6 most obvious consequences of climate change

Climate change sea makes flowers bloom earlier, the breeding season of animals changes and military activities increase sharply in the Arctic.

The global average temperature has increased by about 0.74 degrees Celsius over the last 100 years. Analyzing the role of climate change in each weather event is difficult, but in fact the scientific community has clearly seen some consequences, Livescience said.

Flowers bloom earlier, many plants disappear

A study of plants around Concord, Massachusetts, USA shows that, compared to the last decades of the 19th century, the flowering time of 43 of the most popular tree species in the region came earlier than average. 10 days. Many other plants, including 15 orchids, have disappeared.

The blooming time of many flowers has changed due to the warmer earth.

Military activity increased markedly in the Arctic

When the Arctic ice melts, the whole world cares about the resources below the ice. The US Geological Survey estimates that the Arctic owns 30% of gas and 13% of undiscovered oil reserves in the world. Therefore, military activity in the Arctic tends to increase. The US, Russia, Denmark, Finland, Norway, Ireland, Sweden and Canada - countries with a portion of the territory located in the Arctic Ocean - held many talks on security in the Arctic and problems border. Many countries, including the United States, are sending soldiers to the north pole of the earth to prepare for border patrol and disaster prevention activities when the presence of people in the Arctic is growing.

Breeding season of animals changes

Due to rising temperatures, the penguin breeding season is changing. A study, just published in March, proves that Gentoo penguins have adapted very quickly to warmer weather, because their reproductive activity does not depend on sea ice as winged birds. other penguin.

Penguins are not the first animals to adapt to climate change. Many animal protection centers in the US say they have increased the number of cats abandoned by the cat's breeding season lasts longer.

The life of a white bear is more difficult

A study in 2011 showed that white bears must swim longer to find stable ice sheets. Rapid melting speed in the Arctic forces many white bears to swim continuously for more than 12 days to find food. The death rate of baby bears increases by 45% if they have to swim more than 48km, while that ratio is only 18% if they swim over shorter distances.

The feeding of white bears in the Arctic becomes more difficult because of the melting of the ice.

Animals move higher

Many animals move to higher positions to adapt to the rise in temperature. For example, the amount of snow on the mountain peaks in winter allows the elk in northern Arizona, the United States to find food on the higher slopes during the winter. Elk eat a variety of plants important to birds, such as ferns and yang leaves, causing the number of birds to decrease.

The movement speed of animals increases

Animals are moving away from their habitats at an unprecedentedly large rate: an average of 17.6 kilometers towards the earth's poles each year. Movement speed reached the highest level in areas where temperature increased the most. For example, the Cetti warbler has traveled more than 150km north in the past two decades.
