President Trump’s trip to France for the country’s Bastille Day parade in July left a big impression. So big, in fact, that he wants to replicate the experience back home.
As Trump met Monday with French President Emmanuel Macron, the commander in chief gushed about seeing France’s military might on display in the streets of Paris during his visit. And he told reporters he is looking into the possibility of having a parade down the streets of Washington on Independence Day to show the United States’ “military strength.”
“I was your guest at Bastille Day, and it was one of the greatest parades I’ve ever seen,” Trump told Macron, who sat next to him. “It was two hours on the button, and it was military might and, I think, a tremendous thing for France and the spirit of France.”
“To a large extent because of what I witnessed, we may do something like that on July Fourth in Washington down Pennsylvania Avenue,” Trump said.

The comments prompted laughter from Macron and other officials sitting around them. The leaders were meeting in New York ahead of the United Nations General Assembly. But it wasn’t the first time Trump has talked about wanting a military parade in the streets of Washington.
Before the inauguration, Trump officials inquired with the Pentagon about having armored vehicles participate in his inauguration parade, according to documents obtained by HuffPost. And he told The Washington Post in January that he hoped that during his tenure, U.S. military might would be on display.
“Being a great president has to do with a lot of things, but one of them is being a great cheerleader for the country,” Trump said in the January interview. “And we’re going to show the people as we build up our military, we’re going to display our military.”
“That military may come marching down Pennsylvania Avenue. That military may be flying over New York City and Washington, D.C., for parades. I mean, we’re going to be showing our military,” he added.

Although Trump is deeply unpopular in France, he was invited for the 100th Bastille Day ceremony in Paris by Macron in an effort to strengthen the relationship between the two countries and their new leaders. The lengthy parade seemed to thrill the president, who has long held a fascination with military force.
On Monday, seated next to Macron, he boasted about the levels of U.S. military spending so far in his term. And he said his goal would be to “try to top” what France did.
“I think we’re looking forward to doing that,” Trump said. “I’m speaking with General Kelly and with all of the people involved, and we’ll see if we can do it this year,” he added, referring to Chief of Staff John F. Kelly.
The Pentagon did not immediately respond to requests for comment about plans to hold such a parade.

A group of prominent scientists on Monday created a potential whiplash moment for climate policy, suggesting that humanity could have considerably more time than previously thought to avoid a “dangerous” level of global warming.
The upward revision to the planet’s influential “carbon budget” was published by a number of researchers who have been deeply involved in studying the concept, making it all the more unexpected. But other outside researchers raised questions about the work, leaving it unclear whether the new analysis — which, if correct, would have very large implications — will stick.
In a study published in the journal Nature Geoscience, a team of 10 researchers, led by Richard Millar of the University of Oxford, recalculated the carbon budget for limiting the Earth’s warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) above temperatures seen in the late 19th century. It had been widely assumed that this stringent target would prove unachievable — but the new study would appear to give us much more time to get our act together if we want to stay below it.
“What this paper means is that keeping warming to 1.5 degrees C still remains a geophysical possibility, contrary to quite widespread belief,” Millar said in a news briefing. He conducted the research with scientists from Britain, Canada, New Zealand, Austria, Switzerland and Norway.

But the new calculation diverged so much from what had gone before that other experts were still trying to figure out what to make of it.
“When it’s such a substantial difference, you really need to sit back and ponder what that actually means,” Glen Peters, an expert on climate and emissions trajectories at the Center for International Climate Research in Oslo, said of the paper. He was not involved in the research.
“The implications are pretty profound,” Peters continued. “But because of that, you’re going to have some extra eyes really scrutinizing that this is a robust result.”
That may have already begun, with at least one prominent climate scientist confessing he had a hard time believing the result.
“It is very hard to see how we could still have a substantial CO2 emissions budget left for 1.5 °C, given we’re already at 1 °C, thermal inertia means we’ll catch up with some more warming even without increased radiative forcing, and any CO2 emissions reductions inevitably comes with reduced aerosol load as well, the latter reduction causing some further warming,” Stefan Rahmstorf of the Potsdam Institute for Climate Impact Research in Germany said by email.
Any substantial revision to the carbon budget would have major implications, changing our ideas of how rapidly countries will need to ratchet down their greenhouse gas emissions in coming years and, thus, the very workings of global climate policymaking.

Limiting the Earth’s warming to 1.5 degrees Celsius above preindustrial temperatures was the most ambitious goal cited in the 2015 Paris climate agreement. It is of particular importance to vulnerable developing nations and small island states, which fear that they could be submerged by rising seas unless warming remains this modest.
Discussion up until now, however, has largely focused on how to avoid the more lenient but still-quite-difficult target of 2 degrees Celsius (3.6 degrees Fahrenheit). That is both because 1.5 degrees C was widely viewed as infeasible and because considerably less research had focused on studying the achievability of the target.
In 2013, the United Nations’ Intergovernmental Panel on Climate Change (IPCC) calculated that humanity could emit about 1,000 more gigatons, or billion tons, of carbon dioxide from 2011 onward if it wanted a good chance of limiting warming to 2 degrees C — launching the highly influential concept of the “carbon budget.”
The allowable emissions or budget for 1.5 degrees C would, naturally, be lower. One 2015 study found they were 200 billion to 400 billion tons. And we currently emit about 41 billion tons per year, so every three years, more than 100 billion tons are gone.
No wonder a recent study put the chance of limiting warming to 1.5 degrees C at 1 percent. Peters said that according to the prior paradigm, we basically would have used up the carbon budget for 1.5 degrees Celsius by the year 2022.
That’s what makes the new result so surprising: It finds that we have more than 700 billion tons left to emit to keep warming within 1.5 degrees Celsius, with a two-thirds probability of success. “That’s about 20 years at present-day emissions,” Millar said at the news briefing.
“These remaining budgets are substantially greater than the budgets that might have been inferred from the” IPCC, he added.

The recalculation emerges, said study co-author Joeri Rogelj of the International Institute for Applied Systems Analysis in Austria, because warming has been somewhat less than forecast by climate models — and because emissions have been somewhat more than expected.
“The most complex Earth system models that provided input to [the IPCC] tend to slightly overestimate historical warming, and at the same time underestimate compatible historical CO2 emissions,” he said by email. “These two small discrepancies accumulate over time and lead to an slight underestimation of the remaining carbon budget. What we did in this study is to reset the uncertainties, starting from where we are today.”
Pierre Friedlingstein, another author of the study and a professor at the University of Exeter in the United Kingdom, added at the news briefing that “the models end up with a warming which is larger than the observed warming for the current emissions. … So, therefore, they derive a budget which is much lower.”
The new research, thus, seems to potentially empower a critique of climate science that has often been leveled by skeptics, doubters and “lukewarmers” who argue that warming is shaping up to be less than climate models have predicted.
But Rahmstorf, for one, finds this to be part of the problem. “They appear to have adjusted the budget upward based on the idea that there has been less observed warming than suggested by the climate models, but that is not actually true if you do the comparison properly,” he wrote, citing the need to measure the warming of the Arctic properly and account for the effect of aerosols.
In the meantime, the result could be a lot of confusion, says Oliver Geden, who leads the EU Divisoin for the German Institute for International and Security Affairs.
“First, it is quite unusual that scientists say that the state of the climate is better than expected, that a recalculation of the remaining carbon budget gives us more breathing room, not less,”
Geden said. “Second, it is far from clear that the authors’ method/results will form a new scientific consensus, given that some researchers are already voicing objections. A significant carbon budget recalculation should not come as a surprise, but for many policymakers it will.”
Rogelj said the study did not explicitly consider whether the carbon budget for 2 degrees Celsius would also be larger, but, nonetheless, it surely rises substantially, too, if the analysis is correct.
Nonetheless, even with the new revision, the latest research finds that keeping warming below 1.5 degrees C will be quite hard. “Even with the largest estimates of the remaining carbon budget, this path is extremely challenging, starting reductions immediately and then reducing emissions to zero over 40 years,” Millar said at the press event.
Overall, the dispute raises questions about how widely the carbon-budget concept has proliferated — and just how much we actually understand it.
“It goes to show, this carbon-budget approach is still much more, let’s say, immature scientifically than what we often assume,” Peters said.
