The meaning of climate is a area's general pattern of atmospheric or weather conditions measured over long periods of time ranging from decades to thousands of years.
Different climates of the past are ice ages. The ice age began 2.4 millon years ago and lasted until 11,500 years ago. The earth's climate changed a lot between very cold periods.
How do geologists/scientists find out about past climates?
Geologists/scientists find out about past climates by using tree rings and ice cores. The difference between a thick and thin ice core is that the thick ice core means more participation and the thin one is less precipitation.
Milankovich cycle is the orbit shape of the earth and the orbit shape becomes a oval every 100,000 years and since the earth is farther from the sun , the climate becomes cold.
When a volcano erupts , ash comes out of it and makes the sky become cloudy. The earth becomes colder because the sun/sky is blocked by the ash
Ocean currents impact earth's climate when tectonic plates move which changes the ocean current. The ocean currents are able to affect weather and climate so when it changes , it becomes more cold or hot.
