Wasn't clear to me if 2015 would have been hotter than 2014 had it not been an El Niño year.
>2015’s sharp spike in temperatures was aided by a strong El Nino weather pattern late in the year that caused ocean waters in the central Pacific to heat up. But the unusual warming started early and steadily gained strength in a year in which ten of 12 months set all-time records, scientists said.
Nuclear Power, until those who care about the environment accept that the only clean at scale power solution for base load is nuclear power we will get no where. "Renewables" are great and should be in the mix but they are not an at scale solution. http://www3.epa.gov/climatechange/images/ghgemissions/source... By going mostly electric for our transportation and nuclear for power generation we could really make a den…
Nuclear is fantastic for base load, but peak load? Steam bypassing costs as much as generating electricity does, but with nobody wanting to pay for power they didn't use. Technically a good solution, but falls apart economically.

Lots of people keep saying this, but I really don't think it's true. Solar and wind work fine at scale. There is nothing un-scalable about them. What they don't do is work at night, and in that case nuclear is a fine option. Although batteries that can run a house overnight aren't that expensive.

>> It's just nuts, really, something is terribly wrong with our world, and we need to fix it. You should probably start with developing countries like China and India. The US has been actively reducing its carbon footprint for a while now: Energy related carbon emissions in the United States declined by 12% between 2005 and 2012, back to a level not seen since 1994. Per capita emissions fell 17% over the same period,…
Per-capita CO2 emissions by countries, 2011: US 17.0t China 6.7t India 1.7t Yeah, we should totally talk to China and India. Source: http://data.worldbank.org/indicator/EN.ATM.CO2E.PC?order=wba...
By that metric China is among the worst in the world and India isn't far behind.

Total CO2 emissions by countries, 2014: US 5.3 Gt China 10.5 Gt India 2.3 Gt Yeah, China and India are totally relevant to global CO2 emissions. The global climate doesn't give a damn about how many people are responsible for a given quantity of emissions, it's completely and utterly uncaring.

Okay - help someone that doesn't truly understand this. Earth's surface can gain heat through 4 ways I can think of (and this is just what I can think of and is likely wrong): 1) Geothermal brings more heat from core/mantle up. I don't think this is currently any larger than normal, nor do I imagine this varies much. 2) Oceans can give up heat they are storing and provide it on the surface. I don't know if El Nino is…
The Earth can only "gain" heat through #3, solar radiation. The other 3 items you list can store and release heat at a later time, but they can not generate more heat than they already possess now. (This is not strictly true, conversion of mass to energy, e=mc^2, means that nuclear and fusion energy could create new heat at the expense of matter, but we generally assume that on planets, this is negligible.) So if peo…
