Global Warming

In For a Future I start off by explaining global warming. Climate Change or global warming is but one of the nine environmental thresholds on which the diversity of life in the Earth’s biosphere depends. According to the Stockholm Resilience Centre, of the nine planetary boundaries, four of the thresholds have been breached. In the case of global warming, CO₂ in the atmosphere keeps the sun’s energy from leaving the planet. A warming planet causes the climate to change. Humans have emitted CO₂ into the atmosphere for as long as they have used fire to meet their survival requirements. The Industrial Revolution greatly increased the direct and indirect energy individual humans consume to survive. Individual energy usage increased further in post-World War II societies that the consumers in today’s developed world take for granted. Most of the greenhouse gasses have been released since the last World War.
