Climate Change Uproots Global Agriculture

Map of the world color coded by relative soil health

In much of the world, climate change is altering regional growing conditions and making them more unpredictable. Farmers are finding it harder to consistently grow enough food to meet increasing demand. Securing the world’s food supply for the future, experts assert, requires us to tally the good and the bad in the current […]

How did forelimb function change as vertebrates acquired limbs and moved onto land?

When tetrapods (four-limbed vertebrates) began to move from water to land roughly 390 million years ago it set in motion the rise of lizards, birds, mammals, and all land animals that exist today, including humans […]

Role of dams in reducing global flood exposure under climate change

A new collaborative study led by researchers at the National Institute for Environmental Studies, the University of Tokyo, and Michigan State University exposes the role of dams for mitigating flood risk under climate change. Flood is amongst the costliest natural disasters. Globally, flood risk is projected to increase in the future, driven […]

Climate change will alter the position of the Earth’s tropical rain belt

Credit: Pixabay/CC0 Public Domain Future climate change will cause a regionally uneven shifting of the tropical rain belt—a narrow band of heavy precipitation near the equator—according to researchers at the University of California, Irvine and other institutions. This development may threaten food security for billions of people. In a study published today in Nature Climate […]

Changing resilience of oceans to climate change — ScienceDaily

Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests. Scientists used geological samples to estimate ocean oxygen during a period of global warming 56 million years ago — and found “limited expansion” of seafloor anoxia (absence of oxygen). Global warming — both past and present — depletes ocean oxygen, […]
