Very Hard to Grasp Global Warming

by Ginosar  

It is so hard to grasp the essence of global warming. It is natural to reject the idea that our beautiful world is changing rapidly and for the worse. The very thought that the stable climate that gives us brisk mornings, beautiful sunsets, green, majestic trees, stable weather and food, is leaving us high and dry, is unacceptable. Even people, who agree that the globe is warming, and that it is human driven, do not fully, internalize this danger. It is simply too much for us. We can not accept it; we are just human after all.

We have been enjoying this climate stability for some twelve thousands years now, from the end of the last ice age. First it allowed us to establish stable agriculture on rich arable lands fed by rivers and steady precipitation. It allowed us to advance from being nomads to stable communal livings, to have leisure, to develop richer culture, science and art. Our stable agriculture allowed civilization to emerge and progress. Any variation in climate from the normal caused vast famines and mass migration of survivors.

 

Stable climate allowed humanity to enjoy more and more physical and emotional leisure and even luxury. The very foundation of our human progress is dependent on this relatively stable climate. For example, stable glaciers melted slowly to give steady river flows for irrigation and pleasure.

 

We built cities where the weather was stable and benign, with little prospects for floods or destructive winds. Winds are driven by temperature differences; global warming increases temperatures, and causes variations of weather. Will the benign weather be impacted? Yes. How much? - We do not know. Typical city winds of 10 to 50 mph may gust later to 80 or higher, toppling trees and lifting roofs. What do we do than?

 

The glaciers, the north and south poles, and the deserts, stabilize the climate by reflecting most sun rays back to space. Otherwise we would have been cooked millions of years ago. We have already changed this delicate balance, and we are starting to see serious impacts. Ice surfaces are melting all over the globe, most glaciers are fast disappearing, and the decreasing Himalayas glaciers supply water to hundreds of millions. Polar and Greenland ice melting fast.

 

Green trees participate in the orchestra of creating life-sustaining oxygen and absorbing excessive CO2. More than 20 percent of the world's oxygen is produced in the Amazon Rainforest that we are burning down every day.

 

The vast oceans, covering two thirds of the surface of our tiny globe, are a source of essential food for a significant portion of the global population. The abundant supply of fish starts with tiny organism fed by the upwelling of nutrients along vast shores, induced by temperature differences at diverse sea depths. As temperatures change, so does the food chain. Less food for a billion people. California and other states already disallowed fishing in several coastal zones.

 

Our oceans both absorb and emit vast amounts of CO2 in a very delicate balance which depends on ocean temperatures. Right now the oceans are emitting more and absorbing less CO2 than a few decades ago, and the increased CO2 makes the oceans more acidic. The lovely coral and fish are not too happy about it. Again, can we live without ample supplies of fish? Over a billion people depend on fish for their main source of food.

 

And we now argue in Congress how much will it cost to save our world from unrepairable damage?

 

Take action: write your 2 US Senators and one House member short, simple, letters to get serious on this crucial issue, telling your own feelings.

No form letters please, they ignore them.

Join an environmental organization too to help you understand the issue and lead you to more action.
