The study, published in Scientific Reports, is the first to demonstrate how widespread the decline was and the scale at which population decline took place 8,000 to 6,000 years ago.

Since the Agricultural Revolution about 12,000 years ago, humans have been selectively breeding plants with desirable traits such as high grain yield and disease resistance. 

As the planet continues to warm, multi-day heat waves are projected to increase in frequency, length and intensity. 

Over the past several years, Stanford transformed its energy infrastructure by electrifying its heating system, replacing its gas-fired power plant with grid power, creating a unique system to recover heat, building massive tanks to store hot and cold water, and building a solar power plant.

The effects of climate change, including floods and extreme temperatures, have become more important push factors in migration than economic inequality or conflict, according to a global study.

In recent years, glaciers near the North and South poles, as well as in mountainous areas, have been shrinking due to the effect of global warming, becoming a significant contributor to the recent sea level rise.

Each summer, a climatic shift brings persistent wind and rain to much of Southeast Asia, in the form of a seasonal monsoon. 

The timing and extent of spring flooding in the southwestern James Bay region of northern Ontario is exacerbated by climate change and human-induced changes that have affected spring ice breakup and ice jams.

Although climate skeptics might find it hard to believe with this year’s endless snow and freezing temperatures, climate change is making warm, sunny early springs increasingly common. 

It’s a classic policy dispute: How much should the current generation invest in reducing carbon emissions for the benefit of future generations?
