Scientists have identified the past changes in the climatic conditions that occurred because of the following reasons. These includes:

Milankovitch cycles: These cycles are related with the orbit motion and tilt of the earth that occur in every 100,000 years, believed to be responsible for the past ice ages. The formation of the ice age is likely to affect the past climatic conditions.

Thermohaline circulation: It is the circulation of water which influences the temperature and salt content of the water body or a terrestrial land.

Plate tectonics and volcanic activity: The plate tectonics is related with the splitting apart or movement of the large continental and oceanic plates over the surface of the lithosphere. It is related with the intense seismic activity that is occurrence of earthquakes and eruption of volcanoes. The volcanoes could have influenced the climatic conditions in the past. The release of the dust particles and gases thrown into the atmosphere due to the eruption being added up with the atmosphere may either heat up the surrounding air or may cause cooling.

type 2 happens when excess consumption of high-sugar foods flood the blood supply with glucose and reduce the production and effectiveness of insulin. if a person has prediabetes, they can reduce the risk of full diabetes through regular exercise and a balanced, low-sugar diet.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
