Short term weather is unpredictable due to chaotic small scale fluctuation. On the other hand climate change is mainly controlled by overall energy balance between the incoming Solar radiation and the outgoing radiation which is more stable and predictable. When so much CO2 molecules are pumped from fossil fuels, basically ancient metamorphed dead organisms, into the atmosphere for so short period, there is a limit that Earth can sustain the climate within in a human-habitable range for all people. We should seek alternative technologies to avoid the future mess and havoc for kids yet to come, and not doing so will cause unbearable pains and suffering in near future. This might be an optimistic scenario: the current generations may have to live up to the mess we made pretty soon.
Environmental terrorism might not be a far fetched option for these people who believes that their life is destroyed by others: when their habitat is destroyed, then what do they have to lose? This option will not make any sense for them in the end since doing so will end in writing themselves off from the Earth. This type of scenario is already discussed by CIA and the Pentagon and not new. Conservatives who hate governmental interventions will have to see much larger interventions in future if they do not accept science now.
