Even if that were true (which it is definitely not), you need to have 30 year averages showing a clear trend to say anything about climate change. Otherwise, you can attribute it to the random forcing of weather and decadal variations of things like El Nino, sunspot activity, PDO, AMO, etc.

Clearly you didn't read some of the previous posts. A bunch of people were still trying to say the earth is cooling hurr durr weather and climate are the same thing.

As for severity? We have climate models and pretty decent guesses for how things will be in the next 100 years or so. And fairly exact figures for the damage that we have already done.

Earth will be ok in 200 years even if we make no changes. Different, but liveable.

I'm not against nuclear by any means, I just don't think a lot of people realize this isn't a "renewable" resource either and there is a finite amount of Ur and Pl we can mine from Earth or reprocess from previous plants.

I agree, we are taking some big steps towards sustainability as a planet. There is still a lot of work to be done though. Finally we are at the tipping point where it's starting to make more sense to go with solar or wind.

I keep getting the numbers for GHG forcing wrong.

Probably because I can't believe they are so high.

+3 W/m^2 for GHGs - 1 W/m^2 for aerosols = +2 W/m^2 net radiative forcing caused by humans.

Should have been obvious if you opened the figure, but I couldn't just leave it be.

For climate science, anytime.

My post was actually a partial repost of my comment over this B/S article I found on reddit (before my 4chan days) that pissed me off enough to respond:

Fuck you if you believe this article and get off /sci/ ^

How are there so many global warming skeptics on /sci/??

CO2 was recently measured at 400 ppm (parts per million) in the Arctic. This is mostly a psychological milestone as a reminder that atmospheric CO2 levels are presently higher than they have been in AT LEAST 500,000 years as shown by multiple, ice core project datasets from Greenland and Antarctica (they don’t go any further back than ~420 kyr). (Petit et al, 1999)

As for the “missing energy” argument that we’ve all been hearing for years, it has been solved by NASA’s CERES team this winter! The “missing energy” we thought should be somewhere in the earth-atmosphere system is being stored as heat in the OCEAN. In fact, about 90% of the heat that is a result of increases in greenhouse gas concentrations is currently being stored in the ocean, and, when this heat released to the atmosphere, it has the potential to warm the atmosphere by .5 degree C. See this NASA article:
http://www.jpl.nasa.gov/news/news.cfm?release=2012-029

There IS excess energy in the ocean-atmoshpere system, and it IS caused by human emissions of GHGs. The current radiative forcing estimates of anthropogenic greenhouse gases (CO2, methane, etc) are right around +2 W/m^2, counteracted by about -1 W/m^2 due to aerosol radiative forcing, which leaves the NET anthropogenic radiative forcing (i.e. global WARMing magnitude) of approximately +1 W/m^2 (IPCC, 2007). It may not sound considerable, but over time, this figure alone has the potential to significantly change the planet as we know it.

tl;dr come on guys...we are all scientists here

space-time is warped within a certain range of a black hole, where the gravitational field is so strong that nothing (not even massless photons) can escape.

My, slightly diluted understanding. Definitely not intuitive stuff though, to me at least. Good Q.

nanobots performing surgeries all over the world.

I don't know how far along we are with this tech, but I think we are pretty close and it sounds really promising to me.

Cool thanks. I will look into this.

I dunno about synthetic meat, but veggie burgers and morning star veggie chicken and sausages are all dank.

I was a vegan for over a year a few months ago. Now I eat meat and dairy occasionally again since I'm not with a vegan gf anymore lol. It wasn't bad though, and I felt healthier than ever before.

tl;dr don't support factory farms...go veg

>>4855342
Lol.

It's a valid question though. How would you even go about doing this OP? Is there any risk or performance consequences? Those are the things I would be worried about at least.

>>4855211

Yes and you're on the right track. Except in your code d has no dependence on a or b, it will just loop through and do that same line (x=5d) 9 times.

Google: MATLAB Multidimensional Array

Initialize your vars x and d above the loop btw (ex x=0)

>>4853870

Yup pretty much

There are mountains west of the deserts too, I just named the biggest range I could think of.

There is also large scale sinking air around this latitude (subsidence) as described by the Hadley cell model. 30N and 30S are pretty much where all the worlds deserts are.

^ What he said. The Rocky Mountains and general topography of the American West/Southwest acts to steal most of the moisture in the air before it descends to lower elevations, where it is usually lacking moisture until it finds another forcing mechanism.

Also, the SW USA is very affected by certain climate modes, especially ENSO. If it is a strong El Nino by this winter, the SW mountains will have a hell of a winter!

NASA, 80k with great gov't benefits

Because it's more interesting than any other career choice

>>4852988

Lol, I'd be totally for the switch.

Would you prefer years since the birth of the universe? It would be about year 13.700,000,014 right now.

Perl

Python good too.

MATLAB or IDL are musts for publication quality figures and dealing with big datasets in scientific formats like .netcdf in my field.

All I know is that for graduate level civil engineering, it's one of the top 5 in the USA.

UT Austin I mean, not Emory

Yeah man I've had these thoughts too sometimes.

I don't believe in heaven/hell or anything but someone far crazier than I was convinced we were in hell as humans on earth. Made sense to me, there is a lot of suffering in this world. Some have physical suffering, while others have emotional and spiritual suffering. I've been trying to find the middle ground for a while now.

Nothing we can do in our lives actually "matters" on a universal or even geological scale. Sucks, but accept making small differences.
