  • Measurements from Listvyanka reveal some interesting trends related to the timing of ice break-up; most notably that it is occurring earlier now than in the past. In the 1870s, thawing began around May 10; today, it often begins in late April. One study by a Swiss researcher calculated that the thawing date had moved by half a day per decade between 1869 and 1999. However, the most rapid change (about 3 days earlier per decade) occurred between 1869 and 1920. Since 1920, the date of ice breakup has remained fairly constant at Listvynaka. Ice formation, however, has occurred later in the winter, so the overall ice cover doesn’t last as long as it once did.

  • Climate change refers to man-made changes in our climate. It is often also called ‘global warming’, as one of the most well-known effects of climate change is a steady rise in the Earth’s temperature
  • Other effects include sea levels getting higher, ice melting at the poles, and extreme weather events like hurricanes and droughts becoming more common (2). Many animals are also struggling to survive as their habitats change (3).
  • Climate change is caused by an increase in the amount of gases in our atmosphere that trap heat. These gases occur naturally and ensure the Earth is maintained at a life-supporting temperature, in a process called ‘the greenhouse effect’. However, human activities that burn fossil fuels like coal and oil are increasing the amount of these gases in our atmosphere, causing the Earth to warm to abnormal levels (2) (4).

  • Scientists are predicting that climate change will cause a mass extinction of many species of plants and animals. As ice melts in the Polar Regions, polar bears and emperor penguins are losing vital habitats, the ocean is also becoming more acidic which is killing many corals. Species that live or breed on low-lying remote islands, like marine turtles, are threatened by rising sea levels and extreme weather, and many plants, which cannot move to find new habitats, are disappearing from parts of their range, due to drought and higher temperatures (3). It is too late to reverse many of the effects of climate change. But to limit the damage done by climate change many countries have pledged to limit the amount of greenhouse gases in the atmosphere. Renewable energies, such as wind, tidal and solar energy, are being developed so that we do not need to keep burning fossil fuels (1) (5).

  • Now researchers in Norway have discovered that not only is the warming trend continuing and melting glaciers, it is doing so much faster than they had previously predicted. In fact the melting trend is becoming so quick that many researchers are having trouble keeping up with the data which is a real pain in the butt but kind of exciting at the same time, kind of the best of both worlds.
