The start of California's rainy season has been pushed back from November to December, extending the state's wildfire season by nearly a month. Climate scientists attribute the delay to changes in atmospheric circulation patterns, which bring more rain to neighboring states like Washington and Oregon.
A new study found that climate-driven increases in carbon capture lead to earlier leaf senescence in temperate trees. This challenges the long-held expectation that warmer temperatures would cause leaves to stay on trees longer and slow down climate change.
Researchers at ETH Zurich identified a self-regulating mechanism that limits the productive period of trees, leading to earlier leaf fall. Global warming previously expected to delay senescence, but photosynthesis in spring and summer actually accelerates it.
Researchers analyzed a massive dataset of seasonal events across the former Soviet Union and found that species' activities fail to keep up with their cues due to past evolution. Local adaptation patterns result in a massive imprint on nature's calendar, making geographic variation in seasonal timing more pronounced in spring and less ...
Pygmy owls' ability to overwinter is threatened by climate-driven rot of their stored food. The study found that warmer temperatures and increased rainfall lead to reduced food quality, affecting female owls' survival.
