<span style="font-size:12.0pt">1. Planting large numbers of trees to draw down carbon is an easy, common sense way to deal with the climate crisis. Gigantic projects are underway. They
<span style="mso-spacerun:yes"> </span>may do more harm than good, or less good than some alternative actions (or inactions). Smart forestation and reforestation projects require careful planning. For example: “ Depending on soil types and climate, grasses
often use less water to sequester soil carbon than trees do, and can do so faster and more effectively at higher temperatures. Grasses are also less vulnerable to destruction by fire, drought, and disease.”

sequestration. </span><a href="https://www.theguardian.com/environment/2021/apr/09/sea-rice-eelgrass-marine-grain-chef-angel-leon-marsh-climate-crisis"><span style="font-size:12.0pt">https://www.theguardian.com/environment/2021/apr/09/sea-rice-eelgrass-marine-grain-chef-angel-leon-marsh-climate-crisis</span></a><span style="font-size:12.0pt"><o:p> </o:p></span></p>

have lots of new sea meadow space.) <span style="mso-spacerun:yes"> </span></span><a href="https://www.reuters.com/article/us-climate-change-seagrass/shrinking-sea-meadows-store-more-carbon-than-forests-scientists-are-racing-to-track-whats-left-idUSKBN2BV0MV?edition-redirect=uk&utm_campaign=Carbon%20Brief%20Daily%20Briefing&utm_content=20210409&utm_medium=email&utm_source=Revue%20Daily"><span style="font-size:12.0pt">https://www.reuters.com/article/us-climate-change-seagrass/shrinking-sea-meadows-store-more-carbon-than-forests-scientists-are-racing-to-track-whats-left-idUSKBN2BV0MV?edition-redirect=uk&utm_campaign=Carbon%20Brief%20Daily%20Briefing&utm_content=20210409&utm_medium=email&utm_source=Revue%20Daily</span></a><span style="font-size:12.0pt"><o:p> </o:p></span></p>

<span style="font-size:12.0pt">5. Harold Wanless, a coastal geography professor at the U of Miami, is arguably Florida’s most prominent scientific voice on climate. He warns that our planning for sea level rise is not up to the levels we must expect. “Rather
than building more in low-lying regions and spending public money on coastal defenses that are bound to fail, we should prepare to assist the eventual relocation of people and infrastructure from the most threatened areas (and clean the land before inundation).”
