Sea Sponge Study Proves the Globe is Warming?

( – Researchers have been studying sea sponges outside of the Caribbean, and it may have proved that Earth is getting hotter and can even tell us by how much.

There has been a study of sea sponge temperatures over the past 300 years, and it has just proven that Earth has already risen by a temperature of 1.5º Celsius and that it’s continuing to increase. A paper that was published by Nature Climate Change on Monday said that we can expect to hit a 2º Celsius rise by the end of the decade.

Samples of these sea sponges were taken in the Caribbean, the reason being that there is less temperature diversity in this area compared to others. According to the temperatures taken from these sponges, there were consistent temperatures between 1700 to 1790 and then again from 1840 to 1860. The gap was described as a cooling in temperatures, which was said to be brought on by volcanic activity.

The climate started warming as a result of human activity around the 1860s and has continued from that point. By 1870 there was a clear indication of rising temperatures due to this.

These sea sponges are used because they can hold the chemical changes in their skeleton which is made of calcium carbonate and serves as a natural method for looking into ocean temperatures. The industrial era of warming has been deemed as 1.5º Celsius and it’s said that this has already been reached and that the ground warming was 1.7ºC, which could have occurred anywhere from 2018 to 2022.

Malcolm McCulloch, a professor of isotope geochemistry at the University of Western Australia and lead author of the study spoke out about the warming. He said, “Since then, the increasing global mean surface temperatures, which means global warming, has been half a degree greater than the currently accepted estimates.”
