There's no good news these days when it comes to climate change...everything is either worse than we expected, or merely just as bad.

An unexpected melting of Antarctic ice might trigger 2 metre sea level rise: http://ow.ly/105Rtb
The current deployment of Sulphate aerosols introduced into the atmosphere for SRM Solar Radiation Management, Solar Geoengineering, will help slow the pace of melt.
ReplyDeleteIt's way worse than the 'common folk' know about...It's going to be the snowball effect, then the straw which breaks the camels back. I will be an elderly man in that time. Makes me want to purchase a handgun specifically for suicide in case the air is too hard to breathe or mass unrest. But I think I'll just ride it out.
ReplyDeleteWarmer temps will also shift the major currents and affect commerce by sea.
ReplyDeleteBob Lai that's insight I would've never thought of from the inland. But, that's a major event as well.
ReplyDeleteI thought that the Antarctic just recorded record high ice sheet extent.

OK so that's 2014, but still...
Also, don't believe the hype, the melting ice sheets are just great for visually representing the warming. The real sea rise comes from the thermal expansion of the entire ocean. A tiny amount of thermal expansion over a massive volume makes sea rise.
Remember ice sheets that are floating are already displacing the same amount of water they contain so there's no net sea rise from melting all floating ice. Its the ice over land that is the problem.
Sure, the displacement occurs any ice above surface (of ocean water) which melted or chunked off.
ReplyDeleteRicky Aranda.. No.. Not just above surface of ocean.
ReplyDeleteHow do you think it floats?
Look up how displacement and buoyancy works.. Floating ice in a cup of water is the same water level when it melts. Do the experiment yourself.
Float ice in water.
Measure the water line.
Note that there is ice above the line.
Wait for the ice to melt..
Check the line. Its the same.
That's how displacement works.
Let us see what's going to happen to mankind
ReplyDeleteRob Mellor No, actually frozen water (ice) takes up more room. So underwater ice when melted will take up LESS room as water. Only the above sea level / on ground ice will increase sea level. With 90% of an iceberg underwater, sea level rise should be negligible.
ReplyDeleteI'm not saying man made climate change is false, it's very true, and that warm waters will cause horrible harm - it will - but science shouldn't be forgotten.
Dino D Fantozzi we are saying the same thing. I'm saying that the amount of water displaced by a floating ice berg results in the same water level. The ice floats because it takes up more volume, hence has a lower density. Water is at it's most dense at 4degrees, the sea level rise will be mostly from thermal expansion.
ReplyDeleteRob Mellor been a long time since I rock and rolled with basic principles. I don't think about the general principles ever including how a glass gets frosty. Lol. Mostly into politics. thanks so much for refuting that gentleman's assertion. so embarrassed, third grade for u.s. Sci class, kindergarten for Japanese. Lol. I will do some research on YouTube for a whole weekend, now (science wise) fun science etc. Oh, I feel like an ignoramus.
