The figure I saw for earth becoming uninhabitable was 250 million years into the future (this assuming no AGW.)

Energy can be created or destroyed, it's called virtual energy (and virtual particles) that can flit into and out of existence over very short time scales, but in any conventional sense it can't be created or destroyed. I'm sure people are fully aware of this with regards to fossil fuels too, but they simply do not care.

Yes they were exterminated the same way the Passenger Pigeon was. Humans have done horrendous things through history both to each other and to our fellow animals. For some really stupid reasons like feathers in hats. The people doing this must have been really pissed off when the women's rights movement decided to oppose this barbaric behavior by using fake fathers. This primitive behavior wasn't isolated to the United States either, barbaric colonizers who came to New Zealand decided to murder flightless parrots who live there in the middle of the night while they were sleeping with large nets and hammered them to death. These birds mate for life and refused to leave their mates while this mass murder was occurring. This in addition to the feral pests (cats, rats, etc.) who also preyed upon the native wildlife. Those flightless parrots were thought to be extinct, but a small population of them were found on an island which was blissfully free of humans and they are now vigorously protected. Ugly nearly hairless apes (as in humans) have always been jealous of other creatures who are much more attractive than they are and have always wanted what they have. Those are the facts. In a bit of poetic justice, we have large flocks of parakeets here in New York. These are called Monk Parakeets. They are extremely smart and very social and huddle near electrical wires for warmth during the winter.

snow is still possible in April but it seems most cases are after snowy winters? This is an interesting test case since, although the winter didn't have much snow it was at least somewhat cold. Snow in April after less snowy winters were on the minor side-- for example April 1990, April 1997, April 2000, April 2006. All were less than 2 inches.

spring birds are highly active though and nest building already

They were off for January 2016 too. Do they use some sort of computerized mapping device to make these? Perhaps they could feed all the data into it (not leaving anything out) and let the computer use some sort of data smoothing curve to generate a best fit map?

54-55 at JFK, they always run out way ahead but it looks like a sea breeze might be coming in shortly.

There were no scientific instruments to measure it of course but comparative analyses can be done between eras using tree rings and arctic ice core samples and even observing sedimentary rocks to determine when the largest storms or other events in a given era occurred. There's a whole field called paleoclimatology that is based on this. Using paleoclimatology we have been able to determine a giant hurricane (Cat 4?) hit our area in PreColumbian times (somewhere between the 1200s and 1400s.) There is also evidence of a megatsunami possibly caused by a meteoroid strike (perhaps the same one that created Chesapeake Bay), it broke off into two pieces and one part hit down in the DelMarva and the other part hit near Toms River, the resulting megatsunami could have been over 50 feet high and left tell tale signs in the sedimentary bedrock of our near coastal waters.

I love them but that forum as a whole is like a clique. We talk in the CC forum or the main forum. They used to be more present in the sports forum-- they are missed there.

And in the middle, during the Mesozoic, when the dinosaurs roamed, there was a lot more oxygen in the atmosphere and that's why all creatures back then were HUGE. Back before the Cambrian before there was multicellular life the earth didn't have any oxygen, only CO2 and N2. We needed plants and blue green algae (not really algae) to convert some CO2 into O2 as O2 is highly reactive with rocks and without plants would be removed from the atmosphere very quickly.

crazy, so we had two 8 inch snowstorms that winter? that's like a historic season compared to now (and compared to back then too.)

it was mostly above freezing even during the storm (33-34) and it lasted 36 hours and it really started accumulating at night. a big surprise, I'm sure that storm wouldn't have been predicted with today's models either. Is there any way to run today's models on past storms to see how they would have done?

la nina or el nino? snowy decembers usually portend well for us either way (see 2002-03).

spring birds have been here for a few days and already pairing up and building nests.

the new england forum is a little anal retentive, although I find it interesting how they don't have as much conflict in north vs south, inland vs coast, even though they cover a much larger area.

https://thestarryeye.typepad.com/weather/2013/01/new-york-city-snowstorms-1979-2011-.html March 1, 1914- Rain in the morning changed to snow around lunchtime and by midnight 13.5" had accumulated (an additional inch fell after midnight on 3/2). It was a very heavy, wet snow with a high water content (2.65") until around 9 PM when Arctic air moved in. This was the century's first snowstorm of a foot or more, and the first since February 1899, when 16 inches piled up. This remains the longest period between snowstorms of 12 inches or more. So interesting the first footer of the 1900s didn't happen until 1914.

1990-91 was a much more interesting winter than this one and probably warmer too.... that February 26, 1991 snowstorm was my favorite between February 1983 and January 1996.

https://thestarryeye.typepad.com/weather/2013/02/today-in-new-york-weather-history-february-26.html 1991 (Tuesday) A surprise snowstorm dumped 8.9" of wet snow, the biggest accumulation in eight years (when 17.6" buried the City on Feb. 11-12, 1983). Because the temperature was just above freezing for much of the day, the snow didn't accumulate much on the streets or sidewalks. This was the winter's third snowfall of five inches or more. https://thestarryeye.typepad.com/weather/2013/01/new-york-city-snowstorms-1979-2011-.html Feb. 26, 1991 - A surprise snowstorm dumped 8.9" of wet snow, the biggest accumulation in eight years (since 17.6" buried the City in on Feb. 11-12, 1983 ).

For the cyclic snowfall people, this site details them well. https://thestarryeye.typepad.com/weather/2015/03/an-extraordinarily-snowy-21st-century.html 40 inches of snow is considered a hefty amount for a New York winter, a total that's about 50% above average. Over the years, winters with this much snow have occurred once every four years. This average, however, masks extended periods with and without snowy winters. For example, winters between 1873 and 1923 averaged snowfall of 40 inches or more once every three years, but then the 24-year period that followed (between 1924 and 1947) had just one snowy winter. More recently there was a 26-year period between 1968 and 1993 that also had just one. Most recently, New York found itself in the midst of an abundance of snowy winters, the most recent being the winter of 2017-18. Specifically, nine of the sixteen winters between 2003-2018 had 40 inches or more of snow, an unprecedented concentration (including four winters in a row). Of the five winters that didn't see this much, three were well below average (under 13") and the other two picked up an average amount of snow. (The three winters after 2018 have each had less than 40", but winter 2020-21 came close, with 38.6" measured.)

Lows: EWR: 8 (1990) NYC: 7 (1990) LGA: 9 (1990) JFK: 9 (1990) A wild cold spell, it would be in the 80s 2 weeks later Did we get any snow accumulations in any of the below storms? Also didn't we have a 36 hour snowstorm on this date in 1991? 1990 - Unseasonably cold weather followed in the wake of the winter storm in the northeastern U.S. Ten cities reported record low temperatures for the date, including Syracuse NY with a reading of 10 degrees below zero. Freezing temperatures in southeastern Virginia caused considerable damage to plants and fruit trees. The barometric pressure reading of 30.88 inches at Wilmington NC was February record for that location. (The National Weather Summary) (Storm Data) 2004 - A major snowstorm dumps up to 20 inches of snow in the Charlotte metropolitan area. Charlotte's third largest snowstorm on record accumulates 11.6 inches at the airport. a wild cold spell, it would be in the 80s 2 weeks later

was this the 36 hour snowstorm? it only snowed between Newark and Long Island, north south east west of there no snow....

I think we did have this a few weeks ago lol-- it looks VERY familiar....

Tony, looks like one last chance for a big storm (rain, mixed or snow) March 8-9 weekend?

I grew up near Coney Island (Sheepshead Bay) and I definitely noticed the similarities in the late 70s and early 80s.

1857 and before then in the 1780s We don't really need AI for this stuff......
