It is expected to be ready for trials in about two years. </span><a href="https://www.anthropocenemagazine.org/2023/02/engineers-devise-simple-system-to-capture-co2-from-oceans/?utm_source=rss&utm_medium=rss&utm_campaign=engineers-devise-simple-system-to-capture-co2-from-oceans" class=""><span style="font-size:12.0pt">https://www.anthropocenemagazine.org/2023/02/engineers-devise-simple-system-to-capture-co2-from-oceans/?utm_source=rss&utm_medium=rss&utm_campaign=engineers-devise-simple-system-to-capture-co2-from-oceans</span></a><span style="font-size:12.0pt"><o:p> </o:p></span></p>

to 67m running cars.” Methane could be the largest single threat to meeting the Paris heating goals. 55 new sites pose an additional threat.

half the cost of developing pilot processes which reduce those emissions. Cement, steel, and chemical manufacture are among the processes covered by the Industrial Demonstrations Program.

energy which drives the production must come from renewable sources. The role of H2 as a secondary greenhouse gas is not mentioned.

is hard to find, though it will roast us as yet another greenhouse gas, even if at a reduced rate.<span style="mso-spacerun:yes">

to AR5 (Primarily Hazardous). The scale will make it easier to convey warnings of the severity of the events.
