[_ Old Earth _] So how's the climate going?

I Agree. But Governments that say a "mess" should be cleaned up that isn't really a mess, should be cleaned up also,Right?

It comes down to evidence. If we see someone dumping something into the environment, that evidence shows to be harmful, then they need to clean it up.

Easy enough.

Show us the evidence that they've stopped the leak.. better yet tell us that if we just smile radiation won't harm us like one of they're Japanese officials told his people..
 
An higher and higher and higher....

Revelation 16:8 And the fourth angel poured out his vial upon the sun; and power was given unto him to scorch men with fire.

9 And men were scorched with great heat, and blasphemed the name of God, which hath power over these plagues: and they repented not to give him glory.

Higher and higher. Another record hot year this year. The disturbing part is that it's happening faster than predicted by scientists.

Yes, a unprecedented hot dry summer. Now, unfortunately, they are calling for a very cold winter with colder than normal temperatures and higher than normal snow falls. Just like when I was a boy... can't wait...not.

Extremely cold winters have less snow, as a rule. If you thought about it, I'm sure you could figure out why.

As first glance, asking whether global warming results in more snow may seem like a silly question because obviously, if it gets warm enough, there is no snow. Consequently, deniers of climate change have used recent snow dumps to cast doubt on a warming climate from human influences. Yet they could not be more wrong.


To understand the connection, we need to look at what conditions make for the heaviest snowfalls. Then, we can look at how climate change is affecting those conditions, especially temperatures in the atmosphere and oceans, during winters. Studying these factors reveals that there is a higher chance of heavy snow storms in North America but the length of the snow season is already shrinking due to global warming.

There is a saying that it can be “too cold to snow”! Of course, this is a myth but it has a basis in fact because the atmosphere gets freeze dried when it is very cold. That’s because the amount of moisture the atmosphere can hold depends very strongly on temperature. Under cold conditions, the snow is likely to consist of very small crystals and sometimes is very light and fluffy and like “diamond dust”.


By contrast, the heaviest snowfalls occur with surface temperatures from about 28°F to 32°F – just below the freezing point. Of course, once it gets much above freezing point, the snow turns to rain. So there is a “Goldilocks” set of conditions that are just right to result in a super snow storm. And these conditions are becoming more likely in mid-winter because of human-induced climate change.

You are right, very cold temps usually are accompanied with lower snow accumulation. However, this year, the farmer almanac (which I have been surprised to see gives the most accurate weather forecast compared to all the new meteorological technology and their predictions) Environment Canada, the Weather network, all predict the unusual forecast of colder than normal temps with above normal snow falls.

I don't write it I just read it. Could be a very difficult winter is all I'm saying. Quite the contrast to the summer that we just suffered through.

I can relate, however, I fix furnaces so I'll be hoping & praying for snow and cold. Cha ching!

Sorry Brother but I need the coin.

Could happen. We've never gone through change this rapid and profound. The acceleration of warming, for example, caught scientists by surprise.

So the more things change, the less predictable they will be. Still, the phase diagram of water will not change. So extreme cold should not produce heavy snows.
 
NOAA thinks it won't be as warm this winter as last, but still mostly warmer than normal.

From what I understand, the El nino has passed and we are now going to get colder air from the north meeting with the warm water of the great lakes. This produces large amounts of "lake effect" snow. I don't have any personal ability to predict what or why.

The lake effect only works if the lake isn't frozen over. It's another reason why warmer winters tend to blanket states and provinces around the Great Lakes. That doesn't mean much for the East coast, of course. There, the reduced amount of water vapor that can be held in colder air is more important.

It is very rare that the great lakes freeze over. However, in some rare years, even Niagara falls froze solid.

Lake Erie used to freeze up about 70% of the time. It's shallower, and easier to freeze. Superior is much deeper and harder to freeze. I think Superior last froze over about 2009.

Ya, Erie is shallower. For the most part, there is enough open water for lake effect snow. Especially this year as the water temps are higher due to the massive amounts of sunlight hours we got this year. Combine that with cold air from the north, as the jet stream dips into the mid states and we get dumped on.
 
As fewer bays ice up, it will increase the amount of water surface. If the air is relatively warm, more moisture will go into the air, and thereby there will be bigger snowfalls.
