Eliminating Coal-Fueled Power Plants: The Impact on Global Warming
Coal is the most carbon-intensive of the three major fossil fuels: natural gas, petroleum, and coal. Due to its high carbon content, it is also considered by many to be the dirtiest of these fuels. The global elimination of coal-fueled power plants would have a profound and positive impact on the ongoing effort to combat climate change. Although the complete cessation of coal usage would be an enormous step, it would likely not be sufficient on its own to fully address global warming concerns.
Reducing Greenhouse Gas Emissions
While the cessation of coal use would significantly reduce greenhouse gas emissions, other sources of carbon dioxide and methane would still contribute to the problem. Methane, a potent greenhouse gas, is released via natural sources such as cattle, gas leaks, and landfills. Stopping the usage of coal would likely reduce the global discharge of total greenhouse gases by about 25-33%. This is a substantial reduction, but not a complete solution. It serves, however, as a crucial first step in the battle against climate change.
Immediate Environmental Benefits
The cessation of coal combustion would bring immediate environmental benefits, reducing air pollution that includes particulates, sulfur oxides, and mercury, which can make its way into the ocean and food chains. The rapid elimination of coal usage, especially in the United States, should have been prioritized decades ago to mitigate these immediate impacts.
Long-term Climate Considerations
The atmospheric concentration of CO2 is currently at about 420 parts per million (ppm) dry air, compared to pre-industrial levels of around 280 ppm. To truly halt climate change, the world would need to reduce atmospheric CO2 levels to between 300 and 350 ppm. This is a significant challenge that will require the implementation of drawdown techniques. While eliminating coal would significantly aid in this effort, it would not be sufficient on its own.
Challenges and Future Steps
The elimination of coal would lead to a reduction in energy generation, with consequently less heat released into the environment and less carbon dioxide emitted into the atmosphere. This could result in a reduction in the rate of global warming by approximately 35-45%. However, to support current levels of energy demand from renewable sources, the manufacturing and installation of this equipment would need to occur either concurrently with or before the decommissioning of coal-powered plants.
Reduced CO2 emissions could lead to greater plant growth, especially as the rate of warming may slow down and the pressure of aridity eases. This is particularly important if forests are no longer being harvested for profit, as forests play a critical role in creating microclimates and overall ecosystem health.
The reduced discharge of oceanic heat currents could also slow down the warming of ocean water temperatures and potentially delay the melting of ice shelves and the release of surface glacial ice. Maintaining water temperatures near -2°C, especially during polar winters, would be crucial to preserving these delicate environments.
The cessation of coal usage would indeed bring air quality improvements, but the full impact on climate change would take years to materialize. Climate change is a long-term phenomenon, and even significant reductions in emissions may not yield immediate observable results.
While these steps towards reducing coal use are essential, they will not satisfy the more extreme views of some climate change activists who advocate for global, one-world Marxist governance. Achieving meaningful climate action will require a multifaceted approach, including technological innovation, policy changes, and international cooperation.
