Revisions are coming to the US and Mexico’s border wall, as a new study finds that temperatures have reversed.
A joint project by University of Minnesota and University of Arizona researchers found that the temperatures in the Rio Grande Valley and in other border areas have stayed within a range of 10 to 12 degrees Fahrenheit (4 to 5 degrees Celsius) over the past month, which is about halfway between their average and their average for the same period last year.
The researchers also found that border temperatures were similar in some areas during the warmer months, but remained below average.
They say that this “reverse reversal” could be attributed to the heat coming from the interior of the United States, which has not warmed enough to produce the “warm-water” effect.
The reverse reversal was not just seen in areas where temperatures are cooler, but also in areas of high rainfall.
“This is the first time in our research that the reverse reversal has occurred in a year, so this is a big step forward in understanding how the warming in the tropics is affecting the northern border,” said Dr. Scott Dinges, the study’s lead author and a U-M professor of environmental science and engineering.
“The research is encouraging, but it does not tell us what the consequences of this will be for our country.
This is just the first year of this process, and there are still a lot of questions to be answered.”
The researchers did not determine the cause of the reversal, but said the findings suggest that “more research is needed to determine if this phenomenon is specific to one of the border crossings or if it is just a more general phenomenon in which the temperature changes over time.”
The research was published Monday in the journal Science Advances.
The paper does not say whether the reversal is related to climate change or the growing number of migrants and asylum seekers crossing the border.
