147. Attention to Climate is Urgent

19 Feb

The vast majority of nations in the world understand the urgency of climate solutions. We already have worse hurricanes, new flooding, forest fires, glaciers and polar caps melting, sea levels rising, etc. The city of Venice, Italy is already sinking and flooding due to climate factors. Major USA coastal cities and most of Florida will soon be at risk.

Our President refuses to recognize this vital problem because it does not suit his billionaire friends, like the Charles and David Koch of Koch Industries. Making proper changes would cost them a few billion out of their 100 or so billion in assets. Helping his extremely rich friends (and donors) is more important than saving millions of lives and in other ways protecting the USA and many others in the world.

Two very authoritative reports have definitely concluded that the average global temperature is increasing, and the increase is caused by human activities, such as burning fossil fuels. (The Koch family has been in the oil business for decades.) One report is by a United Nations Special Scientific Panel released October 8, 2018. This report indicated that the climate is changing faster than originally anticipated. The other report is the “Fourth National Climate Assessment” (Nov. 23, 2018) by US Global Change Research program. This report is from Trumps gov and he only very reluctantly released it. The official report summary says: “Climate change creates new risks and exacerbates existing vulnerabilities in communities across the United States, presenting growing challenges to human health and safety, quality of life, and the rate of economic growth.”   Trillions of dollars and millions of lives are at stake. Contrary to his claim of “draining the swamp,” his cabinet is full of climate deniers and promoters of CO2 pollution.

The Trump position on climate-change has vacillated like many of his other concerns. In 2009 his family was a major part of a business coalition that asserted “If we fail to act now, it is scientifically irrefutable that there will be catastrophic and irreversible consequences for humanity and our planet.” Later, when running for President he labeled the issue as a “hoax” and then later, not a hoax. He said “he does not believe it.” At one time he said that the climate will change back again. When Amy Klobuchar spoke in a freezing snow storm, he inferred that this disproves global warming. Trump does not understand that local weather is not relevant to global average temperature increases. Trumps Secretary of State Tillerson urged him not to withdraw from the Paris Climate Agreement. That apparently led to his being fired.

Recent scientific research has indicated that we have about 10 years to make major changes in climate factors, such as burning fuels that send carbon dioxide into the atmosphere. We must spend some money on converting to battery operated cars and converting to cleaner power plants. Our gov must support research and incentives in these areas.  We must also support promising research on methods for removing carbon dioxide from the atmosphere. Time is running out and all possible solutions must be supported.  Please see my previous blogs for more discussions on climate.

 

 

 

 

 

 

 

132. Latest Climate Change Info: Simplified

29 Dec

It is vital that our government supports climate change programs.The dangers are serious and some harmful effects are already happening. Helping people and leaders to understand the science is my contribution. Here are the fundamentals, briefly:

Light from Sun >> Heats earth >> Heat energy Rises /\ /\  from earth
Some rising heat is blocked ]]]] from escaping by gases like CO2
Burning fuel increases CO2 causing more ]]]]]] blockage & warmth

More Detail:
Light from the Sun passes through our atmosphere and warms our planet. The resulting heat rises and some is blocked from escaping into space by “greenhouse” gases: carbon dioxide (CO2), methane, water, and others. Small quantities of these gases are naturally in the atmosphere, and the amount is relatively stable.

But when we burn fuel and create more heat-blocking CO2, there is excessive planet warming. CO2 and other “greenhouse gases” are like a blanket around our planet. See below for more scientific detail.

How do we know that planet warming is caused by human activity?
1, The carbon dioxide emitted by burning coal, natural gas, and oil has a unique chemical pattern — and the additional CO2 in the atmosphere bears that signature. (See below for more detail.)

2. The CO2 and warming are closely correlated with the history of the industrial revolution, which involved the burning of coal and gasolene. As the usage of fossil fuels increased, the warming increased. During the history of the Earth, there were temperature cycles, but these natural cycles are very much slower than the current rapid temperature warming. No other “natural” factors could have caused this increase. See this NASA reference for actual data:  https://climate.nasa.gov/evidence/

What are the dangers of global warming? Warming causes arctic and other northern ice to melt. This is already well established by photographic evidence. The consequence is warmer oceans, rising sea levels, and changes in ocean currents.

The warming of oceans increases the strength of hurricanes. In recent years, hurricanes are worse than before. Changes in ocean currents shift land temperatures and rainfall so that some lands (like California) are drier and other places are flooded. Inhabited land that is close (or even less than) sea level is starting to flood, due to a slight rise in sea level. A good example is flooding in Venice, Italy, where the sea level has consistently risen by a total of 26cm since 1870. Many highly populated coastal areas of the USA are vulnerable. Some ocean islands are no longer habitable.

Scientists have spent thousands of hours recording and studying these factors. All of these facts are published in reputable scientific journals and magazines, such as Scientific American and Science. All reputable scientists support these findings. A recent official government report and NASA report supports all these facts. Politicians sometimes dispute these facts because their donors might need to spend money to correct their operations. Scientists are not political with respect to science.

Added scientific clarifications
Rising heat energy (infrared radiation) is effectively  “blocked” by CO2 and other greenhouse gases. Most of our atmosphere consists of oxygen and nitrogen, which are small molecules and have little effect on rising heat. Greenhouse gases like CO2 have larger molecules and can absorb heat energy. Shortly after absorption, the heat energy is re-emitted in any direction. The part that goes downward tends to warm the earth. Long before humans inhabited the Earth, greenhouse gases were in the atmosphere at an almost fixed level as a result of opposing processes that produced an equilibrium. These gases warmed the Earth enough to make it habitable for humans and other animals. Burning fuels has increased the heat, causing harmful effects.

CO2 from fuel burning can be identified because it contains tiny amounts of certain inert (noble) gases, Other “natural” CO2 has a different pattern of these inert gases. This is often referred to as a “fingerprint.

Scientists have been working diligently on the problem of added global warming. There are basically two types of solution:  1. Reduce the burning of fuels by producing alternative energy like windmills and solar arrays, and 2. Develop industrial processes for removing greenhouse gases from the atmosphere. Number 1 is already in major use. Number 2 is being developed by researchers, but the effectiveness is not yet known . Our gov needs to support BOTH of these efforts, trying to remove CO2 (etc) from the atmosphere will not be enough.
