American Meteorological Society Finally Takes a Stance On Climate Change

When it comes to climate change, certain groups in the United States are still resistant to the idea despite evidence from the US Military, US Forestry Commission, NASA and assorted independent studies. Now after years of sitting on the fence over the issue, the American Meteorological Society has released its official position on climate change, and they say that the Earth is indeed warming due to human activity.

In an official statement, The American Meteorological Society said: “There is unequivocal evidence that Earth’s lower atmosphere, ocean, and land surface are warming; sea “level is rising; and snow cover, mountain glaciers, and Arctic sea ice are shrinking.”

“The dominant cause of the warming since the 1950s is human activities. This scientific finding is based on a large and persuasive body of research. The observed warming will be irreversible for many years into the future, and even larger temperature increases will occur as greenhouse gases continue to accumulate in the atmosphere.”

The group added that while natural cycles of warming are to be expected, the evidence clearly points to human activity as the cause of the climate change the earth is currently experiencing.

Among the evidence cited includes the fact that all of the 10 warmest years in global temperature records up to 2011 have occurred since 1997, with 2005 and 2010 being the warmest two years in more than a century of global records. Meanwhile in the US, there have been twice as many record daily high temperatures as record daily low temperatures in the first decade of the 21st century.

“It is clear from extensive scientific evidence that the dominant cause of the rapid change in climate of the past half century is human-induced increases in the amount of atmospheric greenhouse gases, including carbon dioxide (CO2), chlorofluorocarbons, methane, and nitrous oxide,” the group said. “The most important of these over the long term is CO2, whose concentration in the atmosphere is rising principally as a result of fossil-fuel combustion and deforestation.”

The society also warned that their simulations have predicted an increased proportion of global hurricanes falling into the strongest categories (4 and 5 on the Saffir-Simpson scale). Also while the total number of storms may not change and heat waves and cold snaps will continue, there will be proportionally more extreme warm periods. Droughts and high temperatures will also put pressure on the world’s crop systems.
