I would have a hard time, though I think these points could all be appropriate responses to the climate crisis.&lt;p&gt;Even better: Try to get elected with that ;-)</text><parent_chain><item><author>NeedMoreTea</author><text>What many seem to forget is 2C or 4C of warming is not an end equilibrium state, it&amp;#x27;s merely an arbitrary date of measurement (end of 21st century) for the track we may irreparably lock in for centuries and millennia.
