Answer 1

Evidence of climate changes and conditions that affected early societies are gathered from Ice Core

EXPLANATION:

• A high-mountain glacier or an ice sheet has an ice core. Because the ice forms from the rise in annual snow levels, the lower layers are older than upper layers and the ice core includes ice which has been formed over a number of years. Ice cores give us a lot of knowledge besides ice gas bubbles.
• Melt surfaces, for example, are connected to the season. Further melting layers indicate hotter summer temperatures in the atmosphere. When the surface snow melts, melting layers are formed, releasing waters into the snowpack. Ice cores are a huge record of high resolution that enables us to take a look at global and hemispheric climate change.
• Ice encompasses volcanic eruptions’ dust and desert windstorms, microbes, pollen, small trapped bubbles of fossil air, meteorites, variations in the concentrations of Beryllium-10, indicating changes in the strength of solar radiation. All these details combine to provide scientific researchers with a surprisingly detailed history of last seasons and can be used for the reconstruction of a continuous and accurate climate record over hundreds of thousands of years.  

To know more

When analyzing the ice core, scientists discovered that the carbon dioxide (CO2) levels in the atmosphere were much lower than they are now. Since CO2 is a greenhouse gas, what does the lower CO2 level in the past say about our current climate?
