How Trees Can Save Us

How Trees Can Save Us | CIHEAM Press Review | Scoop.it

Since humanity arrived, we have cut down trees for timber, agriculture and development. Our impact is a matter of scale. When humanity was a mere 300 million in pre-medieval times, forest ecosystems remained intact. We are now over 7 billion, doing essentially the same thing we did thousands of years ago. What may have been sustainable then is now extirpating entire complex ecosystems, along with species we may never know existed. Deforestation releases a massive carbon sink into the atmosphere, driving global warming.

Taller plants on the tundra - Research Highlights - Nature Middle East

Taller plants on the tundra - Research Highlights - Nature Middle East | CIHEAM Press Review | Scoop.it

Understanding vegetation changes on the tundra could improve predictions on the impacts of climate change.
Plants in tundra ecosystems are getting taller, according to a study conducted by a large consortium of over one hundred scientists, including a researcher affiliated with Qatar University. The changes could lead to a warmer ecosystem and alter how carbon is stored in the soil. Tundra ecosystems, present in northern arctic and alpine regions, lack trees but have an abundance of shrubs, grasses and mosses.
