Climate Change Threatens Water and Food Supply on Earth

Climate Change Threatens Water and Food Supply on Earth

Climate change is one of those issues that we cannot neglect nor procrastinate anymore. According to a new study published in Nature Climate Change, climate change will be the culprit for Earth’s tropical rain belt that will cover about two-thirds of the planet. Therefore, food security and environmental safety for billions of people will be threatened, resulting in higher temperatures and less water and food.

The bad news is brought by CBS News, and the world needs to figure out a way to prevent the disaster that seems impending.

The disaster is expected by 2100

The tropical rain belt is known as the Intertropical Convergence Zone (ITCZ), meaning an area that circles the planet where trade winds from the Southern and Northern hemispheres meet.

Antonios Mamalakis, the lead author of the study, declared:

Our work shows that climate change will cause the position of Earth’s tropical rain belt to move in opposite directions in two longitudinal sectors that cover almost two thirds of the globe, a process that will have cascading effects on water availability and food production around the world.

Mamalakis, together with his colleagues, analyzed computer simulations from 27 climate models. They looked especially at how the rain belt would behave if greenhouse gas emissions continue to rise until 2100.

Researcher James Randerson is also worried about Asia’s situation, where he’s expecting the atmosphere to heat up faster than in other parts of the globe. The culprits will be the glacier melting in the Himalayas, the reductions in aerosol emissions, as well as the loss of snow cover from northern areas brought by climate change.

Although most of us won’t be around in 2100, we should all still try to do our best to stop the scourge. We’re talking about the future of our children and grandchildren.
