Reforestation to capture carbon could be done much more cheaply, study says

  By Liz Kimbrough, via Mongabay   Trees are allies in the struggle against climate change, and regrowing forests to capture carbon may be cheaper than we thought. According to new research published in Nature Climate Change, a strategic mix of natural regrowth and tree planting could be the most cost-effective way to capture carbon. Researchers analyzed reforestation projects in 138 low- and middle-income countries to compare the costs of different […]

Planting trees in grasslands won’t save the planet – rather protect and restore forests

    By Susanne Vetter, Rhodes University   Tree planting is one of the nature-based solutions being used to offset greenhouse gas emissions. Trees absorb atmospheric carbon dioxide. Many of these tree planting projects target Africa’s rangelands (open grasslands or shrublands used by livestock and wild animals). They include agroforestry initiatives such as the Great Green Wall in the Sahel, or commercial timber plantations that double as carbon offset projects. […]

Fossil beetles found in a Botswana diamond mine help us to reconstruct the distant past

    By Sandiso Mnguni, University of the Witwatersrand   When most people think of fossils they probably picture bones. But there’s much more to the global fossil record: plants, shells, minerals and insects. The study of fossil insects is called palaeoentomology.

Rhinos can’t sweat, making them vulnerable to overheating: global warming could wipe them out in southern Africa

    By Timothy Randhir, UMass Amherst   Southern Africa is home to 22,137 of the world’s 23,432 white and black African rhinos. But they’re facing grave threats because of a warming planet. Now, the first study of how climate change affects rhinos in southern Africa has found that they will cease to exist in the region’s national parks by 2085 if the world takes the worst-case scenario climate change […]
