The ocean is heating up 4 times faster

The researchers discovered that the ocean is heating up at a faster speed. The study published on January 28 in Environmental Research Letters showed that the warming of the ocean has increased more than 4 times over the past 40 years and may increase faster in the future. The heating rate of sea surface temperature has increased from 0.06 degrees Celsius per decade in the 1980s to 0.27 degrees Celsius per decade.

The model’s model shows that this level of heat will occur again in the next two decades and accelerate more if people do not solve the causes of climate change and stop using fuel. jelly.

Dr. Christopher Merchant, a professor about Ocean and Earth’s observation at Reading University, England, the main author of the study, said the ocean usually decides the global heating speed because they are the main thermal tank of the fruit. Soil and heat absorption from the atmosphere. This means that if the warming of the ocean is fast, it is a sign that climate change is also accelerating. “The current trend shows that the world is heating up faster than what we have experienced,” Merchant said. “That means all the impacts are coming to us faster.”

The global warming causes rising sea levels, threatening coastal communities, causing more severe weather and arguing soil, affecting the ability to growing food. Scientists have warned that uncontrolled climate change will bring unmistakable sufferings to billions of people, and cause part -thirds of species on Earth to be extinct.

Merchant and colleagues have used satellite data to model changes in the global average marine surface temperature for decades. The team has found an increasing heating trend along with natural changes caused by phenomena like El Niño.

The team has linked the rapid warming of the ocean with climate change and the Earth’s absorption of more energy than it emits – a phenomenon called the Earth’s energy imbalance. Greenhouse gases such as carbon dioxide (CO₂) and methane (CH4) retain heat in the atmosphere, heat the planet and then the oceans. This process, along with other human activities and natural changes, is the main cause of the Earth’s energy imbalance, this phenomenon has doubled in the past two decades.

Merchant noted that the trend of the ocean has increased rapidly in the past 15 years because the earth is absorbing more sunlight as well as the heat was retained by the greenhouse gases. The researchers believe that this increasing absorption of sunlight is associated with reducing the coverage of clouds, meaning that more sunlight through the earth is more. The global warming also reduces the snow and ice that can reflect sunlights back to the space.

The authors noted that the heat of the ocean surface and globally in the past four decades showed that it would heat more if the climate change was not successful. “If we want to stabilize the climate, we need to make more efforts to provide our lifestyle without fossil fuel,” Merchant said. “Good news is a significant conversion that is happening all over the world.”
