Abychom zm\u00edrnili zm\u011bnu klimatu, mus\u00edme p\u0159ej\u00edt na obnoviteln\u00e9 zdroje energie, jako je sol\u00e1rn\u00ed a v\u011btrn\u00e1 energie, kter\u00e9 neprodukuj\u00ed sklen\u00edkov\u00e9 plyny.

Abychom udr\u017eeli glob\u00e1ln\u00ed teploty pod hranic\u00ed 2 \u00b0C, mus\u00edme drasticky sn\u00ed\u017eit emise sklen\u00edkov\u00fdch plyn\u016f.
