Is current climate change man made or a natural occurrence? Studies show that the greenhouse gas CO2 is increasing at a rate never before seen in nature. Similarly, ocean temperature is increasing faster than ever recorded. The climate deniers thought they'd scored some points, claiming that the increase in air temperature was slowing. Science has two responses to this. First, NASA says the hottest years on record, going back to the 1880s, are 2014, 2010, 1998, 2013, 2007, 2009, 2002, 2003, 2006 and 2011. Second, it was not realized until recently that, to quote an IPCC report "Most of the additional energy stored in the climatic system since 1970 has gone into ocean warming. The remainder has melted ice and gone into the atmosphere."
