Of course we do mom.. Climate change includes both the global warming driven by human emissions of greenhouse gases, and the resulting large-scale shifts in weather pattern
And examples of it would be coal usage! Coal and gas pollutes the air!
And scientist have found out about past climates by looking at ice and the air bubbles in it.
Milankovitch cycles describe the collective effects of changes in the Earth's movements on its climate over thousands of years too, correct?
Yes! And Volcanic activity ranges from the emission of gases and lava! A volcanic event occurs when there is a sudden or continuing release of energy caused by near-surface or surface magma movement.
And an ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences!
