The near-record temperatures are expected to last into this weekend, forecasters say. While it's not unprecedented to see high temperatures climb toward 90F on an April day, the length of such an April heatwave is rarely seen.
Kennedy predicts hot and dry conditions from the west will shift eastward later this week, allowing for a noticeable warm-up and shift towards spring-like conditions.
"If you reside in a cooler climate, hold off on planting your dahlias until late April or even May. In warmer regions, where frost bids its farewell earlier in the year, April presents an ideal opportunity to get those tubers into the ground."
Research shows that summertime conditions can lead to cognitive impairments, particularly in memory and concentration. Factors such as sleep disruption, heat, dehydration, and smoke exposure are significant contributors to these effects.
The tilt of the Earth's axis as it orbits around the sun causes seasons. Different parts of the world receive different amounts of sunlight depending on that angle. In the Northern Hemisphere, we experience winter from December to March, while the Southern Hemisphere soaks up the sun.
Animals' risk of becoming roadkill depends on several factors, including how many vehicles are on the road, how many animals are on the road, and how animals and human drivers behave, explains Tom Langen, a professor of biology at Clarkson University, who studies animal-vehicle collisions. DST can minimize these collisions, however.
Because we're homeotherms, we assume all mammals work the way we do. But in recent years, as improvements in technology allowed researchers to more easily track small animals and their metabolisms in the wild, we're starting to find a lot more weirdness.
An extraordinarily warm and mostly sunny January has left the snowpack across California's Sierra Nevada far smaller than usual - 59% of average for this time of year, state water officials announced Friday as they held the season's second snow survey. "We are now about halfway through the typically wettest part of the year," said Andy Reising, manager of snow surveys for the California Department of Water Resources.
