It is not, of course, possible to change the climate. Climate has no value associated with it, so there is nothing that can change. A desert climate will always be a desert climate. A mountain climate will always be a mountain climate. 'Climate' is a subjective description, not an objective term.
Anyone claiming that climate can 'change' is simply denying English.
The Church of Global Warming claims the Earth is somehow warming. They blame the Holy Gas CO2. To warm the Earth, some additional energy is needed, and CO2 is not a form of energy.
The 1st law of thermodynamics states E(t+1) = E(t) - U where 'E' is energy, 't' is time, and 'U' is work. CO2 is not work, and is not energy, yet the Church of Global Warming ignores this theory of science and claims energy is increasing anyway.
The Church of Global Warming states that it is possible to measure the temperature of the Earth, but that is not possible. There are simply nowhere near enough thermometers to even begin a sensible statistical analysis of this kind. Anyone that tries to claim they know the temperature of the Earth is bullshitting you. Yes...that includes government agencies.
