According to two different studies published in Nature in the past couple of years, none of the developed nations that signed the Paris Agreement is on course to accomplish its goals to reduce GHG emissions to predicted levels, but even if all parties to the Agreement were to achieve their targets, it still wouldn't result in limiting global warming to 2°C above pre-industrial levels.
No major advanced industrialized country is on track to meet its pledges to control the greenhouse-gas emissions that cause climate change.
Prove Paris was more than paper promises
The INDCs [Intended Nationally Determined Contributions] collectively lower greenhouse gas emissions compared to where current policies stand, but still imply a median warming of 2.6–3.1 degrees Celsius by 2100.
Paris Agreement climate proposals need a boost to keep warming well below 2 °C
It's difficult and expensive to quickly convert the world's grand fossil-fuel-based infrastructure of power production. And one of the major obstacles, rarely mentioned in popular media, is the fact technology does not currently exist for adequate battery storage in order to supply continual power from wind and solar sources. Adding to this problem is the fact that hydropower is often considered a "green" and "renewable" source of power, despite that damns are often extraordinarily ruinous to the environment, and many times emit more GHGs in CO2e than the same amount of energy produced by fossil fuels. A further obstacle is the current irrational fear of safe, clean nuclear power, despite the fact that designs of travelling wave reactors are now available that render the plants meltdown-proof and the fuel proliferation-proof.

The Real Obstacle to Responsibly Meeting the World's Energy Needs Is Not Unbelief in AGW
Against this backdrop glimmers various other related issues such as the fact that we could rapidly improve numerous environmental problems, besides climate, by changing our diet. In a recent article spotlighting two newly developed products, Beyond Burger and Impossible Burger, the UN Environment Programme cited a few facts illustrating the article's title, that "the world's most urgent problem" is meat, noting inter alia that GHG emissions resulting from animal agriculture is at least equal to that of all forms of transportation combined, that roughly "80 per cent of agricultural land is used to make livestock feed or for grazing," and that while all the buildings, roads, parking lots and other paved surfaces take up less than 1% of the earth's land surface, more than 45% of the planet's land surface is used for grazing or growing feed for livestock. In stark contrast:
According to a research study conducted by the University of Michigan, a quarter-pound Beyond Burger requires 99 per cent less water, 93 per cent less land and generates 90 per cent fewer greenhouse gas emissions, using 46 per cent less energy to produce in the U.S. than its beef equivalent.
Tackling the world’s most urgent problem: meat
The Impossible Burger, developed by Dr. Patrick Brown, founder of PLoS, requires "approximately 75 per cent less water and 95 per cent less land, generating about 87 per cent lower greenhouse gas emissions than beef burgers."
The article, published before the recent IPCC Report, utilizes the product developers to express the fact that "there is no pathway to achieve the Paris climate objectives without a massive decrease in the scale of animal agriculture". It seems that, unless a lot of scientists are really wrong about the AGW hypothesis, limiting global warming to a non-catastrophic level will not happen without a massive decrease in animal agriculture.
Yet in its recent report, the IPCC clearly remains focused on CO2 emissions, particularly those produced by fossil-fuel burning for energy production and transportation, and gives only secondary consideration to "non-CO2 forcers"--its category for other GHGs. This is despite such facts as that a molecule of methane packs a whopping 84 times the global warming potential of a CO2 molecule (using a 20-year time frame), and livestock alone contribute about 40℅ of anthropogenic methane emissions. Methane's short half-life means that global temperature could be rapidly affected by a reduction in its emissions.
IPCC's models limiting warming to 1.5°C (which isn't going to happen) entail net zero CO2 emissions by 2030 with only various unspecified reductions of non-CO2 emissions.
But perhaps the most confounding aspect of IPCC's analyses is the denigration of carbon removal techniques. Apparently none of its analyses includes consideration of carbon removal technologies or reforestation until there has been an "overshoot" of target warming, and even then, the Report repeatedly warns that there are "uncertainties and clear risks" of carbon removal techniques. Technical Summary, p. 7
IPCC - SR15
Yes, there are undoubtedly big uncertainties in these techniques, but none greater than the near-certainty that the world will fail to achieve net-zero CO2 emissions from fossil-fuel burning in the next few decades.
But what are the risks of atmospheric CO2 removal or capture technologies? As best as I can decipher the IPCC's soporific Report, the risks are simply that these technologies may be ineffective. One could easily get the impression that IPCC is more interested in countries following a script about curtailing use of fossil fuels than doing what's doable and less painful in limiting global warming.
Ponder the following device, for which the inventors
. . . calculate that given an area less than 10 percent of the size of the Sahara Desert, the method could remove enough carbon dioxide to make global atmospheric levels return to preindustrial levels within 10 years, even if we keep emitting the greenhouse gas at a high rate during that period.
New Method Removes Carbon from the Air, Churns Out Valuable Carbon Products
Switzerland has had a carbon removal contraption since last year:. http://www.sciencemag.org/news/2017/06/switzerland-giant-new-machine-sucking-carbon-directly-air
(which doesn't look at all like what I thought these devices would look like--I always imagined something that looks like a flying bagpipe).
So, several questions:
Why shouldn't the world be encouraged to develop and implement such carbon removal technologies?
In your opinion, what is the reason the IPCC is so dismissive of CO2 removal technologies?
And given two choices, where neither is more or less convenient or costly to do, but one is much more environmentally harmful than the other, should not one do the one that is less environmentally harmful?
