Not really. There's something called the "Forest Carbon Cycle". Forests do not statically capture carbon long term. They are constantly taking carbon in but also releasing it through the death of trees and through the soil. Trees can temporarily capture carbon, but ultimately it will be released again unless they are burned. They also take up a lot of space. [EDIT] I should probably clarify that I have nothing agains…

I would love to see engineered wood, like Cross-laminated timber, replace concrete as a structural building material.

>Be constructive, be creative. Ok, solution time. Let's immediately ban everyone who denies that climate change is human made from all positions of power. That implies stripping them of both titles and wealth.

I vote we kill you first. You breathe out CO2, right? EDIT: Nice silent edit there. Let me just quote what you just deleted from your comment "Since they won't probably give in voluntarily and since many of them are already in power, this further implies a violent uprising."

IMO a large part of the failure to deal with this problem has to do with political cowardice on the part of the left. Sometimes if you're just honest with people as opposed to constantly trying to sugar coat, lie, or guilt trip people things go better. It's truly baffling to me that dim-witted local politicians can constantly convince local populations into tax increases and blowing up of local coffers to build sport…

How does animal agriculture affect this? Are there any authorities on the subject on HN? Everything I've heard suggests the greenhouse gas emissions in support of animal agriculture far outstrip those of pretty much anything else, but nobody seems to really talk about it. Pre-empting a couple of replies here - I already don't eat meat, and yes I've seen "Cowspiracy". :)

Animal ag can both be a carbon sink and a carbon source depending on management. Ruminant animals play an important role in grassland ecosystems for nutrient cycling, which can affect the carbon cycle and potentially sequester carbon in soil. Whether we eat the animals is another question. Check out Carbon Farming or Holistic Management for more details.

Vehicles are increasingly being powered by renewables and efficient combined-cycle gas turbines. Coal's share of electricity production is declining or being phased out almost everywhere.

Worldwide the share of coal in energy production is at 40% and the United States it has dropped from 56% to 40%. Coal still produces 40% of every KWh consumed with Nuclear making up a fair portion of the remainder. Renewables are at 20% and (fortunately) rising sharply but for the moment fossil energy sources are by far the bulk of the energy consumed by electric vehicles. http://data.worldbank.org/indicator/EG.ELC.C…
