Only 1 to 2 percent of people in the world have red hair — and that number could continue to decrease due to climate change, scientists warn.
In Scotland, 13 percent of the population has red hair, which is believed to be an evolutionary response to the lack of sun. If temperatures continue to rise and the sun isn't blocked as often by clouds, the gene responsible for red hair could regress.
"We think red hair in Scotland, Ireland, and in the north of England is adaption to the climate," Dr. Alistair Moffat, managing director of ScotlandsDNA, tells Britain's The Independent. "I think the reason for light skin and red hair is that we do not get enough sun and we have to get all the vitamin D we can."
Moffat is worried that with climate change, the number of cloudy days will decrease. "If there was more sun, then yes, there would be fewer people carrying the gene," he said.
Another scientist who asked to remain anonymous agreed that the gene is slowly dying out, but suggested it will take several hundred years for that to happen. "Red hair and blue eyes are not adapted to a warm climate," the scientist said. "It is just a theory, but the recessive gene may likely be lost. The recessive gene could be in danger."

Sen. Marco Rubio (R-Fla.) maintained Friday that he'll support the Republican presidential nominee, even if that somebody happens to be Donald Trump, The Palm Beach Post reports.
In fact, Rubio might be more impressed with the billionaire business mogul than usual, saying his "performance has improved significantly" recently.
Republican presidential frontrunner Donald Trump was none too thrilled Saturday with the protesters who blocked his way into California's Republican convention the day before:
The "protesters" in California were thugs and criminals. Many are professionals. They should be dealt with strongly by law enforcement!

Leave it to Trump to make an off-color joke about the incident once he made it inside the hotel Friday.
Jimmy Fallon has been singing bits and pieces of Styx's "Too Much Time on My Hands" on The Tonight Show for days. On Friday, he and actor Paul Rudd took the obsession to its natural conclusion, creating a shot-by-shot remake of the '80s music video. The end result is sufficiently goofy. Take a look below.

Hundreds of activists stormed Iraq's parliament building Saturday in support of Shiite cleric Muqtada al-Sadr, who had accused Iraqi politicians of corruption, CBS News reports.
The demonstrators climbed over blast walls in Baghdad's Green Zone, which houses most of the country's ministries and foreign embassies, after parliament couldn't reach quorum to hold a session. The protesters broke furniture, chanted, and waved Iraqi flags.
San Francisco Police Chief Gregory Suhr released nine pages of racist and homophobic text messages sent between officers Friday and ordered all officers to undergo anti-bias training, The New York Times reports.
"We have nothing to hide," Suhr said of his 2,000-member force. "These are the actions of a few."
The messages, which disparaged blacks, Latinos, South Asians, and LGBT people, were found as part of an investigation into a rape charge against one of the officers.
