Klimunist\u00e9 op\u011bt zneu\u017e\u00edvaj\u00ed sou\u010dasn\u00fdch veder k tomu, aby prosadili \u201eklimatick\u00e1\u201c omezov\u00e1n\u00ed na\u0161\u00ed svobody a \u201euhl\u00edkov\u00e9\u201c tah\u00e1n\u00ed pen\u011bz z na\u0161ich kapes.<\/span><\/strong><\/p>\n

Jen\u017ee i kdybychom se tu ugr\u00fdnd\u00fdlovali k \u00fapln\u00e9 chudob\u011b (co\u017e je ostatn\u011b c\u00edlem EU), klima t\u00edm nezm\u011bn\u00edme a vedra nezastav\u00edme. Jen na tom zbohatne p\u00e1r vychytr\u00e1lk\u016f.<\/p>\n

Je tu ale zp\u016fsob, jak m\u016f\u017eeme citeln\u011b zm\u00edrnit dopad veder a zajistit, aby i v l\u00e9t\u011b bylo ve m\u011bstech p\u0159\u00edjemn\u011b. T\u00edmto \u201ez\u00e1zrakem\u201c jsou vzrostl\u00e9 stromy, kter\u00e9 v\u00fdznamn\u011b ochlazuj\u00ed sv\u00e9 okol\u00ed.<\/p>\n

Ono je to uk\u00e1zkov\u011b vid\u011bt u n\u00e1s v Rokycanech. Jist\u00e1 sv\u00e9r\u00e1zn\u00e1 \u00fa\u0159ednice zde soustavn\u011b likviduje hodnotn\u00e9 stromy, a kdy\u017e u\u017e v\u016fbec n\u011bco vys\u00e1z\u00ed, tak cizokrajn\u00e1 ko\u0161\u0165ata, kter\u00e1 zde nep\u0159e\u017eij\u00ed. D\u016fsledek c\u00edt\u00edme na vlastn\u00ed k\u016f\u017ei: Jak ub\u00fdv\u00e1 zelen\u011b, tak se na\u0161e m\u011bsto st\u00e1le v\u00edce p\u0159eh\u0159\u00edv\u00e1 a sni\u017euje se zde kvalita \u017eivota.<\/p>\n

Zele\u0148 toti\u017e funguje jako p\u0159irozen\u00e1 \u201eklimatizace\u201c. Nejen\u017ee vrh\u00e1 st\u00edn, ale nav\u00edc odpa\u0159uje vodu, \u010d\u00edm\u017e ochlazuje okol\u00ed. Litr odpa\u0159uj\u00edc\u00ed se vody spot\u0159ebuje 0,63 kWh energie (proto je v\u00e1m zima, kdy\u017e vyjdete ze sprchy). Vzrostl\u00fd strom m\u016f\u017ee odpa\u0159it i 200 litr\u016f vody za den a funguje t\u00edm jako \u201eklimatiza\u010dn\u00ed jednotka\u201c, kter\u00e1 odeb\u00edr\u00e1 z okol\u00ed teplo na odpar vody. V\u00fdkon t\u00e9to \u201eklimatizace\u201c m\u016f\u017ee \u010dinit u jednoho stromu i 15 kW.<\/p>\n

D\u00edky tomu se na zelen\u00fdch ploch\u00e1ch uvoln\u00ed mnohem m\u00e9n\u011b tepla ne\u017e na betonu. Tento rozd\u00edl m\u016f\u017ee \u010dinit i v\u00edce ne\u017e 500 W\/m2 (pro srovn\u00e1n\u00ed: otepluj\u00edc\u00ed vliv CO2 se odhaduje okolo 1 W\/m2). A pr\u00e1v\u011b to je p\u0159\u00ed\u010dinou toho, pro\u010d se m\u011bsta (ale i zem\u011bd\u011blsk\u00e1 krajina) tak p\u0159eh\u0159\u00edvaj\u00ed. 1 km2 hol\u00e9 plochy (beton, asfalt, hol\u00e9 pole, ale i fotovoltaika) vyd\u00e1v\u00e1 okolo 700 MW tepla, co\u017e je srovnateln\u00e9 s v\u00fdkonem vek\u00e9 uheln\u00e9 eletktr\u00e1rny \u010di poloviny temel\u00ednsk\u00e9ho bloku. U\u017e ch\u00e1pete, z \u010deho vznikaj\u00ed ta vedra?<\/p>\n

A klimunist\u00e9 to je\u0161t\u011b zhor\u0161uj\u00ed, kdy\u017e v\u0161ude vnucuj\u00ed fotovoltaiku a hl\u00e1saj\u00ed, \u017ee m\u00e1me omezit chov dobytka a t\u00edm nam\u00edsto pastvin a jetelovin (kter\u00e9 jsou cel\u00fd rok zelen\u00e9 a v l\u00e9t\u011b ochlazuj\u00ed) vys\u00edt nap\u0159. \u0159epku \u010di kuku\u0159ici, u nich\u017e je po \u010d\u00e1st vegeta\u010dn\u00ed doby hol\u00e1 p\u016fda, kter\u00e1 se p\u0159eh\u0159\u00edv\u00e1.<\/p>\n

Proto \u0159\u00edk\u00e1m: Pokud chceme \u0159e\u0161it vedra, vyka\u0161leme se Green Deal a \u201eklimatickou\u201c politiku a ozele\u0148me na\u0161e m\u011bsta a krajinu. Vra\u0165me do krajiny pastviny, jeteloviny a rem\u00edzky. Odstra\u0148me z pol\u00ed fotovoltaiku. Zastavme betonov\u00e1n\u00ed na\u0161\u00ed krajiny. A zejm\u00e9na: Bojujme za hodnotn\u00e9 stromy ve m\u011bstech a bra\u0148me se proti jejich k\u00e1cen\u00ed. To je ten \u201espr\u00e1vn\u00fd\u201c eko-aktivismus, kter\u00fd d\u00e1v\u00e1 smysl. Na rozd\u00edl od Green Dealu a \u201edekarbonizace\u201c.<\/p>\n
