Lately a new thing has started: climate fiction – cli fi. Cli fi writers have a strange notion that humanity could render Earth uninhabitable. Our recent climate has been interglacial. We’re still in an ice age, the Quaternary (2.6 Mya-present), the latest of the five major glaciations in Earth’s history. The Holocene, the latest interglacial, has lasted about 11 thousand years. There has been life on Earth continuously throughout all the glaciations.  Humans don’t really have the ability to destroy life on the planet.  Human life, maybe. Human civilization, certainly.

My WiP, IX New Millennium, is a strange kind of dystopia. The environment has been restored to a pristine state and humanity all but erased. This was done by a deliberate act of genocide perpetrated by the Young, a tiny cadre (34 in all) of gene-modified humans who value the biosphere above humanity. They’ve kept normal humans around to do the reclamation work but plan to eliminate them when remediation is complete.

Decades before the genocide Ignatius Ryan, a Jesuit priest, was banished to the future in cryosleep by his Church due to a theological controversy. After a millennium in a spacecraft on a cometary orbit, he arrives to an Earth with a rich biosphere but devoid of compassion. Grace, Ignatius’ companion AI , hacks into a network of military satellites and fires a laser at the ground to make an impression on the normal human survivors Ignatius meets. This draws the attention of the hidden city of S’Loo and its rulers, who see Ignatius as a threat and want him dead.

With Morna, a survivor who seduces him, Ignatius must struggle against the Young and their acolytes to survive and prevent the final extinction of humanity.
