Thread: Climate sceptic? Met 40,000,000 thirsty people

Another factor is the dams placed on the Murray system over the last hundred years or so have greatly reduced the volume of sediment feeding into the longshore drift east of the Murray mouth.

"The Western U.S. is bracing for more extreme weather as some regions prepare for torrential rain and others for continuing extreme heat.
Monsoon rains are forecast to continue over the deserts in the Southwest and up into the Rocky Mountains, with potential for flash flooding in Arizona, Utah, Colorado and Wyoming on Sunday.

"A flood watch is in effect for more than 8 million Americans from Phoenix and Las Vegas all the way into Wyoming as that steady stream of moisture leads to flooding rain.
Among the first places to watch for flash flooding is along the burn scars of recent wildfires.

Suspect erosion is the result for fires then floods.


A lot of rain is needed of course.

Then..... All of a sudden, we are hit with TV news of China's terrible drought, whole rivers dried up.... cutting Hydro generation ... and a reason for them planning to build more (?) COAL fired stations... Y'know, the dirty CO2 belching things wot makes Climate Change .... which warms the planet and causes droughts.

Funny, that said TV News reports were SO delayed in getting here.

Not just hydro going down what was 'The Gurgler'... but farmers with failing / failed crops is causing consternation, and their Economy gunna take a hit. - Who knows what that'll do to their manufacturing output / cheap renewables such as PV arrays and wind turbines !
- Maybe those shortages will bite the rest of the world as much as China. ?

It's all looking a lot like The Day After Tomorrow. Just need the troposphere touching down somewhere and we're there.

its a crazy world- Two legionnaire's cases at work and "A recent study says this amount of ice melt is expected to raise the global sea level by a minimum of 10.6 inches, leading to severe storms, flooding, and higher tides.
During the good old days in Greenland, endless ice seemed a permanent part of the landscape—but its future is destined to look much different. The warming power of climate change is enough to chip away at chunks of frozen ice sheets called “doomed ice” and “zombie ice” that will melt and raise the global sea level by at least 10.6 inches, according to a study published Monday in the journal Nature Climate Change."

Some dayz it seems nuts yet other bits seem so cool I may be happy?

Cooked the coolest steak. Grated parsnip, chilli, mint, lime, spring onion, fried beans on rice omg it rocked and my design so even happier fish sauce, Mirin, sugar and and few other bits....

More water more fish? Not sure if it helps all drought areas of course.

"Zombie ice from Greenland will raise sea level 10 inches

"

Great headline? Link

How much is a given and how much more??? "The unavoidable ten inches in the study is more than twice as much sea level rise as scientists had previously expected from the melting of Greenland’s ice sheet. The study in the journal Nature Climate Change said it could reach as much as 30 inches (78 centimeters). By contrast, last year’s Intergovernmental Panel on Climate Change report projected a range of 2 to 5 inches (6 to 13 centimeters) for likely sea level rise from Greenland ice melt by the year 2100."

Bragging about 9 or 10 inches is not proper? I had to check. It is 25.4cm

what I was looking for was date/time for the 25.4 cm ocean rise to be effective , which appears to be in 75yrs , which equates to 3.5mm. approx sea level rise per year.

ok you mathematicians who love a good challenge.....if we get an ocean rise of any significance, then river systems flowing to the sea will remain that amount deeper...ok? agreed?

that means that Khati Thanda will hold more water progressively. If the lake deepens by the 25,4cm how much larger will its surface area become?

will William Ck be under water?

btw , there is a lot more ice melting than just greenland.

none of you reading will need a boat.....you'll be dead

No. River gradients will have changed, but it won't be that simple. The gradient (and hence flow rate) close to the see will decrease, so the river will spread out more, but once the current river surface gets more than a metre or so above sea level the river will not change. not immediately anyway, but the lower flow rates near the mouth will lead to increased sediment deposition, which will progressively obstruct the river upstream, but only slowly.
