  • We can't be sure because average global temperatures are hard to compile accurately, and all of the "official" institutions keep revising their historical data.

  • Yes. Temperatures over the past 2000 years, reconstructed using proxies such as ice cores, tree rings, etc., show a slow long term cooling trend changing into relatively rapid warming in the 20th century. This is known as the "hockey stick" graph.

  • Yes. The polar icecaps are melting at an accelerating rate.

  • Yes. Glaciers are melting at an accelerating rate.

  • Yes. Sea levels are rising at an accelerating rate, due to all the melted icecaps and glaciers.
