for better research go to under NOAA - Climate.gov
This is a short paraphrased summary of the article about ice cores in that website.
Answer: Researchers in labs may melt or crush bits of the ice core a little at a time, each deeper layer shows the time in the Earth's climate history. Tiny pieces of pollution, metals, radoiactive fallout, pebbles, sea salt, volcanic ash and even air bubbles all present important information that researchers can look for to track changes in the atmosphere's composition and temperature.

Answer:
Set of electromagnetic radiation.
Explanation:
The electromagnetic spectrum is the energetic distribution of the set of electromagnetic radiation. It consists of <u>electromagnetic waves</u>, which are composed by an electric field and a magnetic field. Every object emits and absorbs these kinds of radiations. This spectrum encompasses from Gamma rays, which are highly energetic electromagnetic waves with high frequency and short wavelength, to Radio waves, which are low energetic electromagnetic waves with low frequency and long wavelength. The visible light, like the sunlight, is only a tiny portion of the electromagnetic spectrum, the rest of the electromagnetic waves are invisible to the human eye, like infrared light, UV light, X-rays, and microwaves, but they can be perceived and be measured with proper filters.
Answer:

people making mistakes or being
equipment breaking down
natural disasters such as hurricanes, storm surge or high winds
deliberate acts by terrorists, acts of war, vandals or illegal dumping.
