Why don’t people believe in climate change?

Someone said in one of the good posts here:

When a world two or three degrees warmer is really as bad as is spread by certain alarmists….

why not stand on the brakes rigorously?

In response to the conditions of the oceans, warming and the very close consequences, I have allowed myself to give a striking example of why 2 degrees is a real disaster and hope to stimulate thinking.

“I don’t know if you’re a diver or any other well-founded knowledge of our oceans, but I, as a professional diver who spends almost as much time in the water as on land, can report from my own experience that you can virtually watch the seas die Can.

This is due, on the one hand, to the excessive use of sunscreens and, on the other hand, to global warming.

We have had a massive coral extinction for years – indeed corals are living organisms, which, by the way, save us from floods and thus from the massive loss of land masses.On the other hand, they are the habitat for numerous fish and other sea creatures.

The Great Barrier Reef in Australia, the world’s largest contiguous coral reef, has shrunk by a whopping 50% in 2015/2016 due to the so-called Coral Bleeching, in which the corals die and change their colour to a very attractive white at first. living corals.The rest is only dead mass, which can no longer fulfil the intended purpose of such a reef.

Dead corals

Healthy corals

Coral bleaching is the name of a bleaching of the stone coral sticks, which can lead to the subsequent death of the corals.

Corals are living organisms.

They belong to the hives and settle in symbiosis with photoythetically active individuals on a limestone layer that grows from year to year. If the zooxanthellae are repelled by the coral, the coral cane loses its splendour of color. This phenomenon can occur locally limited, but also on a large scale and is called coral bleaching. It occurs at too high water temperatures.

Coral bleaching is not new and was observed as early as the 1970s.At that time, however, the event occurred only temporarily and locally, after heavy rains or prolonged low water. But a decade later, it was already being observed worldwide. During elNinno in 1998, coral bleaching was particularly strong in the Indian Ocean and the western Pacific. For months, the temperature of the water was 1 to 3 掳C above average. In the Maldives, 98% of the corals bleach near the surface of the water at this time.

Global warming is causing the global oceans to be warming on an ongoing day-to-day.As a result, corals can no longer recover from other stressors as in the past, and other factors such as water pollution, overfishing, and disease slow their recovery.

As a result, entire reefs can fall victim to coral bleaching and die on a large scale.

In addition, the increased water temperatures not only lead to coral bleaching, but also reduce the ability of the surviving corals to perpetuate.

What will happen when the corals will one day no longer be there is obvious.

On the one hand, the irreparable loss of the habitat available to humans and a serious change in the landscape with ‘port cities’, none of which would have thought possible that they would once even be close to an open water. Would.And the loss of an important food source, as the marine life in the reefs counters providing food for many of the edible fish we use. With the global famine it has triggered, it would be a safe death sentence for billions of people.

Now there are people who say, “Well, 2 degrees Celsius, that’s not that much!”

True, little sounds.

However, a simple example can show what two degrees mean for a living organism, namely if one imagines that one’s own body temperature is on average about 36.7 degrees.

But how does a person feel when he suddenly has a temperature of 38.7 degrees?

Right, he feels feverish, sick and weak.And that is exactly what is happening with the corals, except that they do not get up from the hospital bed after five days of colds, but this is a permanent condition that will get even worse if we do not act.

By the way: If you don’t have children yet, you should have photos of corals ready, if you want to show them some in 20 to 30 years.

This is, for example, the calculated period during which the last reef will also have disappeared and the consequences described above will occur if we do not manage to reduce the fever of the seas again by 2 “ridiculous” degrees.”

Finally, the Netflix documentary on this topic, of which the trailer is attached as a link, is recommended to everyone.
