Evidence increasingly suggests that as climate warms, some plant, animal and human populations may move to preserve their environmental temperature. The distances they must travel to do this depends on how much cooler nearby surfaces temperatures are. Because large-scale atmospheric dynamics constrain surface temperatures to be nearly uniform near the equator, these displacements can grow to extreme distances in the tropics, even under relatively mild warming scenarios. Here we show that in order to preserve their annual mean temperatures, tropical populations would have to travel distances greater than 1000 km over less than a century if global mean temperature rises by 2 °C over the same period. The disproportionately rapid evacuation of the tropics under such a scenario would cause migrants to concentrate in tropical margins and the subtropics, where population densities would increase 300% or more. These results may have critical consequences for ecosystem and human wellbeing in tropical contexts where alternatives to geographic displacement are limited.

Hype for the Future 11A: Festival Populations
novaTopFlex is often interested in festivals and events in excess of 100,000 attendance. Such events of interest include the Ohio State Fair with nearly 1,000,000, the Quarter Horse Congress with around 650,000, the Ohio Sauerkraut Festival with around 400,000, the Voices of America Country Music Festival with potentially over 100,000, and possibly even Country Jam USA and the Hinterland Music Festival in Eau Claire, Wisconsin, and Saint Charles, Iowa, respectively. Apart from the major […]https://novatopflex.wordpress.com/2025/11/11/hype-for-the-future-11a-festival-populations/

Climate Change Driving Mass Bird Deaths in the Amazon
A recent #study has revealed that even in the most isolated parts of the #Amazon, bird #populations are collapsing due to #climatechange. Research published in Science Advances found that a 1°C increase in temperature led to a 63% drop in bird survivability, proving that climate change is pushing avian species towards #extinction. Avoiding deforestation-linked products like #palmoil and #meat is crucial in the fight for their survival. As is calling out corporate greenwashing, be #Vegan and #BoycottPalmOil #Boycott4Wildlife

A team of environmental scientists from the Instituto Nacional de Pesquisas da Amazônia, Michigan Technological University, and the University of Oregon examined decades of bird population data from Brazil’s Biological Dynamics of Forest Fragments Project. They found that bird numbers have steadily declined, with some species even disappearing entirely.
For years, researchers were unsure why birds were vanishing from pristine environments untouched by human development. This study provides clear evidence that climate change is making forests uninhabitable, even for species that have survived in stable, humid ecosystems for millennia.
Heat stress and climate instability
The study found that rising temperatures are disrupting forest ecosystems, creating longer dry seasons, shifting plant and animal populations, and removing essential food sources.
Bird species rely on stable seasonal cycles to build nests, lay eggs, and forage for food for their young. However, as global temperatures rise, their food sources peak too early or disappear entirely. Many chicks are now hatching into a world where food no longer exists, leading to mass starvation and long-term population collapse.
Climate change aggravates bird mortality in pristine tropical forests, Science Advances, Jared D. Wolfe et al. (2025). DOI:10.1126/sciadv.adq8086Global implications
While this study focused on the Amazon, its findings have global implications. Bird populations in rainforests worldwide are experiencing similar declines due to climate instability, habitat destruction, and resource depletion.

3. Supermarket sleuthing: Next time you’re in the supermarket, take photos of products containing palm oil. Share these to social media along with the hashtags to call out the greenwashing and ecocide of the brands who use palm oil. You can also take photos of palm oil free products and congratulate brands when they go palm oil free.
