I'm going to talk about (the effects of) how global warming will change the way we live in the future.
Firstly, global warming is connectED with (przedimek) 'increasing' INCREASE IN the average temperature of the Earth's atmosphere. That is because of 'realeasing' (ortog) 'greenhouse's' GREENHOUSE gases to the atmosphere which are 'making' MADE by us, the humans.
I think THAT 'the' (niepotr) global warming is not the most 'dangerous danger' (poszukaj jakies inne slowo, bo tylko 'danger' danger') at all, but in fact, in the last 100 years, (przedimek) Earth's average surface temperature HAS increased by about 0,8C. Well, even 'slightly' (zla czesc mowy, tutaj SLIGHT) climate change CAN lead to enormous disasters.
To start WITH, global warming may cause (przedimek) melting of glaciers, (and consequently) 'as a result' (niepotr) the water level will rise and cities located near the coasts will be flooded.
Next, 'a lot of' (staraj sie uzywac 'wyzsze;' okreslenie jak 'a lot of' np. numerous) animals will become extinct, because there will be no place to live for them.
What's more, if we don't stop 'to produce' (inaczej, the production of) greenhousE gases we will observe more examples of 'extremes in the weather' (daj 'extreme weather'), such as blizzards, heatwaves or downpours, which may lead to floods, droughts or forest fires.
It also will lead to 'multiply' (inaczej, 'the multiplication') OF viruses and bacteria that will evolve and create 'a' (nie, bo mowisz o 2 rzeczach, virus i bacteria) new kindS of illnesses.
'Therefore' (nie, to nie pasuje tutaj, daj...As a precaution) people will definitely escape to different places to protect themselves and their families, but the question is: Will 'be' (niepotr) somewhere ELSE BE A good place to live?
To sum IT ALL up, global warming will certainly change the way we live in the future.
