For example, Mike contributes $30 per month (after tax) to a disability plan. His employer also contributes $30 per month to the same plan. Mike becomes disabled. Under the terms of the disability insurance contract, Mike receives $3,000 per month for each month he is disabled.
What is climate change? Climate is usually defined as the average weather in a place. It includes patterns of temperature, precipitation (rain or snow), humidity, wind and seasons. Climate patterns play a fundamental role in shaping natural ecosystems, and the human economies and cultures that depend on them.
But climate change is not an on-off switch. It is a continuing process. The sooner we stabilise atmospheric concentrations of greenhouse gases, the sooner we can reduce our impact on the climate and minimise the risk of reaching tipping points that will make preventing further warming even harder.
