Climate change could affect human evolution. Here's how.
NBC "News" ^ | September 7, 2018 | by Scott Solomon

As climate change brings rising temperatures, droughts, shifting patterns of precipitation and longer growing seasons, plants and animals are evolving to keep pace.

Biologists have observed squirrels and salmon developing at an accelerated pace, causing them to reproduce at a younger age. Earlier summers have caused some flowers to bloom earlier in the year.

As the planet continues to warm, evolutionary changes are expected in other species as well - including Homo sapiens. Climate change will alter the internal workings of our bodies in subtle but significant ways and will likely cause a noticeable shift in our appearance.

A warmer climate means malaria, West Nile virus and other diseases long confined primarily to the tropics will spread into temperate zones.

Similarly, our digestive systems will evolve in response to shifts in food availability - where crops and livestock can be cultivated.

Changing diets will also trigger changes in our microbiomes - the bacteria and other microorganisms that live in our guts and help to keep us healthy.

While these changes will be of enormous interest to biologists, they will be largely invisible. But as we change on the inside, we’ll also be changing on the outside. Evidence suggests that a warming planet could melt away differences between human races — or population groups, as scientists more accurately call them.

The reason why climate change could reduce racial differences is that it will trigger massive migrations. In recent decades the world has become more urbanized, with people moving into large cities in coastal areas. But as polar ice melts and sea levels rise, large numbers of people will be forced to flee the coasts. And as droughts become more common and more severe, people living in more arid areas will have to move to places with more reliable sources of water.

cities are not more reliable sources of water.

...large numbers of people living in more arid areas will be shot at the far outskirts of places with more reliable sources of water.

Could change ? ? ? That's bold. How about: Has, Will, and Forever .

These peeps think we can "freeze" climate so that our current preferred conditions are permanent.

I'd rather go back to 2017....to wet in the east, too dry in west this year. Yeah...that's the ticket...let's dial up a 2017. Sheesh.

This is so obviously true. Just jet down to Florida and everyone's skin is appreciably more wrinkled. They don't walk as fast either.

Do these people ever stop to think about how much climate change humans have already been through?

Goy gee Wally, you would think they would be investigating what species will be lost when we slip back into an Ice Age. But what the heck, all the worlds a stage.

I noticed that too. Everywhere you look, very fat people in ugly shorts. Can't wait until global cooling makes them cover up again.

You have to know it’s coming - “Trangenderism can be traced to Climate Change”

Scientists have determined that seasonal disruptions have affected the hormonal make-up of males and females, rendering DNA and genomes susceptible to mental disturbances and gender dysphoria. ;);););)

Humans do not adapt to changing conditions, humans alter their immediate surroundings as desired—or migrate to eat someone else’s porridge.

The migration of Europeans and Asians to North America along with Africans thrown into the mix will have a greater effect on human evolution than any change in the climate.

The stirring of the various gene pools and resultant hybridization is perhaps the most important series of events in human history
