New maps help decision-makers factor albedo into tree-planting plans Albedo can cause large reductions to the climate benefit of tree planting – but new science helps identify locations with greatest climate-cooling potential

Tree-planting is always good, right? Well, it turns out that a tree planted in the wrong place can actually have a negative impact on the climate. That’s why a research team with scientists from The Nature Conservancy developed maps to help with strategic reforestation for maximum benefit!

There are myriad examples of prey naivete, enemy release, biotic resistance, mutualisms etc, that demonstrate the importance of evolutionary context in species interactions.

This is why species origins matter. #bioinvasions

How bad will it be? Catastrophic.

Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come.

But, this is the WH's *proposed* budget.
