It's AN increase IN THE average temperature of oceans and the Earth's atmosphere. Greenhouse effect is caused BY THE release (gazy cieplarniane) to atmosphere especially dioxide and methane. (Gazy cieplarniane) don't let infrared radiation get out from earth to space.
'It' THIS causeS THE 'warm up earth' (zla kol slow - earth to warm up). The reason 'of' FOR global warming is humans' activity.
All 'of this activity' (napisz...THESE ACTIVITIES damage nature. One of
the biggest reason of greenhouse effect is deforestation, because
trees clear air from dioxide. You can think that raising THE temperature about A couple of degreeS (couple znaczy wiecewj jak jeden) 'don't' (prosze pisac w calosci i wtedy nie bedziesz robil glupich bledow tutaj WILL NOT) affect 'on' THE climate.
It's not true, because higher temperature will change many things in
THE environment. 'There's' HERTE ARE the most important results.
Rising oceans level from 9 to 88 'centimeters' (ortog)' . 'It' THIS can cause flood or totally 'zalanie (wodą)' (to jest w slowniku) some areas like Florida or the Netherlands.
Secondly, unusual droughts and 'heats' HEATWAVES 'which' (niepotr) will cause shortage of water, fires and THE death OF thousands of people. ParadoxicalLY in some areas THERE can occur A storm or AN unusual rainfall. (Prosze sie nauczyc gdzie stosujemy 'a', 'an, i 'the' bo to mnie juz zaczyna wk....)
Extinction of many species of animals and plants which 'won't' WILL NOT be able
to adapt to new conditions.
And the last, but not least thing is THE risk OF illness transmission by
insects and rodents in countries where this illness HAD NOT 'didn't' PREVIOUSLY occurRED.
To sum IT up global warming is A big danger for all people, animals and
plantS living 'in' ON our planet.
