It is quite an understatement to say that the topic of climate change is controversial. At least half of the global population believe that climate change is just a propaganda that benefits the upper one percent. The other half believe that climate change is not only real but also the consequences of the damages man has inflicted Mother Earth.

When one thinks of climate change, global warming is not far off. In fact, a study has recently debunked one of the theories regarding global warming. The study found that the so-called Tropical Thermostat Theory is a lie and global warming will most likely kill off the tropical biospheres.

According to the recent climate-based and geological study conducted by Professor Matthew Huber of the Purdue University, there is evidence found that disproves the Tropical Thermostat Theory. Moreover, the study found that as temperatures rise due to global warming, the tropics will most likely be also affected and warming could possible kill off almost all of the tropical biospheres.

Dating as far back as the 1980's, there have been numerous theories suggesting that when the planet experiences rising temperature, the temperature at the tropics would most likely be strictly limited and regulated by a tropical internal thermostat. This so-called thermostat protects the biodiversity in the tropics from the rising temperatures.

However, the recent study, published in the journal Science Advances, found evidence that invalidates the Tropical Thermostat Theory. According to the Professor Huber, 56 million years ago, the planet experienced extremely hot global temperatures that lead to the annihilation of some of the tropical biospheres of Earth.

In fact, the analysis of the Paleocene-Eocene Thermal Maximum (PETM) time period provides evidence that the planet experienced such high temperatures. The Paleocene-Eocene Thermal Maximum period is said to be the warmest period the planet experienced for the past hundred years.

To be accurate, data has shown that during the PETM, the global temperatures rose rapidly five degrees Celsius higher while the tropics experienced a rapid increase of temperatures by 3 degrees Celsius. This 3-degree increase in temperature leads to the dying of some of the tropical biospheres.

These findings are the very first detailed information obtained that demonstrated key changes involving global warming and the tropics. Due in thanks to the analysis of biotic records taken from a Nigerian deposit of shallow marine sedimentary.

In particular, the analysis of the carbon isotopes found in shells and deep sea sediments left behind help indicate pinpoint the changes of temperature during PETM and other conditions that lead to the death of some of the living organisms due to global warming.

Focusing on climate modeling using the data collected, Professor Huber reports that if there were no tropical thermostat present, global warming could eradicate tropical biospheres. This is quite alarming as most of the planet's biodiversity and human population reside in the Earth's tropics. And what's worse is that due to rising global temperatures, it is not too far off to happen during this lifetime.
