NASA: Earth absorbs an "unprecedented" amount of heat

New ominous research shows that the Earth absorbs one "Unprecedented" amount of heat. In fact, the last 15 years, the amount of incoming solar radiation trapped on the surface and in the oceans has doubled. These are findings published in Geophysical Research Letters by its scientists NASA and the National Oceanic and Atmospheric Administration (NOAA).

Scientists explain that the Earth is just like humans - it has a budget. In other words, it absorbs energy from the sun and emits an equal and opposite amount of energy back into space, as if an average person were being paid, and then uses that money to pay bills. However, the Earth budget is becoming more and more "unbalanced".

NASA and NOAA scientists decided to study this energy imbalance, which today reaches only 0,3%, which means that the planet is currently absorbing more energy from the sun than it is emitting back into space. This action must do something here on Earth and the end result is general more heat. To assess how this imbalance has changed since 2005, researchers collected satellite data, looking at the top of the atmosphere and one autonomous float network collecting data at the top 6.561 feet (2.000 meters) of the ocean. The first data set shows what kind of energy comes and goes while secondly gives an idea of ​​where 90% of world heat is stored.

The results show a significant change - record over the last 15 years. Both data sets show that the planet has nearly doubled the amount of heat it has absorbed since 2005. The fact that both data sources give the same data confirms to researchers that we are dealing with a rather worrying trend.

Gregory Johnson, an oceanographer at NOAA's Pacific Marine Environmental Laboratory and author of the study, told the Washington Post: "It is a huge amount of energy. "It's such a difficult number to escape."

To give a clearer picture of the magnitude of the problem, Johnson explained that the heat absorbed by the Earth, equates to dropping four atomic bombs like the one that fell on Hiroshima, every second. He added that this increase in energy is equivalent to every person on earth using 20 electric tea kettles at the same time. The team should conduct further research to identify them factors that have led and continue to lead to this increase. However there are indications that its gas emissions are increasing greenhouse and the reduction of cloud cover and sea ice could be part of this, as well as cyclical changes in climate. One thing is for sure, Johnson said: "We are responsible for part of this problem."

In addition, Norman Loeb, a researcher at NASA's Langley Research Center, said in an email: "This study shows that the planet as a whole has been warming at an alarming rate over the last 15 years. We estimate that the heating will continue, but our hope is that the rate of heating will slow down in the coming decades ".

Although it is obvious to anyone who has lived on Earth for the last 15 years that energy imbalance has detrimental effects, this research helps quantification of the problem in strict terms. It also helps researchers analyze exactly what is happening in more detail, including how this could affect the global average. temperature, rising sea levels and other better known phenomena related to the climate crisis.

"Things that people are most interested in - such as rising global warming, rising sea levels, extreme weather, etc. - are all symptoms of energy imbalance, which in turn is a consequence of increases in greenhouse gases, such as carbon dioxide and methane ", underlined Loeb.

Reasonably, scientists are concerned that if the imbalance continues to increase, it could lead to even more dramatic effects in climate change earlier than expected.
