The U.S.Environmental Protection Agency needs to adopt regulations for human emissions of dihydrogen monoxide (DHMO). Last year the Supreme Court ruled last year that carbon dioxide (CO2) qualifies as a pollutant subject to government regulation under existing pollution control laws. The gaseous form of DHMO can produce more adverse effects than CO2. Some people refer to DHMO as dihydrogen oxide.
Humans add DHMO to the air through various activities including combustion of hydrogen containing fuels such as natural gas and petroleum based fuels.
The only alleged adverse affect of CO2 is that it supposedly causes increased atmospheric temperatures through a process that some physicists say doesn't exist. Some climatologists claim that CO2 causes adverse warming by trapping infrared radiation even though physicist R.W. Wood demonstrated in 1909 that trapping IR doesn't cause greenhouses to be warmer.
DHMO is said to be more effective at trapping IR under the process that greenhouse gas believers claim is causing global warming which means it should qualify as a pollutant under the same criteria as CO2. DNMO comprises 2-4% of the atmosphere, but CO2 is less than 0.04% DHMO can cause climate changes even if the greenhouse gas warming process doesn't exist.
One gram of the gaseous form of DHMO can melt almost 7 grams of ice which means adding DHMO to the air can increase the melting of glaciers and the polar ice caps. The same thermal characteristics that allow DHMO to melt ice allow it to prevent temperatures from dropping below a threshold. Scientists have long known that increasing the amount of DHMO in the atmosphere can keep the low temperature above freezing which can increase the melting of ice and prevent it from refreezing.
The severity of flooding and hurricanes depends upon the amount of DHMO in the atmosphere. Severity of both increases with increases in the amount of atmospheric DHMO. Obviously, human DHMO emissions can increase the severity of floods and hurricanes and the EPA should regulate such emissions.
DHMO can corrode metal and damage wood products among other adverse environmental effects. DHMO can adversely affect human health.
Some people might argue that DHMO cannot be a pollutant because it occurs naturally in the atmosphere. The Supreme Court didn't find that claim important regarding CO2. Various natural processes put CO2 into the atmosphere including venting from the oceans and volcanoes. According to the Court's ruling in Massachusetts et. al. v. Environmental Protection Agency the law is so broad that it allows regulation of any chemical released into the atmosphere. DHMO qualifies as a chemical for the same reasons CO2 does.
Plants need DHMO, but they also need CO2. Some greenhouses deliberately increase the amount of CO2 in the air to increase plant growth. The Supreme Court didn't consider the need plants have for CO2 to justify exempting it from government efforts to force the atmosphere to adhere to human law precisely regulating its content.
