(Randall Irmis via AP)Plant-eating dinosaurs probably arrived in the Northern Hemisphere millions of years after their meat-eating cousins, a delay likely caused by climate change, a new study found. A new way of calculating the dates of dinosaur fossils found in Greenland shows that the plant eaters, called sauropodomorphs, were about 215 million years old, according to a study in Monday’s Proceedings of the National Academy of Sciences. So far, scientists haven’t found any example of the earliest plant-eating dinosaur family in the Northern Hemisphere that’s more than 215 million years old. The plant eaters “were late comers in the Northern Hemisphere,” said study lead author Dennis Kent, of Columbia University. That highlighted the migration time gap, said several outside experts both in dinosaurs and and ancient climate.

On January 1st, the sun was overhead for 10 hours 14 minutes and 9 seconds, which is 28 seconds longer than the the last day of 2020. The shorter nights have occurred since the winter solstice, when sunset occurred 2 minutes, 48 seconds longer on Dec 21, 2020. The sun is south of the equator during our winter sending longer amounts of daylight to the southern hemisphere. More sunlight reaches the southern hemisphere in winter. The sun will also spread out over more of the Northern Hemisphere, meaning our nights will continue to get shorter through June 20; culminating 3 hours, 52 minutes shorter by the summer solstice (Jun 20, 2020).

GENEVA – For all the recent talk of global warming, climate historians hunting for past temperature extremes have unearthed what the U.N. weather agency calls a new record low in the Northern Hemisphere — nearly -70 degrees Celsius (-93 F) was recorded almost three decades ago in Greenland. The World Meteorological Organizations publicly confirmed Wednesday the all-time cold reading for the hemisphere: -69.6 Celsius recorded on Dec. 22, 1991 at an automatic weather station in a remote site called Klinck, not far from the highest point on the Greenland Ice Sheet. “In the era of climate change, much attention focuses on new heat records," said WMO Secretary-General Professor Petteri Taalas in a statement. The new low was confirmed by so-called “climate detectives” working with the WMO's Archive of Weather and Climate Extremes in Geneva. The coldest temperature ever recorded on Earth was the -89.2 Celsius (-128.6 F) recorded in 1983 at the high-altitude Vostok weather station in Antarctica, WMO said.

Ordinarily, South Africa sees widespread influenza during the winter months, but this year almost none have been found something unprecedented. But theres no guarantee the Northern Hemisphere will avoid twin epidemics as its own flu season looms while the coronavirus still rages. This could be one of the worst seasons we've had from a public health perspective with COVID and flu coming together. The evidence: Ordinarily, South Africa sees widespread influenza during the Southern Hemisphere's winter months of May through August. In the United Kingdom, Prime Minister Boris Johnson likewise is urging widespread flu vaccination.

'Fall leaf' colors actually exist all year longNow, don't get too excited. Oh, fall leaf tourism brings in BIG MONEYIt's called "leaf peeping." Fall is only 'fall' to Americans, even though the term was coined in BritainWhat do you call the picking of ripe sweet potatoes, squash and pumpkins? Some time after, poets coined the phrase "the fall of leaves" -- shortened to "fall" in the 1600s. By the mid-1800s, the word "fall" had firmly rooted itself in America.
