La temperatura mitjana global s&#8217;ha incrementat en 1,5 graus respecte a l&#8217;era preindustrial, per\u00f2 l&#8217;augment ha estat de 3 graus a l&#8217;\u00c0rtic. Els anys m\u00e9s c\u00e0lids respecte a les mitjanes s\u00f3n cada vegada m\u00e9s freq\u00fcents. Amb aix\u00f2 vull dir que l\u2019increment de temperatures no \u00e9s igual a tot arreu ni totes les plantes s\u00f3n iguals. En aquest sentit, el canvi clim\u00e0tic \u00e9s molt complex. I, per exemple, encara no hi ha un sol estudi sobre la resposta de molses i falgueres.<\/p>\n<p style=\"text-align: justify;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-3481\" src=\"https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas7.jpg\" alt=\"\" width=\"1024\" height=\"768\" srcset=\"https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas7.jpg 1024w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas7-300x225.jpg 300w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas7-768x576.jpg 768w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas7-80x60.jpg 80w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas7-265x198.jpg 265w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas7-696x522.jpg 696w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas7-560x420.jpg 560w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p style=\"text-align: justify;\">Aix\u00ed mateix va comentar que si no es frena el canvi clim\u00e0tic, en general, les plantes subsistiran. Unes es veuran m\u00e9s afavorides i viuran millor, per\u00f2 altres s&#8217;extingiran. Fa milions d&#8217;anys, la concentraci\u00f3 de CO2 era 20 vegades major que l&#8217;actual, per\u00f2 aqu\u00ed interv\u00e9 la segona part de la pregunta de la confer\u00e8ncia: per qu\u00e8 hauria d&#8217;importar-nos com a \u00e9ssers humans. Les plantes s\u00f3n unes reguladores brutals del clima. Poden produir-se despla\u00e7aments geogr\u00e0fics de les esp\u00e8cies productives, la desforestaci\u00f3 t\u00e9 conseq\u00fc\u00e8ncies negatives, amb menys plantes hi ha m\u00e9s sequeres i a l&#8217;inrev\u00e9s, i amb menys plantes fins i tot tindrem menys recursos per a la salut. Algunes d&#8217;aquestes q\u00fcestions ja s\u00f3n una realitat. Al Regne Unit s&#8217;ha multiplicat el cultiu de la vinya, impensable fa unes d\u00e8cades. I al Mediterrani les sequeres s\u00f3n m\u00e9s prolongades. La paradoxa negativa \u00e9s que, amb menys aigua, necessitarem m\u00e9s aigua per a regar. Els cereals tenen un major rang de temperatura per a aguantar, per\u00f2 la vinya \u00e9s molt m\u00e9s sensible a unes m\u00ednimes variacions. Una conseq\u00fc\u00e8ncia pot ser el canvi de les varietats actuals per altres m\u00e9s resistents als nous escenaris.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-3487\" src=\"https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/IMG20220309191057.jpg\" alt=\"\" width=\"1024\" height=\"768\" srcset=\"https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/IMG20220309191057.jpg 1024w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/IMG20220309191057-300x225.jpg 300w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/IMG20220309191057-768x576.jpg 768w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/IMG20220309191057-80x60.jpg 80w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/IMG20220309191057-265x198.jpg 265w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/IMG20220309191057-696x522.jpg 696w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/IMG20220309191057-560x420.jpg 560w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p>Al Mediterrani i en el tr\u00f2pic, amb m\u00e9s temperatura i menys precipitacions, les plantes estan produint menys fotos\u00edntesi que fa 30 anys. M\u00e9s o menys en el mateix per\u00edode, els inventaris forestals indiquen clar\u00edssimament una major taxa de mortalitat d&#8217;arbres a Europa i els Estats Units. En els \u00faltims cent anys s&#8217;han perdut unes 600 esp\u00e8cies de biodiversitat vegetal. Si no hi ha fre al canvi clim\u00e0tic, aquesta p\u00e8rdua s&#8217;accelerar\u00e0. Mentrestant, la poblaci\u00f3 humana continua creixent, substituint zones boscoses per agr\u00e0ries o urbanes. Estem robant territori a la vegetaci\u00f3. Amb menys biodiversitat vegetal, tot \u00e9s menys productiu i absorbim menys CO2.<\/p>\n<p style=\"text-align: justify;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-3483\" src=\"https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas8.jpg\" alt=\"\" width=\"1024\" height=\"683\" srcset=\"https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas8.jpg 1024w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas8-300x200.jpg 300w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas8-768x512.jpg 768w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas8-696x464.jpg 696w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas8-630x420.jpg 630w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/> <img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-3477\" src=\"https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas5.jpg\" alt=\"\" width=\"1024\" height=\"768\" srcset=\"https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas5.jpg 1024w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas5-300x225.jpg 300w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas5-768x576.jpg 768w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas5-80x60.jpg 80w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas5-265x198.jpg 265w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas5-696x522.jpg 696w, https:\/\/ramib.org\/oficial\/wp-content\/uploads\/2022\/03\/flexas5-560x420.jpg 560w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p style=\"text-align: justify;\">La pon\u00e8ncia va ser seguida amb gran inter\u00e8s pel p\u00fablic assistent finalitzant amb l&#8217;habitual debat posterior a les pon\u00e8ncies.<\/p>\n<p style=\"text-align: justify;\">Pot visualitzar la sessi\u00f3 cient\u00edfica en el canal de youtube de la corporaci\u00f3 seguint el seg\u00fcent enlla\u00e7:<\/p>\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Sabem com responen les plantes al canvi clim\u00e0tic i per qu\u00e8 ens hauria d&#039;importar?\" width=\"696\" height=\"392\" src=\"https:\/\/www.youtube.com\/embed\/Syn4oms7NoI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Sessi\u00f3 cient\u00edfica. &#8211; Dia 9 de mar\u00e7 es va celebrar en la seu acad\u00e8mica de Can Campaner la sessi\u00f3 cient\u00edfica \u201cSabem com responen les plantes al canvi clim\u00e0tic i per [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":3473,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[24,269,17],"tags":[279,278,277],"_links":{"self":[{"href":"https:\/\/ramib.org\/oficial\/index.php\/wp-json\/wp\/v2\/posts\/3442"}],"collection":[{"href":"https:\/\/ramib.org\/oficial\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ramib.org\/oficial\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ramib.org\/oficial\/index.php\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/ramib.org\/oficial\/index.php\/wp-json\/wp\/v2\/comments?post=3442"}],"version-history":[{"count":3,"href":"https:\/\/ramib.org\/oficial\/index.php\/wp-json\/wp\/v2\/posts\/3442\/revisions"}],"predecessor-version":[{"id":3491,"href":"https:\/\/ramib.org\/oficial\/index.php\/wp-json\/wp\/v2\/posts\/3442\/revisions\/3491"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ramib.org\/oficial\/index.php\/wp-json\/wp\/v2\/media\/3473"}],"wp:attachment":[{"href":"https:\/\/ramib.org\/oficial\/index.php\/wp-json\/wp\/v2\/media?parent=3442"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ramib.org\/oficial\/index.php\/wp-json\/wp\/v2\/categories?post=3442"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ramib.org\/oficial\/index.php\/wp-json\/wp\/v2\/tags?post=3442"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
