What will life be like if global average temperatures increase over 4 degrees Celsius (7.1 degrees Fahrenheit)? What will life be like if sea levels increase 8 meters (26 feet)? What if both happen? The Entity science fiction book series (www.theentity.us) takes the reader on a one-thousand-year struggle of humanity to save Earth as a habitable planet. The series begins with three novels in the years 2147, 2647 and 3147. It takes one-thousand years to see the disastrous effects of climate collapse. Far more is at risk than losing coastal cities and land. The effects of climate change will upend everyone’s life. Will institutions survive? Will governments fail? Will democracy endure? Will capitalism prevail? Will your standard of living perish? Will humankind survive? Does humanity have the political will to solve the climate crisis? Are the adversary’s technology, the universal laws of thermodynamics, or humankind itself? In the science fiction series, one relentless antagonist is climate change with a second antagonist emerging later in the series. Can humanity survive these two powerful adversaries? In David A. Collier’s debut novel, The Entity: 2147, the mysterious entity arrives on Earth offering a solution to an Earth ravaged by heat and flood. But humanity must overcome its greatest obstacle: itself. The burden of salvation falls on the shoulders of the Hickory family as fractured nations, ignorant governments, and ravenous media grapple with the entity’s arrival. In the second novel, The Entity: Climate Change 2647, the entity returns to Earth to find more climate destruction and human chaos. The planet’s climate shifts have triggered mass migration, war, disease, famine, and the collapse of almost seventy governments. The story takes readers on a journey of humanty’s fight for survival through the experiences of the Paris family. The story ends with a unique solution for the Paris family—one of hope and eternal love.
