What are some of the mammoths that would otherwise be unable to meet that could choke in the future due to climate change?

In recent decades, "global warming" has been a recurring topic and a cliché, and as the phenomenon of global warming becomes more apparent, the issue is gaining more and more attention.

Global warming is a phenomenon related to nature and its causes are complex. Simply put, it is a global warming due to the accumulation of the greenhouse effect.

The cause of the greenhouse effect is related to the excessive emission of greenhouse gases such as carbon dioxide. In the past 20 years or so, the temperature of the Tibetan plateau has increased by 3 degrees Celsius.

The hazards and effects of global warming are significant, such as the heat energy from rising temperatures, which provides enormous kinetic energy to the air and oceans, leading to natural disasters such as hurricanes and tsunamis.

Rising temperatures draw moisture from the land, causing widespread drought in the interior and resulting in reduced food production.

The temperature rises, causing the glaciers to melt, and the ancient bacteria beneath the ice, may awaken again.

Numerous foreseeable and unforeseeable disasters will ensue as global temperatures rise, and even more terrifying is the series of chain reactions that will ensue.

For wild animals, some otherwise unmeetable mammals, affected by climate change, may intersect with each other's territories and thus fight.

Forest line moves up, money leopards and snow leopards appear in the same frame

The golden leopard and the snow leopard, two of the more similar big cats, do not normally see each other.

Although money leopards and snow leopards have a large environmental homogeneous distribution in the southwest of China and other regions, for example, in the Sanjiangyuan area and Gongga Mountain, both live in the wild.

However, the money leopard is a species of low altitude forest ecosystem, while the snow leopard is a species of highland snow mountain ecosystem. They have different habitat preferences, so although they both live in one place, the difference between them is like one lives in the bottom bunk and the other lives in the top bunk, and their microhabitats are separated from each other.

But this is not absolute. Once the environment changes, there will be an intersection between the two. Global warming has affected the survival of snow leopards. The original dividing line between money leopard and snow leopard habitat is basically the forest line.

Climate change has brought about changes in rainfall, altering the supply of water in the high mountains, affecting the distribution of vegetation and causing the forest line to move upwards. The money leopard, which originally lived in the lower elevation forest areas, also followed the forest line and kept moving up to higher elevation mountains.

This makes the original "bunk" relationship broken, and the leopard repeatedly wades into the snow leopard's area of activity.

This is not alarmist or unwarranted speculation, in fact there is enough evidence to prove this phenomenon.

In February 2016, money leopards and snow leopards were photographed successively on a 4 km high ridge erected in the Gongga Mountain Reserve in Sichuan.

In July, similar images were captured in the snow leopard habitat in Qinghai, with the money leopard and the snow leopard appearing one after the other in front of the camera.

In January 2020, money leopards and snow leopards were also photographed together in Tibetan territory in succession. All evidence suggests that the ranges of the money leopard and the snow leopard have, to some extent, intersected.

For now, the intersection only occurs on the fringes of the two territories, but it's hard to say if there will be a greater intersection in the future as temperatures rise.

Both the golden leopard and the snow leopard are large predators, and both are similar in their diet, with medium and large hoofed animals such as rock sheep, sheep and wild boar as their main prey, so there is inevitable interspecific competition between the two.

In the future, will the two be at each other's throats because of competition for common, limited prey resources? I believe you and I both have the answer. But when it comes to a real fight, the snow leopard fears that it will hardly be a match for the money leopard.

Brown bears heading north for food meet polar bears heading south to escape disaster

In addition to affecting the distribution of vegetation and causing an upward shift in the forest line, a typical feature of global warming is that it causes glaciers to melt.

Generally, after pregnancy, female polar bears leave the ice briefly to give birth on land along the coast, and then bring their cubs to the ice when they have some mobility.

So normally, the vast majority of male polar bears spend their entire lives on the ice. The vast majority of female polar bears spend the majority of their lives on the ice. However, climate change has caused the ice to melt, and many polar bears have had to move south to escape the disaster.

In contrast to the brown bears, as temperatures rise, the distribution boundaries of terrestrial plants continue to move further north, and the communities of animals that depend on vegetation will gradually move north.

Brown bears are more mobile animals, and adult males in particular are more notable for their exploratory behavior, so they tend to be the first to head north for food.

For example, until 1996, there had never been a single sighting of a brown bear in the northern part of Manitoba, Canada.

In the decades that followed, however, brown bears came into view, with a staggering 12 sightings alone, indicating a local presence.

What are some of the mammoths that would otherwise be unable to meet that could choke in the future due to climate change?

On the one hand, the polar bears that have gone south to escape the disaster, and on the other hand, the brown bears that have gone north to feed, then the two are bound to meet on some coastlines.

In Alaska Beaufort Sea coastline extensions and other areas, there are often whale carcasses, these carcasses for polar bears and brown bears, is the most easily accessible meal, the two will often be fought. These battles are often called "whale carcass battles".

Polar bears are meat eaters, brown bears are omnivorous, but the brown bears up north will increase the proportion of meat eaters because it is more difficult to obtain food of a plant nature, so you can imagine how fierce the competition will be between the two, in order to compete for the whale carcasses.

Affected by climate change, money leopards and snow leopards, which originally did not intersect, became available to meet, while polar bears and brown bears, which originally did not intersect much, fought over food.

The two pairs, in fact, are more obviously visible, and in fact clouded leopards and Bengal tigers, among others, have been observed to appear at higher altitudes, and their arrival is bound to add a new element of uncertainty.
