Answer:
Tina can examine and investigate weather patterns from further back than 150 years using climate proxies.
Climate proxies are preserved physical characteristics of the past that stand in for direct meteorological measurements and enable scientists to reconstruct the climatic conditions over a longer fraction of the Earth's history. Reliable global records of climate starts in 1880s, and proxies provide the only means for scientists to determine climatic patterns before record-keeping began.
Explanation:
Examples of proxies include ice cores, tree rings, sub-fossil pollen, boreholes, corals, lake and ocean sediments, and carbonate speleothems.
The characteristic of this deposition or rate of growth of the proxies' material mentioned has been influenced by the climatic conditions of the time in which they were laid down or grew.
Some of this proxies, such as gas bubbles trapped in ice, enable scientist to recovered traces of the ancient atmosphere and measured directly to provide a history of fluctuations in the composition of the Earth's atmosphere.
To come up with precise results, systematic cross-verification between proxy indicators is necessary for accuracy in readings and record-keeping.
