Hello everyone it's me the shy one. This is like my second post so here are the 4 questions.
1) What challenges do Arctic areas face as a result of global warming?
2) What measures could help deal with the problem?
3) What do you predict will happen to Arctic ecosystems if no measures are taken to reverse the problem of global warming? Explain your reasoning.
4) Which measures do you think are most important to pursue? Support your opinion with reasons.
Like always stay safe from the CARONA!

1.The effects of global warming in the Arctic, or climate change in the Arctic include rising air and water temperatures, loss of sea ice, and melting of the Greenland ice sheet with a related cold temperature anomaly, observed since the 1970s. 2. An engineer has devised a way to stop Arctic ice from melting by scattering millions of tiny glass beads to reflect sunlight away. Scientists have discovered that melting in Greenland and Antarctica is occurring much faster than they previously thought. 3. The cap of sea ice covering the Arctic Ocean started to shrink when it should have been growing. Temperatures at the North Pole soared more than 20 °C above normal at times. And polar bears prowling the shorelines of Hudson Bay had a record number of run-ins with people while waiting for the water to freeze over. In the span of a few months, all manner of strange things happened. 4. Human basic needs, such as food, water, health, and shelter, are affected by climate. Changes in climate may threaten these needs with increased temperatures, sea level rise, changes in precipitation, and more frequent or intense extreme events. Climate change will affect individuals and groups differently.

Explanation:

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
