Uncharted Territory: WHO Warns on Climate Change

The Guardian reported on the World Health Organization’s report recent assessment of record temperatures in 2016 and implications for the future. “Even without a strong El Niño in 2017, we are seeing other remarkable changes across the planet that are challenging the limits of our understanding of the climate system. We are now in truly uncharted territory,” said David Carlson, director of the WMO’s world climate research programme.

Here’s a clip:

2016 saw the hottest global average among thermometer measurements stretching back to 1880. But scientific research indicates the world was last this warm about 115,000 years ago and that the planet has not experienced such high levels of carbon dioxide in the atmosphere for 4m years.

2017 has seen temperature records continue to tumble, in the US where February was exceptionally warm, and in Australia, where prolonged and extreme heat struck many states. The consequences have been particularly stark at the poles.

“Arctic ice conditions have been tracking at record low conditions since October, persisting for six consecutive months, something not seen before in the [four-decade] satellite data record,” said Prof Julienne Stroeve, at University College London in the UK. “Over in the southern hemisphere, the sea ice also broke new record lows in the seasonal maximum and minimum extents, leading to the least amount of global sea ice ever recorded.”

What Does The Future Hold?

It may be hard to understand why warming and increased water content in the atmosphere would cause desertification, but it is quite simple if you think about it. When water is heated, it evaporates and lifts up into the atmosphere where it condenses and falls again. However, in a desert or arid region, any moisture that lifts up, does not fall down in the same place. This is a natural process that is the result of wind cells on the planet stemming from equatorial heating. Unfortunately, the earth is heating more rapidly and water is spread further and further from areas that need it, like Chinese deserts or the Sahal in Africa. The input of energy into any system will cause a reaction and the more energy, the higher the magnitude of such a reaction.

This is yet another example of people who do not cause the majority of climate changes being affected the most by climate change. Rural people all over the world are being impacted and not with just hot days, they are losing their way of life and resources to food. This is a positive feedback loop that will accelerate with time and there is probably no going back from something like this. There is development of solar panels that are de-desertifying some places in Africa, but the problem of government intervention is just as bad or worse in China. This is a human rights issue that must be looked at as such; for, we all have the right to life, liberty and happiness… not just Americans.
