In Nepal, waterfalls are roads

eric3579 says...

This is the Besisahar-Chamé Road( https://goo.gl/SeMX4Q ) in the Manang District of Nepal.

When i was traveling in Nepal (over 20 yrs ago) I took a bus from Kathmandu to Pokhara on a then dirt road that had crazy cliffs and no guard rails at all. We also road on top of the bus with the luggage on the trip back to Kathmandu. It's crazy how close they had to drive to the cliffs edge. Looking at the road now, on google maps, it seems quite harmless as it's all paved.

The Nepalese 7.9 earthquake also wiped out the Everest camps

Meaning; it didn't occur to me that Nepal/Everest WAS earthquake country--but in places like California, one generally takes care not to sleep with things secured over the headboard of the bed and you bolt things to the wall (bookcases)---to camp in the slide zone of an ice cliff in such a region might give one pause...

I'm guess from you're tone your American, or at least only figure Americans are going to be reading? You note that 'we' can't get to the moon, while Chinese rovers navigate it's surface. You note with alarm what coastal Florida will face from sea level rise, and not an entire nation like Kiribati. When we look at a global problem we can't ignore technology just because it's Chinese, or focus so hard on Florida's coast we ignore an entire nation in peril.

Sea levels aren't going to be fine in 2099 and then rise a foot on the eve of 2100. They will continue to rise about 3mm annually, as they have already for the last 100 years.(on a more granular level slightly less than 3mm nearer 1900 and slightly more nearer 2100 but the point stands). Coastal land owners aren't merely going to see this coming. They've watched it happening for nearly 100 years already and managed to cope thus far. Cope is of course a bad word for building housing near the coast and at less than a foot above sea level. It's like how occupants at the base of active volcanoes 'cope' with the occasional eruption. All that is to say, the problem for homes built in such locations has always been a matter of when not if disaster will strike. The entire island nation of Kiribati is barely above sea level. It is one tsunami away from annihilation. Climate change though is, let me be brutally honest, a small part of the problem. A tsunami in 1914 would've annihilated Kiribati, as a tsunami today in 2014 would, as a tsunami in 2114 would. And we are talking annihilate in a way the 2004 tsunami never touched. I mean an island that's all uninhabited, cleared to the ground and brand new, albeit a bit smaller for the wear. That scenario is going to happen sooner or later, even if the planet were cooling for the next 100 years so let's be cautious about preaching it's salvation through prevention of climate change.

Your points on food production are, sorry, wrong. You are correct enough that local food growth is a big part of the problem. You are dead wrong that most, or even any appreciable amount is to blame on climate change now or in the future. All the African nations starving for want of local food production lack it for the same reason, violence and instability. From this point forward referenced as 'men with guns'. The people in Africa have, or at least had, the means to grow their own food. Despite your insistence that men with guns couldn't stop them from eating then, they still did and continue to. A farmer has to control his land for a whole year to plant, raise and harvest his crop or his livestock. Trouble is men with guns come by at harvest time and take everything. In places like the DRC or Somalia they rape the farmer's wife and daughters too. This has been going on for decades and decades, and it obviously doesn't take many years for the farmer to decide it's time to move their family, if they are lucky enough to still be alive. That is the population make up of all the refugee camps of starving people wanting for food. It's not a climate change problem, it's a people are horrible to each other problem. A different climate, better or worse growing conditions, is a tiny and hardly worth noting dent in the real problem.
CO@ emission restrictions do not equate to global economic downturn, they could just as easily mean global economic upturn as new tech is adopted and implemented.
I stated meaningful CO2 emission changes. That means changes that will sway us to less than 1 foot of sea level change by 2100 and corresponding temperatures. Those are massive and rapid reductions, and I'm sorry but that can not be an economic boon too. I'm completely confident that electric cars and alternative or fusion power will have almost entirely supplanted fossil fuel usage before 2100, and because they are good business. Pushing today though for massive emission reductions can only be accomplish be reducing global consumption. People don't like that, and they jump all over any excuse to go to war if it means lifting those reductions. That's just the terrible nature of our species.

As for glaciers, I did read the article. You'll notice it observed that increasing the spatial resolution of models changed the picture entirely? The IPCC noted this and updated their findings accordingly as well(page 242). The best guess by 2100 is better than 50% of the glaciers through the entire range remaining. The uncertainty range even includes a potential, though less likely GAIN of mass:
. Results for the Himalaya range between 2% gain and 29% loss to 2035; to 2100, the range of losses is 15 to 78% under RCP4.5. The modelmean loss to 2100 is 45% under RCP4.5 and 68% under RCP8.5 (medium confidence). It is virtually certain that these projections are more reliable than in earlier erroneous assessment (Cruz et al., 2007) of complete disappearance by 2035.

If you still want to insist Nepal will be without glaciers in 2100 please provide a source of your own or stop insisting on contradicting the science to make things scarier.

Slow down with the theories that our 'advancements' will solve all problems, not create more, because all the things you listed have been fairly disastrous in the long run, many being large parts of the issue at hand, climate change, and things like putting a man on the moon or traveling the globe in hours have gone backwards, meaning it was simpler to do either 35-45 years ago than it is today (we can't get to the moon with NASA today, or get on a concord). Assuming new tech will come along and solve the problems we can't solve today is wishful thinking, assuming they'll come with no strings attached means you aren't paying attention, all new tech is a double edged sword in one way or another.
IF humans could harness their tech, capital, and energy altruistically, yes, we could solve world hunger, disease, displacement, etc. Humans have never in history done that though.
We already can't feed a large percentage of the planet. If a large percentage of farmable land is lost to sea level rise (won't take much) and also a large population displaced by the same (a HUGE percentage of people live within 10 miles of a coast or estuary), we're screwed. It will mean less food, less land to grow food, more displaced people, less fresh water, fewer fisheries, etc. We can't solve a single one of these problems today. What evidence do you have we could solve it tomorrow, when conditions will be exponentially less favorable?
For instance, something like 1/3 of the population survives on glacial water. It's disappearing faster than predicted. There's simply no technology to solve that problem, even desalination doesn't work to get water into Nepal. People seem to like water and keeping their insides moist, how would you suggest we placate them?

Slow down on the we need to panic soon or we are even too late for panic. The IPCC estimates through to the year 2100 do not show unmanageable changes. We can adapt to the temperature and sea level changes expected. More over, that is based on today's technology. We are talking nearly a hundred years in the future. 100 years ago cars, planes, refrigerators, spaces ships and nuclear weapons were all yet to be discovered or known to the public. Problems like putting a man on the moon or travelling the globe in hours seemed insurmountable then. They are done and a matter of course to us today.

Apologies, but with all due respect panic hardly seems called for over a temperature and sea level increase we can handle currently pending on us in a hundred years. Something tells me it'll give the people then with hundred years of advances more if a laugh than a burden.
