The earth is at its most crucial temperature after 100,000 years. The Green Planet is seriously on the edge because of its condition.

Carol Snyder, part of U.S. Environmental Protection Agency, used her doctoral dissertation at Stanford University to create a continuous record of the Earth's temperature over the last two million years. This is huge news for science, as the previous compilation only contained records from the last 22,000 years.

The ratios of magnesium and calcium, acidity and species physique can determine the factors affecting the Earth's rising temperature. Also, Snyder studied the proposed temperature reconstruction on 61 different sea temperatures across the globe.

"These are rough estimates with large margins of errors," Snyder said. But later on, she discovered that temperature changes are directly affected by carbon dioxide (CO₂₎ in the atmosphere.

For the last 5,000 years, the gas emissions on the atmosphere has a high content of CO₂ and it is the main reason why Earth's temperature is raising two degrees Celsius hotter.

Snyder wanted to explain that if the factors affecting the climate is the same with the previous years, the Earth is facing another temperature raise of seven degrees Celsius. "This is based on what happened in the past," Snyder said. "In the past it wasn't humans messing with the atmosphere."

In a journal in Nature published last Sept. 26, Eelco Rohling, a palaeoclimatologist at the Australian National University said, "The key part of this paper is the temperature reconstruction, which is really valuable."

Scientists have praised Snyder's work. Jeremy Shakun of Boston College said, "Snyder's work is a great contribution and future work should build on it," though he called Snyder's temperature reconstruction unrealistic.

Climate change is worsening and if it does not stop, Earth will continue to experience hotter temperatures as the experts warn.
