Global warming will destroy tropical oceans very soon

Global warming will destroy tropical oceans very soon

Scientists have created a model of the effect of temperature changes on the state of wildlife. She helped to realize what terrible future humanity has. The creation of this model is shocking: soon, the ecological systems of the planet will undergo irreversible changes. Scientists believe that the consequences of changes in tropical oceans will be irreversible.

The reason for the changes lies in global warming taking place on our planet. Global warming will gradually lead the planet to a catastrophic loss of biodiversity. If greenhouse gas emissions do not decrease now and today, then by 2030 the planet will face the inevitable death of many ecological systems.

This situation will cause the mass extinction of many species of animals and birds. Our planet had never warmed up so fast before and had never warmed up so simultaneously before. At the rate of anthropogenic carbon emissions that are observed now, by 2100 the Earth will warm up by 4 additional degrees. Scientists from the UK, USA, South Africa have compared observations over the past 150 years.

To these data, they added the results of observations of climate change and the distribution of 30 thousand species of fish, reptiles, mammals. Then they divided the globe into conditional segments of 100 square kilometres and created models of temperature trends and their impact on wildlife in each particular segment.

Such a model showed that with ordinary emissions of carbon dioxide into the atmosphere, about 73 per cent of the species of the animal world will be in a catastrophic situation due to global warming. Alex Pigot of the Center for Biodiversity and the Environment at London University College believes that animals have to go through the "temperature horizon." But not many will be able to do this because they will not be able to adapt to new elevated temperatures.

As soon as the planet overcomes this temperature threshold, mass extinction of animals, birds, and fish will begin on Earth. If the level of warming does not exceed 4 degrees, then 15 per cent of living organisms will be forced to survive extreme heat. It will cause irreversible damage to ecosystems. With a temperature increase of 2 degrees, this percentage will be 2.

Until 2030, the expected changes will occur in the tropical oceans. Concurrent phenomena, such as massive discolouration of the Great Barrier Reef, indicate this. By 2050, irreversible changes in the ecosystems of the oceans will occur everywhere.
