Fossil leaves reveal: Warming 56 million years ago thinned forest canopies

  • One response
A study in Science developed a quantitative method to reconstruct the density of ancient forests and found that heat and dryness outweighed the effect of carbon dioxide “fertilization.” The findings illustrate why canopy expansion in some areas is not balancing

Same drought, different result: The timing of water shortages changes the flowering season

  • No comments
An experiment with five Mediterranean plant species showed that the same reduction in water had different effects when it occurred in autumn, winter or spring. The presence of neighboring species also changed flowering times.

Analysis of more than seven decades of climate data suggests a link between temperature changes in the Indian Ocean and high-pressure systems that prevent rain in the eastern Mediterranean. December conditions may provide a clue
Major Oak, the ancient oak associated with the Robin Hood legends, stands in Sherwood Forest in England

After about a thousand years: "Robin Hood's Tree" in Sherwood Forest is dead

  • No comments
After centuries in the heart of Sherwood Forest, Major Oak has stopped growing leaves. Experts explain how visitor damage to the soil, weakened roots, drought and heatwaves have overwhelmed the oak associated with Robin Hood legends
Controlled flushing of sediment in a water reservoir in China, as part of an effort to maintain the reservoir's storage capacity.

The world's reservoirs are filling up with mud and losing capacity at an alarming rate.

  • No comments
A study in Nature Sustainability found that reservoirs around the world are losing an average of 7.3% of their storage capacity each decade, largely due to sediment accumulation. Small reservoirs are particularly vulnerable.

  • One response
Recent research has shown that in the future there will be fewer rainy days in our region due to the climate crisis, but there will be more heavy rain events. How can this be explained using simple scientific principles?
