Scientists find arctic ice is melting faster than they ever could have imagined / Scrap... - 0 views

  • 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.

Consequences of Global Warming - Global Warming Effects | NRDC - 0 views

  • This has been the warmest decade since 1880. In 2010, global surface temperatures tied 2005 as the warmest on record, according to the National Oceanic and Atmospheric Administration. Scientists say that the earth could warm by an additional 7.2 degrees Fahrenheit during the 21st century if we fail to reduce emissions from burning fossil fuels, such as coal and oil. This rise in average temperature will have far-reaching effects on the earth's climate patterns and on all living things. Many of these changes have already begun.

11 Facts About Global Warming | Do Something - 1 views

  • Since 1990, yearly emissions of carbon dioxide have gone up by about 6 billion metric tons worldwide, which is more than a 20% increase. Almost all of that increase is due to human activities.
  • Carbon dioxide takes 100 years to disperse in the atmosphere. Even if emissions are stopped today, we will still feel the effects for years to come.
  • During the 20th century alone, the average surface temperature of the world has increased by 1.2 to 1.4°F.

  • 2000-2009 was the hottest decade on record, with eight of the hottest 10 years having occurred since 2000.
  • The World Health Organization blames 150,000 deaths per year on the effects of global warming including extreme weather, drought, heat waves, decreased food production and the increased spread of diseases like malaria.
  • The Arctic Climate Impact Assessment has concluded that in the past 50 years, the average temperatures of Alaska, eastern Russia and western Canada have increased as much as 7°F. This rise is almost twice the global average.
  • Sea levels have risen between 4-8 inches worldwide during the last century, and experts predict they could rise as much 2 feet in the next 100 years.
  • Extreme weather doesn't just mean high temperatures. Global warming is causing more intense rainfall and droughts at the same time across the world.
  • At least 279 species of plants and animals are already responding to global warming, migrating north to escape rising temperatures.
  • Coral reefs are highly sensitive to small changes in water temperature. Scientists say if current CO2 emission trends continue, the world's coral reefs could be virtually destroyed by 2050.

  • 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).
