Accurate evidence for the theory that Earth's climate has changed over geologic time includes data from ice cores, which reveal temperature fluctuations and atmospheric composition over hundreds of thousands of years. Sediment layers and fossil records indicate shifts in flora and fauna corresponding to past climate conditions. Additionally, isotopic analysis of marine sediments provides insights into historical ocean temperatures and ice volume changes. These lines of evidence collectively demonstrate the dynamic nature of Earth's climate throughout its history.
A palaeoclimate is the climate of the Earth at a specified point in geologic time.
The fossil evidence shows that the Earth's climate before had high levels of carbon dioxide. The plants that evolved consumed this carbon dioxide out of the air and formed oxygen, coal, limestone, and other fuels.
No. The 2004 tsunami was a geologic event unrelated to weather or climate.
Fossils tell how Earth's landforms, climate, and ecosystems have changed over time. They provide valuable clues about the past by preserving evidence of ancient organisms and environments.
Geological evidence refers to physical evidence found in rocks, minerals, landforms, and fossils that provide insights into Earth's history, past environments, and processes. This evidence helps scientists understand how the Earth has evolved over time and provides clues about past climate, tectonic events, and life on Earth.
Ice blanketed much of North America, northern Europe, and northern Asia at one time. That is pretty good evidence of a dramatic change in climate. There have been numerous ice ages, as revealed by rock strata and oxygen isotope ratios. Fossil evidence of rainforest organisms buried in what is now desert also reveal substantial changes in climate over geologic time.
Fossil evidence: identical fossils of plant and animal species have been found on continents that are now separated by oceans. Geologic evidence: similar rock formations and mountain ranges are found on opposite sides of different continents. Climate evidence: ancient climate patterns inferred from glacier deposits and coal deposits match up when continents are repositioned together as Pangaea.
There are fossils of tropical rainforest plants in areas that are now dry desert. Either the land has moved (which has also happened), or the climate changed. This is one of the most obvious bits of evidence for past climate change, but there are numerous others.
The area used to have ample water and a river to irrigate crops. When the climate changed, many people moved. There is other evidence to show that there were some violent times and there was evidence that a significant number of people had leprosy.

Geo-Strata not only occur in Earth, they are equally applicable in Ice Cores.
The Sahara Desert is balancing the climate that exists in other parts of Africa. In the geologic past, parts of the desert had a wetter climate.
The best evidence you have of past climate is written almanacs and weather reports. Almanacs have been kept for centuries and well document the climate.

No. The 2004 tsunami was a geologic event unrelated to weather or climate.
The earthquake didn't change climate.
