Climate change is making the Arctic GREENER

Climate change is making the Arctic GREENER as warmer temperatures make trees and plants bloom in the icy world.

  • Scientists are using drones and satellites to track levels of Arctic vegetation
  • The Arctic is normally a vast and arid expanse of frozen land with little foliage.
  • But a recent analysis has found that trees and plants thrive in the Arctic

Ecologists are on ‘red alert’ as warmer temperatures caused by climate change make the Arctic green.

The Arctic is normally a vast and arid expanse of frozen land, but higher temperatures now allow foliage to thrive.

According to a new study, trees and plants are found in areas that were once frozen perennially.

The disturbing phenomenon, called ‘Arctic ecologization’, is being studied by researchers using drones and satellites.

A group of 40 scientists from 36 institutions, led by two National Geographic explorers, are behind the great project.

As summer temperatures in the Arctic heat up, snow melts earlier and plants begin to form leaves earlier in the spring.

Tundra vegetation is spreading to new areas and in areas where plants have always survived, they are now blooming.

The lead author of the study, Dr. Isla Myers-Smith, of the Faculty of Geosciences at the University of Edinburgh, said: “ New technologies, including sensors in drones, airplanes and satellites, are allowing scientists to track patterns ecologization emergencies found within satellite pixels that cover the size of soccer fields. ‘

Changes in vegetation alter the way in which carbon is captured and released into the atmosphere.

Small changes in this balance could significantly affect efforts to keep warming below 1.5 ° C, a key objective of the Paris Agreement.

But researchers in Europe and North America also found that the Arctic greening, which can be seen from space, is caused by several factors.

The warming of the soil is important, the researchers found, but so are the changes in the melting time of the snow and the humidity of the landscapes.

The new study was published in the journal Nature Climate Change.

The team behind this says that it is vital to understand global climate change because tundra plants act as a barrier between the warming of the atmosphere and the huge carbon reserves stored in the frozen soil.

Lead co-author Dr. Jeffrey Kerby, who was a member of Neukom at Dartmouth College while conducting the research, said: ‘In addition to collecting new images, advances in the way we process and analyze this data, including images that have decades of antiquity, they are revolutionizing the way in which we understand the past, the present and the future of the Arctic. “

Alex Moen, vice president of exploration programs at the National Geographic Society, added: “We look forward to the impact this work will have on our collective understanding of the Arctic for generations to come.”

WHAT DO THE EXPERTS PREACH FOR THE DESTINATION OF PLANTS AND PLANET ANIMALS?

Experts say that nature is in more trouble now than at any other time in human history with extinction looming over more than a million species of plants and animals.

That is the key finding of the first comprehensive United Nations (UN) report on biodiversity: the variety of plant and animal life in the world or in a particular habitat.

The report, published on May 6, 2019, says that species are being lost at a rate tens or hundreds of times faster than in the past.

Many of the worst effects can be prevented by changing the way we grow food, produce energy, deal with climate change and eliminate waste, according to the report.

The 39-page summary of the report highlighted five ways people are reducing biodiversity:

– Convert forests, grasslands and other areas into farms, cities and other developments. The loss of habitat leaves plants and animals homeless. About three quarters of Earth’s land, two thirds of its oceans and 85% of crucial wetlands have been severely altered or lost, making it difficult for species to survive, according to the report.

– Overfishing of the world’s oceans. A third of the world’s fish stocks are overexploited.

– Allow climate change by burning fossil fuels to make it too hot, humid or dry for some species to survive. Almost half of the world’s land mammals, not including bats, and almost a quarter of the birds have already suffered their habitats with global warming.

– Polluting the earth and water. Each year, 300 to 400 million tons of heavy metals, solvents and toxic sludge are poured into the waters of the world.

– Allow invasive species to displace native plants and animals. The number of invasive alien species per country has increased by 70 percent since 1970, with a species of bacteria that threatens almost 400 species of amphibians.
