But the targets set \u2014 a 17% cut in CO2 and other greenhouse gas emissions by 2020 and 80% by 2050 \u2014 will likely not be enough to counter global warming. This is why researchers are looking into bioengineering techniques such as large-scale carbon dioxide sequestration or increasing the planet&#8217;s <a title=\"d\u00e9finition de alb\u00e9do\" href=\"http:\/\/fr.wikipedia.org\/wiki\/Alb\u00e9do\" target=\"_blank\" rel=\"noopener\">albedo<\/a>.<\/p>\n<p>The study aims to assess the feasibility, effectiveness and impacts of a selection of techniques. The fact that some of these technologies are inexpensive and relatively simple to deploy raises an additional security concern, as certain countries or even <a title=\"Article du Figaro sur la tentative de fertilisation des oc\u00e9ans par un particulier\" href=\"http:\/\/http:\/\/www.lefigaro.fr\/environnement\/2012\/10\/17\/01029-20121017ARTFIG00690-climat-un-americain-tente-une-experience-risquee.php\" target=\"_blank\" rel=\"noopener\">wealthy individuals could unilaterally decide to implement them<\/a> without regard for the consequences.<\/p>\n<p>The study, which has a budget of $630,000 and is expected to run for 21 months, will focus on the following two types of technology:<\/p>\n<p>. solar radiation management (SRM), such as releasing sulphur particles into the stratosphere to reflect sunlight (the idea being to mimic the effect of volcanic eruptions)<\/p>\n<p>. carbon dioxide removal (CDR) and carbon capture and storage (CCS), for example by <a title=\"Article de Sciences &amp; Vie sur la fertilisation des oc\u00e9ans\" href=\"http:\/\/sciencesetavenir.nouvelobs.com\/nature-environnement\/20090324.OBS0463\/fertilisation-des-oceans-un-predateur-s-invite-a-table.html\" target=\"_blank\" rel=\"noopener\">fertilising the oceans<\/a> with iron sulphate.<\/p>\n<p>Some climate manipulation experiments have already taken place.
