmer, professor of climate physics at the University of Oxford. “We know the equations.” But we don’t know how to solve them. The many factors that affect the climate interact with one another and give rise to interconnected feedback cycles. The mathematics is so complex, the only way scientists know to handle it is by feeding the problem into computers, which then approximately solve the equations.
The International Panel for Climate Change based its latest full report, in 2014, on predictions from about two dozen such computer models. These models were independently developed by institutions in multiple countries. While similar in methodology, the models arrive at somewhat different long-term predictions. They all agree that Earth will continue to warm, but disagree on how much and how quickly.”
“HUEHUETENANGO, Guatemala — When Lesly Cano Gómez was 15, she wrote out her plan to migrate to America.
“My dream is to go to the United States,” she wrote, followed by three discussion sections: “How Am I Going to Pay for It,” “Who’s Going to Take Me” and “Who’s Going to Meet Me When I Get to the United States.”
There were extensive family talks about the trip, which Cano Gómez would have undertaken with her cousin, Enilda, who is four years younger than her.
“There wasn’t anything here,” Cano Gómez explained. “That’s why I wanted to migrate.”
She knew that along the way she could be murdered or trafficked to a brothel, or else die of thirst in the desert. “But I felt I needed to go,” she added. “The people I went to school with had migrated, a ton of them.”
Yet today, four years later, Cano Gómez is still here in her village of Chichalum in the rugged Huehuetenango district. She now has a reason to stay — and therein lies a message for President Trump.”
David Lindsay: Bravo Saint Nicholas. Here are two comments I endorsed.

“Last year, Hurricane Florence ripped through North Carolina, damaging Camp Lejeune. Hurricane Michael tore through Tyndall Air Force Base in Florida, leaving airplane hangars that housed our fifth-generation aircraft shredded and largely roofless. At Offutt Air Force Base in Nebraska, floodwaters swamped more than one million square feet of buildings, forcing military personnel to scramble to save sensitive equipment and munitions. The total cost to repair just three bases? In the billions.
Climate change is already impacting the way the Pentagon operates — its training, equipment, supply chains, construction, maintenance, and deployments. More and more, accomplishing the mission depends on our ability to continue operations in the face of floods, drought, wildfires, and desertification. The changing climate has geopolitical implications, as well. It’s what the Pentagon calls a “threat multiplier,” exacerbating the dangers posed by everything from infectious diseases to terrorism. In the Arctic, for example, melting ice has made previously closed sea routes easier to navigate, creating greater chances for competition and conflict over access to these waters and natural resources. In Southeast Asia, rising seas are forcing thousands of people to migrate from their homes, increasing the risk of ethnic and political strife.
In short, climate change is real, it is worsening by the day, and it is undermining our military readiness. And instead of meeting this threat head-on, Washington is ignoring it — and making it worse.
We have the most capable military in the world. It’s also the single largestgovernment consumer of energy, and it’s dependent on fossil fuels. The Pentagon spends about $4 billion a year to power its bases at fixed locations and consumes tens of billions of barrels of fuel per year. An Arleigh-Burke class destroyer can consume 1,000 gallons of fuel in an hour while underway. It cost the Pentagon as much as $400 per gallon to transport the gas needed to keep bases operational at the height of the war in Afghanistan; in Iraq, convoys transporting oil and gas were vulnerable targets for insurgent attacks. And our non-combat bases often depend on a commercial power grid that can go down for any number of reasons: old infrastructure, extreme weather, cyber-attacks. When the power’s out, it costs the Pentagon real money — more than $179,000 each day.”
