Carbon Dioxide Fertilization Greening Earth, Study Finds

Well this is certainly some good news!

Considering that atmospheric carbon dioxide is food for plants on both land as well as in the oceans it is logical that higher levels of CO2 in the atmosphere will benefit many plants.

Carbon Dioxide Fertilization Greening Earth, Study Finds
From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25.

An international team of 32 authors from 24 institutions in eight countries led the effort, which involved using satellite data from NASA’s Moderate Resolution Imaging Spectrometer and the National Oceanic and Atmospheric Administration’s Advanced Very High Resolution Radiometer instruments to help determine the leaf area index, or amount of leaf cover, over the planet’s vegetated regions. The greening represents an increase in leaves on plants and trees equivalent in area to two times the continental United States.

Removal of carbon dioxide ‘no silver bullet’: scientists
Fri, Feb 02, 2018 - IMPRACTICAL: While some technologies could have a role to play, all have drawbacks making them difficult to use on a large scale, a climate expert said

Technologies to remove carbon dioxide from the atmosphere to help tackle global warming only have limited potential and more effort should be made to reduce emissions, European scientists said in a report on Wednesday. Proposals to use climate technologies, ranging from spraying sun-dimming chemicals high above the Earth to capturing and storing carbon dioxide underground, have been gaining more attention as the urgency to act on climate change mounts. Under the 2015 Paris Agreement, world governments have agreed to limit global warming to well below 2?C above preindustrial levels, but a large gap remains between nations’ emissions plans and the reductions needed.

The European Academies’ Science Advisory Council, formed from the national science academies of EU members, has reviewed scientific evidence about several options for removing carbon dioxide from the atmosphere with so-called negative-emission technologies. Examples of such technologies include the direct capture of carbon dioxide and trapping it underground (carbon capture and storage); afforestation and reforestation; land management to increase and fix carbon in soils; and ocean fertilization. The council, which advises European policymakers, said these technologies have “limited realistic potential to remove carbon from the atmosphere” and not at the scale in some climate forecasts, such as several gigatonnes of carbon each year after 2050.

Their deployment on a large scale would also involve high economic costs and have major impacts on terrestrial or marine ecosystems, the council said in the report. “Technologies capable of taking out CO2 [carbon dioxide] from the atmosphere are certainly no silver bullet — a point that should drive policymakers to renewed efforts to accelerate emissions reductions,” the report said. However, the world will need all possible tools to limit warming and some of these technologies can make contributions to remove carbon dioxide from the atmosphere even now, while further research, development and demonstration might allow others to make a limited future contribution, it added.

Commenting on the report, Andrew Watson, Royal Society research professor at the University of Exeter, said that while some technologies for removing carbon dioxide from the atmosphere could have a role to play in reducing climate change, all have drawbacks making them difficult to use on a large scale. “So our main focus and best hope for avoiding the worst effects of climate change still needs to be reducing our emissions,” Watson said. Last week, a leaked draft UN report said there is a high chance that the levels of carbon dioxide removal which might be required to meet the Paris goals might not be feasible due to the required scale and speed of technology deployment.

So true!

Earth has a way of finding balance

Yup, trees and plants would be thankful for more carbon dioxide.

And they sure wouldn't mind more and more and more desalinated ocean water either......

The Sahara Forest Project...and saving New Orleans and Florida from rising oceans!

Did you know that there is an Islamic prophecy that the Islamic desert regions would be turned green in the latter days?????

This topic is of special interest to me because I live about a hundred miles from the Bay of Fundy. I live five kms from the ocean on the eastern part of Nova Scotia. In my area the difference between low tide to high tide is about one meter! The land form of the Bay of Fundy has a funnelling effect on tidal waters and so parts of the Fundy have a difference of fifteen to seventeen meters between low to high tide!

The question on my mind would be if ocean levels were to rise about thirty centimeters in my part of Nova Scotia, would they rise by four or five meters along parts of the Fundy????

There are 143,000 acres of farmland taken back from the Fundy by dikes that are probably in the position of the proverbial canary in a coal mine in relation to rising ocean levels!

Every cubic meter of H2O added to the water table of nations in the Middle EAst will NOT be on top of New Orleans, Florida, Holland, Bangladesh or those 143,000 acres along the Fundy!!!!!

I felt a huge sense of relief when I first heard about The Sahara Forest Project!
