Future of the human climate niche

When the prestigious Proceedings of the National Academy of Sciences (PNAS) participate in disseminating Global Warming Hoax propaganda and demagoguery!



"Significance We show that for thousands of years, humans have concentrated in a surprisingly narrow subset of Earth’s available climates, characterized by mean annual temperatures around ∼13 °C. This distribution likely reflects a human temperature niche related to fundamental constraints. ... Absent climate mitigation or migration, a substantial part of humanity will be exposed to mean annual temperatures warmer than nearly anywhere today.
Abstract
All species have an environmental niche, and despite technological advances, humans are unlikely to be an exception. ... We show that in a business-as-usual climate change scenario, the geographical position of this temperature niche is projected to shift more over the coming 50 y than it has moved since 6000 BP. ...  As the potentially most affected regions are among the poorest in the world, where adaptive capacity is low, enhancing human development in those areas should be a priority alongside climate mitigation."

These "fundamental constraints" are mere conjecture and speculation than anything else! This is not science!!! As a minimum this negates evolution and the adaptability of nature!

Do these dim witted, biased scientists even realize that probably more than 1 billion humans were lifted out of poverty by market economies over the last 30-40 years alone! That many countries in Africa are the next economic tigers etc. Thus to claim that "poorest in the world, where adaptive capacity is low" is an insult to intelligence and common sense!
