Proactive disclosure Print version | Temperature rising: Climate change in southwestern British Columbia Climate has always changed Scientists now know that Earth's climate has been much more stable and far warmer during the last 10 000 years than at any other time in the last 100 000 years. This remarkable stability has allowed human society to flourish. Even so, there have been changes in climate over this period, with far-reaching effects. A vast sheet of ice more than 1.5 km thick covered what is now Vancouver at the peak of the last ice age 16,000 years ago. Climate warmed rapidly at the end of the ice age, melting ice sheets and creating more habitable conditions.
