We're running out of food: NASA calculates when the climate makes harvest impossible

A study shows when the harvest of important foods becomes scarce.

Washington DC - Our planet faces grave consequences in the face of climate change.

On November 1, 2021, NASA published alarming figures in this regard in the journal "Nature Food".

According to the study, agriculture is facing considerable damage.

Even global food security could be called into question.

What's behind NASA's dire prognoses?

And when could they arrive?

Food is getting scarce on earth: NASA calculates when climate change will affect crops

It's not a nice prognosis: Climate change will soon have a negative impact on the cultivation of vital foods. This should be most visible and noticeable in maize cultivation. The fact that, according to a recent NASA study, the effects of climate change could become visible on this grain of all things affects all of humanity immensely. From making popcorn to feeding cows and chickens - there is hardly any other grain that is used as widely as corn. In short: maize is one of the most important crops in the world. The study by NASA, which recently cultivated chillies on the ISS, is of concern in this regard *.

NASA was already using its computer technology for a wide variety of research subjects.

A few weeks ago, NASA was still working on a disturbing asteroid simulation *.

Now the space agency is addressing the effects of climate change.

However, there is no positive result this time either.

NASA, most recently still in search of life on Mars *, calculated the expected rise in temperature on Earth.

The NASA researchers did not lose sight of the changes in precipitation and the increasing concentration of greenhouse gases in the atmosphere.

Food yield could fall by a quarter: NASA fears "serious global effects"

The USA, China and Brazil currently deliver the largest corn yields.

The fact that the popular crop is also grown in many places in Central Asia, West Africa and Central America underscores its importance.

Quite a few regions are financially dependent on the maize harvest.

As the NASA predictions reveal, however, it could get too hot, especially in the tropics, to continue growing the crops.

NASA predicts that yield will decline by almost a quarter by 2030.

"We did not expect to see such a fundamental shift in the previous generation of climate and harvest models," said NASA scientists with regard to climate and harvest models from 2014. Therefore, the lead author of the NASA study appeals: "A 20% decrease compared to the current level of production could have serious effects worldwide."

NASA researchers have little hope “even in optimistic climate change scenarios”

NASA author Jägermeyr gives humankind little hope: "Even in optimistic scenarios of climate change, in which societies make ambitious efforts to limit the global rise in temperature, global agriculture is facing a new climate reality". A few weeks ago, NASA announced that the earth is threatened with more flooding because of our moon *. This development is also associated with climate change - and shows once again how important it is to fight global warming.

Nonetheless, not all crops are in danger of succumbing to climate change.

The study reports, among other things, that warmer environments are even advantageous for the cultivation of wheat.

As “space.com” reports, the yields could increase by around 17%.

But in view of the looming scale of climate change, this would certainly be the only ray of hope.
