Answer:
<u><em>The answer is</em></u>: <u>Increase in the temperatures of planet earth.</u>
Explanation:
Climate change <em>is a significant and enduring change in the statistical distribution of weather patterns during periods ranging from decades to millions of years.
</em>
Global warming responds to an unequivocal and continuous increase in the average temperature of the Earth's climate system.
Climate change is changing our economy, health and communities in different ways. <em>Scientists warn that if we don't put the brake on climate change substantially now, the results are likely to be disastrous.
</em>
<em><u>If the Earth warms up, any of these important changes will occur:</u></em>
1.- The water expands <em>when it is heated and the oceans absorb more heat than the earth, the sea level will rise.
</em>
2.- The sea level <em>will also increase due to the melting of glaciers and sea ice.
</em>
3.- The cities of the coast <em>would suffer floods.
</em>
4.- Places where it normally rains or snows a lot <em>could get hot and dry.
</em>
5.- Lakes and rivers<em> could dry up.
</em>
6.- There would be more droughts<em> so it would be harder to grow corn.
</em>
7.- There would be less water <em>available for agriculture, food production, drinking or showering.
</em>
8.- Many plants and animals <em>would become extinct. </em>
9.- Hurricanes, tornadoes and storms <em>produced by changes in temperature and evaporation of water would occur more regularly.</em>
<u><em>The answer is</em></u>: <u>Increase in the temperatures of planet earth.</u>
