What is the reason for the 54 increase in the number of marine heatwaves?

The earth's climate change makes you unimaginable, high temperature, low temperature, hot and cold may make us begin to adapt to this change, according to the University of New South Wales in Australia scientific research findings, our earth will appear hotter, longer, more frequent marine heat waves, this trend is constantly accelerating, human beings really can't escape, should come or come?

New scientific research shows that our terrestrial heatwaves are increasing, and that global marine heatwaves have lasted longer, are more numerous and increase in intensity over the past century. More data shows that the global heatwave has accelerated significantly since 1982, so it is getting hotter and hotter every year.

Canadian scientist Eric said that from 1925 to 2016, studies found that the frequency of marine heatwaves increased by an average of 34 and the duration of each heat wave increased by 17 per hour. This has led to an increase of 54 per year in the number of marine heatwave days. The onslaught of these heat waves has led to significant impacts on biodiversity, economic production.

According to historical statistics, the 2011 heat wave led to seaweed flooding in Australia's oceans. In 2012, a marine heatwave in the Gulf of Maine led to an increase in lobsters. The 2014-2016 heatwave led to the closure of fisheries in the North Pacific, illustrating the severity of the consequences of the heatwave and even altering large-scale weather patterns in the Northwest Pacific.

In 2016, Tasmania experienced a disease outbreak due to a marine heatwave, which explains the ongoing heatwave. Satellite data have eliminated the effects of natural variability caused by the El Niño Southern Oscillation, the Pacific Decade-in Oscillation and the Multi-Decole Oscillation in the Atlantic Ocean to identify underlying trends with a clear relationship between the increase in global mean sea surface temperature and the increase in marine heatwaves.

Science professor Holbrook said the pattern was very similar to extreme weather events caused by rising global temperatures. **Marine heatwaves are likely to continue to increase. Such a heat wave will bring a new round of damage to the planet.

In the past few days, the weather in our country has also changed generally, a few days of hot and a few days of cold, and everyone is almost unbearable, so it may also indicate that our climate pattern has indeed changed.

The main reason is that the close human activities have led to global warming, the marine environment has also been damaged, and the marine heat wave has been increasing.

In fact, the 54% increase in the number of marine heatwaves is due to human deforestation, which leads to the destruction of nature, the excretion of pollutants, and the global warming.

The reasons for the increase in the number of marine heat waves are as follows: (1) the increase in global temperature is directly related to the increase in marine heat; (2) The destruction of the ecological environment by humans has exacerbated the number of marine heat waves.

Marine heatwave refers to a marine disaster in which the water temperature in the sea area is abnormally high, the ocean temperature rises, and lasts for an extremely long time.

The damage to the marine ecosystem is very direct due to the marine heatwave, which will not only cause the zooxanthellae to leave the coral, resulting in coral bleaching and death, but also affect the fish for a long time, which will eventually lead to the escape or death of a large area of fish, and eventually lead to marine desertification.

Marine heatwaves can cause drastic changes in the ocean system, as ocean "residents" find that the surrounding waters are warmer than fish are accustomed to. Much of the previous research in this area has focused on the local effects of such events on species such as corals, without taking into account the fact that they can autonomously seek out migratory organisms (e.g., fish) that prefer their environment.

Solutions to marine heatwaves

1. Since more than 90% of the heat comes from humans, causing global warming to enter the ocean, it is likely that the leakage of marine heat waves will continue to increase. In the face of the ocean's call for distress, the solution is to stop global warming and climate change.

2. If you really want to mitigate the effects of these marine heatwaves, you need to reduce greenhouse gas emissions and move away from a carbon-based economy. In this regard, we should accurately quantify the amount of changes we have made to the marine ecosystem, and strive to improve the overall situation of environmental protection and green for the whole person.

3. Protect the environment, take care of the environment, and start from the small things around you.

On August 15, 2018, a climate change report published in the British journal Nature said that analysis of large-scale data and global earth system models showed that global warming could lead to more frequent, more intense and more widespread marine heatwaves. The researchers noted that between 1982 and 2016, the number of days of marine heatwaves doubled.

Marine heatwaves, which are prolonged periods of unusually high temperatures on the surface of the ocean, can have serious consequences, such as the catastrophic death of corals on Australia's Great Barrier Reef after an extreme marine heatwave in 2016; The 2014-2016 marine heatwave led to the closure of fisheries in the North Pacific. In addition to causing disease outbreaks and declining growth rates in aquaculture, it can even alter large-scale weather patterns.

Thomas Florischer, a researcher at the University of Bern in Switzerland, and his colleagues analyzed and assessed the past and future trends of marine heatwave characteristics. The research team cited global average daily sea surface temperature data from 1982 to 2016 and 12 global Earth system models from 1861 to 2100 to show that continued global warming will lead to more frequent, wider, more intense and longer duration of ocean heatwaves.

Based on the current carbon reduction policies of various countries, by the end of the 21st century, the global temperature is likely to rise relative to pre-industrial levels, and in this case, the average probability of marine heatwaves will be 41 times that of pre-industrial water levels. On average, the spatial amplitude of a heatwave will increase 21-fold, the duration will reach 112 days, and the maximum intensity will increase.

Still, the researchers point out that these increases would be reduced if global warming were kept to or below by the end of the 21st century, with only a 40% chance of marine heatwaves under a warming scenario.
