Humans live of mimetism almost entirely (very little true innovation out of our lives). Historically, the trend-setters have been western countries. If western countries don't clean their own shit, others won't follow (note that I

Does it matter if people drive 10000km over a year for business meetings or if people go to a conference once a year by plane?

The article is 6 months old and the study it's based on is more than 1 year old. How is the project? There are rare earth minerals everywhere. Even when they are economically viable to extract, most countries are unwilling to, because

Bangladesh is not suffering of famines? Africa is suffering of famines, and the land use is far from saturated. Furthermore, most of the planet except Africa has a fertility rate below 2.5 already (Bangladesh at 2.4). The biggest reason for

Technically, we didn't pass it completely (0.8C). https://climate.nasa.gov/vital-signs/global-temperature/ 2016 reached 1C of warming anomaly relative to 1951-1980 average, but was exceptionally hot. But ther

Very important article. A point that failed to be mentioned is this one : as the mining demand goes up, more and more "low-concentration" mines will be opened, requiring more energy to extract the same amount of raw materials. And

You're being intellectually dishonest here. Relocalizing industry is a controlled process, where the direction of the flux of people is known, and housing and infrastructure sizing can be planned and handled, and people won't foll

Just like growing soy to feed beef, like we do now, except that we found out that the cheapest way to do that was to cut down trees in the amazon forest, grow it there and ship it to the US. Uncontrolled innovation may have unexpected resul

Of course I have seen stuff like this. How much seaweed needs to be produced, won't this have other ecological repercussions? Why is this presented as a kill-all-worries innovation? A much simpler and less crazy solution is simply to h

This will cost a lot, and this is not even the hardest step. We use energy for electricity, but also transportation, heating, fertilizer production/agriculture, cattle produces GHG, A/C recycling, and what not. The USA will need t

I am a proponent of nuclear, but wouldn't use of extra energy during off peak times apply to renewables even more so? Unless there are massive improvements in efficiency and cost-effectiveness of storage, adapting usage to production o

Another reason for the "country’s shrinking appetite for nuclear" that I can cite is the North Korean terrorist threat. Rationally, there is little reason for the North Korean state to cause long term damage to a soil that they cl
