What has resulted in significant climate changes.

The answer is: Increase in the temperatures of planet earth.

Explanation:

Climate change is a significant and enduring change in the statistical distribution of weather patterns during periods ranging from decades to millions of years.

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. Scientists warn that if we don't put the brake on climate change substantially now, the results are likely to be disastrous.

If the Earth warms up, any of these important changes will occur:

1.- The water expands when it is heated and the oceans absorb more heat than the earth, the sea level will rise.

2.- The sea level will also increase due to the melting of glaciers and sea ice.

3.- The cities of the coast would suffer floods.

4.- Places where it normally rains or snows a lot could get hot and dry.

5.- Lakes and rivers could dry up.

6.- There would be more droughts so it would be harder to grow corn.

7.- There would be less water available for agriculture, food production, drinking or showering.

8.- Many plants and animals would become extinct.  

9.- Hurricanes, tornadoes and storms produced by changes in temperature and evaporation of water would occur more regularly.

The answer is: Increase in the temperatures of planet earth.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
