NASA video shows global warming in 30 seconds

The atmosphere and the ocean are warming up, the glacier melting is intensifying, the sea level keeps rising, and the carbon dioxide concentrations are reaching unprecedented levels. Climate change is a reality and NASA scientists already raised the alarm: 2014 has been the warmest year on record since 1880. This is represented in this graphic by the Japan Meteorological Agency (JMA), entity in charge of carrying out studies on global temperature:

If any doubt remains, a video launched by scientists at the NASA Goddard Institute for Space Studies (GISS) in New York, shows a time series of the global average temperature increase between 1880 and 2014:


Scientists point out that, despite fluctuations in climate patterns that have always been present in average temperature from one year to the next, there is a constant increase of the greenhouse gas levels in the atmosphere.  As a result, an increase in global temperatures in the long term is expected, which has risen 0.8 degrees since 1880 and keeps on rising.

The most recent report from the Intergovernmental Panel on Climate Change (IPCC), issued last November, indicated that climate change is a reality, mainly caused by mankind since the mid-twentieth century.

The IPCC states that we must cut greenhouse gas (GHG) emissions between 40% and 70% by year 2050. Moreover, by the end of the century, there should be no emissions. This is the only way to reach the key objective to limit temperature increase to 2 ºC, according to the experts.

Figures of climate change

  • CO2 concentration in the atmosphere increased 31% between 1750 and 2000, that is, during production industrialization.
  • The average temperature on Earth increased 0.84 °C only between the industrial era and 2010.
  • 3.7 °C is the temperature increase trend if we continue the same emission patterns.
