The problem is that the vast majority of that border runs straight down the middle of 1,254 snaking miles of the Rio Grande River — and ever-worsening, climate change-fueled floods greatly complicate any plausible design.
And that’s on top of siting problems so significant Trump’s Interior Secretary Ryan Zinke actually seemed to suggest the wall would be built on Mexico’s side of the river when he told ranchers last week, “We’re not going to put it on our side and cede the river to Mexico.”
Extreme weather and climate change make both the siting and design challenges unimaginably greater.
One of the basic predictions of climate science, confirmed by observations, is that the hotter it gets, the more water evaporates into the air, resulting in much more water available for deluges. Worse, in many places, the climate actually changes — blocking patterns are created that cause storm fronts to stall — which can lead to truly epic deluges.
The National Oceanic and Atmospheric Administration (NOAA) reported that in some areas, the May 2015 deluge was “greater than a 1-in-1000 year event.” Extreme events are becoming much more common. As Craig Fugate, head of the U.S. Federal Emergency Management Agency (FEMA) under President Obama, said after the epic year of extreme weather in 2010, “The term ‘100-year event’ really lost its meaning this year.”
Complicating the siting issue even further is the fact that, as the AP has noted, “treaties with Mexico prevent either country from constructing within the river’s flood plain.”
Indeed, the 1970 “Treaty to Resolve Pending Boundary Differences and Maintain the Rio Grande and Colorado River as the International Boundary” states that the joint U.S.-Mexico International Boundary and Water Commission “must approve construction of works proposed in either country” along those rivers. It explicitly prohibits the construction of projects “which, in the judgment of the commission, may cause deflection or obstruction of the normal flow of the river or of its flood flows.”
Ignoring that restriction would require Trump to blow up nearly 170 years of treaties with Mexico.

No it wouldn't. There is no increase in sea level. CO2 does not increase temperature. CO2 increased from 280 ppm to 407 ppm with no effect. CO2 isn't some wonder gas.

Same question. So those floods in the Rio aren't happening? How about trying a bit harder before you declare something fake?

Floods have happened thru out time!
It's a damn shame when people link mother nature to politics!
stupid as Trump is

I really hope you don't believe this bull crap.

So how can I take an article seriously when the last sentence says "Ignoring that restriction would require Trump to blow up nearly 170 years of treaties with Mexico." even though the article references a 1970 treaty. What is the 170 year old treaty that's about be blown up?
This isn't factual news, it's an opinion piece by the founding editor of Climate Progress. That's hardly scientific.

Funny how most on the left actually believe engineers won't take things like a river flooding or shifting into account. Like the actual people tasked with this haven't learned anything from their forefathers that built things like the hover dam! I can see the narrative trying to be filled here. That Trump is a climate change denier and his wall will prove just how...

Then tell the left to stop tying them together via green taxes!
