Will the havoc of summer break again

Will the havoc of summer break again?

Coming in terms of global warming is going to increase the concern. This is because of El Nino, which is coming by the end of this year. Here large parts of the world’s oceans are warm and have become unusually warm. This year’s heat may break records. Since mid-March, the global average sea surface temperature has reached more than 21 °C. Which is the highest temperature ever recorded. Meteorologists are worried about the news of the upcoming El Nino.

from the mouth of scientists

See what the meteorologists say, what is going on? The big picture of climate change is before us. Nine-tenths of all the heat trapped by greenhouse gases goes into the oceans. But there’s also an immediate reason: The rare triple-dip La Niña is over. During La Nina, cold water from the depths of the ocean rises to the surface. It’s like the air conditioner of the Pacific Ocean is on. But now the air conditioner has stopped. It is likely that we are bracing for El Niño, which brings hot, dry weather to Australia. And, according to NOAA, El Niño means areas of North America and Canada are drier and warmer than normal. But along the US Gulf Coast and Southeast, these periods are wetter than normal and also bring an increase in flooding.

La Nina is a masked heat

In the words of scientists, when you run your air conditioner, you are masking the heat outside. It’s the same for our oceans. La Nina brought cold conditions for three years. But the surprising thing is that despite this global warming continued rapidly. Now we can see summer thundering again. If El Niño develops, climatologists estimate that it could increase global temperatures by an additional 0.36 F (0.2 C).

El nino is coming soon

Wind patterns are beginning to change in the eastern Pacific near Chile. These winds prevent the rise of deep cold water from cooling the surface. That’s why the region can see much higher than average temperatures. This is often the start of an El Niño cycle, which typically brings dry and hot summer weather to Australia. It damages fisheries in Ecuador and Peru and brings torrential rains to parts of South America. Here in the middle of climate change, the centuries-old El Niño-Southern Oscillation is making its way and it is warming so much in the world’s oceans.

Why do oceans matter so much?

Along with atmospheric convection, ocean currents are the major carriers of heat around the globe. The sun does not radiate heat everywhere at the same rate. At the poles it is easier to see sunlight away, which is why they are colder. But the equator receives the full power of the Sun, heating the air and water. Ocean and air currents carry this heat towards the poles. As the currents move south, the heat is mixed with the surrounding water. The East Australian Current carries warm water from the tropics southwards, distributing the heat along south-eastern Australia. By the time the current reaches Hobart, it is usually much colder. Water can hold much more heat than air. In fact, just a few meters of the top of the ocean store as much heat as Earth’s entire atmosphere. The oceans are slow and cool only slowly. In contrast, the temperature of the surface’s atmosphere heats up very quickly and can cool down just as quickly.

How much energy in the oceans?

A startling study shows that around 380 zetajoules of excess heat was trapped on Earth from 1971-2020, 90% of which was taken by the oceans. This is a really huge number, equivalent to 25 billion nuclear bombs. Research has found warm currents – where heat is concentrated – that are pushing it south towards Antarctica.
