What if global warming is a hoax and we create a better world for nothing?
What if global warming is not a hoax and we do nothing?
Carbon dioxide, water vapor and other large atmospheric molecules have a blanketing effect on heat being radiated away from the surface of the Earth as infrared radiation. Called the Greenhouse Effect, it is a Physical Law and has helped regulate global temperature for billions of years. Indeed, at one point early in Earth’s geologic history, carbon dioxide became so depleted that our planet became a giant ball of ice (Snowball Earth).
The next time that carbon dioxide was out-of-balance was when very prolonged volcanic basalt flows (Siberian Traps) caused so much to be pumped into the atmosphere that the oceans acidified and global temperatures soared (The Great Dying). Though lesser extinctions caused by an over abundance of CO2 have occurred, CO2 is normally benign.
When the carbon cycle is balanced, the amount of CO2 in the atmosphere decreases and increases with the seasons and with the Milankovitch Cycle (planetary orientation to the sun). At these times, CO2 levels lag behind temperature levels. However, when volcanic “flood basalts” (LIPs) occur, increased CO2 levels amp up the Greenhouse Effect — global temperatures then begin lagging behind carbon dioxide levels.
At this time in Earth’s history, the carbon cycle is being unduly influenced by the burning of carbon that has been stored underground for eons of time. The effect is the same as the basalt flows had when they released vast amounts of carbon dioxide.
