Thawing Permafrost Could Fuel Climate Warming
1. The Arctic is warming more than twice as fast as the rest of the world, and some scientists believe that thawing permafrost — ground frozen since the last Ice Age — is about to release enormous amounts of climate-warming emissions. In the coldest regions of planet Earth, ice binds together soil, rock, sand and organic matter. This layer of permafrost can begin just centimeters below the Earth’s surface. Anywhere cold enough to keep the ground frozen year-round for at least two years counts as permafrost. About a quarter of the Northern Hemisphere contains permafrost.

2. Warmer temperatures in the Arctic are causing snow and ice to disappear. As ice covering the sea shrinks back, it exposes darker waters that absorb solar radiation rather than reflecting it back out of the atmosphere. This is called the albedo effect, and helps explain why the Arctic region is warming so much faster than the rest of the world. This chart shows how much average surface air temperatures have changed at different latitudes since 1960.
3. The Siberian Arctic town of Verkhoyansk in June registered a record high temperature of 38 degrees Celsius (100.4 Fahrenheit) during a prolonged heat wave. Record fires have also engulfed vast swathes of Siberian Russia, emitting more carbon dioxide than Switzerland or Norway do in a year.
4. The boreal forests of the Arctic have evolved to survive and thrive from occasional fires that would naturally occur every few decades or centuries in the region. But the more recent fires are different, scientists say. They are starting months earlier than they ever have before, and are smoldering through the winter as underground ‘zombie fires.’
5. The more intense fires are also burning up peat bogs. A forest might grow back in a few decades and reabsorb the carbon it released when it burned; a peat bog is the accumulation of thousands of years of partial decomposition.
6. The best way to prevent permafrost from thawing is to limit climate change by reducing fossil fuel emissions and protecting forests, scientists say. But once permafrost thaws, there’s nothing that can be done to stop the carbon from being released.
Choose the correct option to answer the questions based on the above passage and graphics.

Read the passage and answer the questions that follow:Australia’s 2019-2020 Bushfire Season was not Normal1. Data from satellite sources assembled by the United Nations Environment Programme’s (UNEP) World Environment Situation Room confirms that the wildfires in Australia in thelast two months of 2019 and the first six weeks of 2020 were far from normal. 2019 was the second hottest year on record since 1880, and Australia recorded its warmest temperatures ever in December 2019.2. “Rising temperatures continue to melt records. The past decade was the hottest on record. Scientists tell us that ocean temperatures are now rising at the equivalent of five Hiroshima bombs a second. One million species are in near-term danger of extinction. Our planet is burning,” says United Nations Secretary-General António Guterres.3. “The trend is very clear: 37 of the last 40 years were the warmest recorded since 1880, and the six warmest years recorded were the last six years,” says Pascal Peduzzi, Director of UNEP’s Global Resource Information Database in Geneva. “For those who think Australia is always burning, graphs clearly show that these fires were exceptional.”4. “This service, accessible via the UNEP’s World Environment Situation Room, is provided for all countries at national and provincial levels. It identifies trends in wildfire activity since 2003, when the data first became available and monitoring began. We have sliced and diced the satellite-based data on wildfires worldwide from 2009 to the present day. We analyse the wildfires’ data by month, type of land cover, protected area, province and nation to produce information products,” Peduzzi adds.Choose the correct option to answer the questions based on the above passage and graphics.Q.What do the reports confirm about the 2019-20 Australian fires?
