  • The effects of global warming are the ecological and social changes caused by the rise in global temperatures. There is a scientific consensus that climate change is occurring, and that human activities are the primary driver.[1] Evidence of climate change includes the instrumental temperature record, rising sea levels, and decreased snow cover in the Northern Hemisphere.[2] According to the Intergovernmental Panel on Climate Change (IPCC), most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in human greenhouse gas concentrations.[3] Projections of future climate change suggest further global warming, sea level rise, and an increase in the frequency and severity of some extreme weather events.[4] Parties to the United Nations Framework Convention on Climate Change (UNFCCC) have agreed to "stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system."[5]

  • 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).

Bosque El Imposible, El Salvador | Rainforest Alliance - 0 views

  • Because of it size and biological diversity, Bosque El Imposible National Park is considered the most important natural area of El Salvador.
  • Located in the department of Ahuachapan, El Imposible contains a highly threatened dry tropical forest that forms part of the coastal mountain range Apaneca-Ilmatepec. The 9,000 acre forest ranges from 900 feet to 4,300 feet above sea level and is home to the country's most crystalline water. Bosque El Imposible's unique topography lends a splendid beauty to this refuge. More than 500 species of birds live there, including the great curassow, king vulture and turquoised-browed motmot. Ocelots are also found in Bosque El Imposible. Traders
  • Bosque El Imposible National Park is one of the last remaining remnants of El Salvador's original forests. More land needs to be purchased or maintained by private landowners as forest. If a forest is too small, there is little hope to protect its plants and animals. This forest is El Salvador's hope for the future. If SalvaNATURA can add habitat to the park and work with landowners to restore eroded land outside El Imposible's borders, then the country's wildlife will face a more certain future.

  • 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.
