Oceans were hottest on record in 2019

Lijing Cheng, the paper's lead author and an associate professor at the International Center for Climate and Environmental Sciences at the Chinese Academy of Sciences, blamed this on humans.

Researchers say they are particularly concerned about the Southern Ocean warming and it's affects on the Antarctic Ice Shelves. Scientists say a similar situation has been experienced for several years, a new temperature record is broken every year, they say.

Since 1970, more than 90 percent of the planet's excess heat went into the oceans, while less than 4 percent was absorbed by the atmosphere and the land, the study said.

"When the Sun's energy reaches the Earth, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases such as carbon dioxide".

According to the study, the oceans are warming at an increasing speed and while the past decade has been the warmest on record for global ocean temperatures, the hottest five years ever recorded all came in the last five. The ocean has been the warmest in the past 10 years than it's been since measurements were first taken in the 1950s. Other than the human emissions of gases that trap heat, there are no sensible alternatives to explain this warming.

John ABRAHAM, co-author and professor of mechanical engineering at the University of St. Thomas in the United States, said, "It is critical to understand how fast things are changing".

"The key to answering this question lies in the oceans - this is where the vast majority of the heat ends".

According to the researchers, people can work to reverse their effect on the climate, but the ocean will take longer to respond than atmospheric and land environments.

Frequent avalanches and landslides occur in Kashmir during the winter, often blocking roads and leaving communities isolated. According to The News , 23-inch snowfall was recorded in parts of Chitral district including Lowari Tunnel.

The study found that average 2019 ocean temperatures were about 0.18 degrees Fahrenheit (0.075 degrees Celsius) above the average between 1981 and 2010.

The global team of 14 scientists from 11 institutes across the world, call for action to reverse climate change.

Hotter oceans also expand, leading to sea level rises.

The researchers used new analysis methods to measure ocean temperature from the surface to 2,000 meters deep. As the beaches are the main respiratory of the Earth's energy imbalance, estimating ocean heat content (OHC) is a standout amongst other approaches to measuring the pace of global warming.

In the period between 1987 and 2019, warming accelerated at nearly 4 1/2 times the rate observed in the period between 1955 and 1986, the report showed.

The North Pacific ocean heat wave "The Blob" was first discovered in 2013 and wreaked havoc until 2015.

"Fortunately, we can do something about it: We can use energy more wisely and we can diversify our energy sources". This amount of heat is spreading across the oceans of our planet.
