What's to debate about when everywhere in the world, there are signs that the earth has warmed. Whether it's climate change or not, the whole planet is experiencing a warming that has melted glaciers, shrunk polar ice, and flooded low masses of lands in oceans. Now, the United Nations has announced that the years between 2000 and 2009 are the warmest since record-keeping began in 1850. Climate scientists are predicting at warmer years ahead. Should this be a cause for concern? It's likely.
Between 2007 and 2009, the Arctic ice cap was reduced to the smallest ever recorded due to summer melt. This opened up new sea routes in areas that used to be ice clad. The situation posed questions on how Arctic life would fare with very little ice since a lot of animals there depend much on solid ice in order to thrive.
According to the National Aeronautics and Space Administration (NASA), the warmest years since 1850 are 2005, 1998, 2007 and 2006, although the difference in temperatures between them are so little to be statistically insignificant. The recent climate change talks in Copenhagen (2009) sought to encourage governments worldwide to help in mitigating greenhouse gas emissions and get their commitment to the cause by implementing solid measures to deal with the problem.
