Aquesta passada setmana (del 13\/11 al 19\/11) a primer curs d’ESO i dins de la mat\u00e8ria de medi natural (Biologia i Geologia) hem treballat el canvi clim\u00e0tic, aix\u00ed com les seves causes i conseq\u00fc\u00e8ncies.<\/p>\n

L’augment de les emissions de gasos d’efecte hivernacle, principalment de di\u00f2xid de carboni (CO2), com tamb\u00e9 de met\u00e0 (CH4), d’\u00f2xid nitr\u00f3s (N2O) i de hidrofluorocarbonats (HFCs) s\u00f3n els causants d’aquest efecte i en conseq\u00fc\u00e8ncia de l’escalfament global.<\/p>\n

L’efecte hivernacle es produeix, quan la pres\u00e8ncia d’aquest gasos a l’atmosfera impedeix la sortida\u00a0 a l’espai exterior, de les radiacions calor\u00edfiques procedents del Sol que han estat reflectides per la superf\u00edcie terrestre. D’aquesta manera, a causa de la quantitat cada vegada m\u00e9s gran de radiacions atrapades, augmenta tamb\u00e9 la temperatura mitjana de la Terra. Aquest augment de la temperatura del nostre planeta es coneix amb el nom d’escalfament global.<\/p>\n

Els seus efectes poden ser devastadors, fusi\u00f3 dels casquets polars, augment del nivell del mar, inundaci\u00f3 de les zones costaneres, disminuci\u00f3 d’aigua dol\u00e7a, migraci\u00f3 massiva de part de la poblaci\u00f3, conflictes, guerres, canvi clim\u00e0tic, sequeres, disminuci\u00f3 de collites, inundacions, increment dels danys produ\u00efts per fen\u00f2mens meteorol\u00f2gics de gran magnitud, disminuci\u00f3 de la biodiversitat per desaparici\u00f3 d’algunes esp\u00e8cies, augment de malalties parasit\u00e0ries, etc.<\/p>\n

Per aquest motiu i per tal de minimitzar els impactes ocasionats per aquestes emissions contaminats, s’han proposat a classe, un seguit de mesures que podem realitzar de forma tant col\u00b7lectivament, com individualment. Algunes d’aquestes mesures convindria refor\u00e7ar-les a casa, en l’\u00e0mbit de les fam\u00edlies, per tal que l’alumnat en prengui consci\u00e8ncia i sobretot l’h\u00e0bit de dur-les a terme. De ben segur que d’aquesta manera, amb la pr\u00e0ctica de la regla de les tres R, entre tots farem un m\u00f3n millor.<\/p>\n

Us deixo un enlla\u00e7 com a recordatori d’algunes mesures que podeu practicar,\u00a0 aix\u00ed com d’altres enlla\u00e7os d’inter\u00e8s.<\/p>\n
