A new way to fight climate change: Trap carbon dioxide in volcanic rocks

Climate change refers to the fluctuation of the climate system caused by the energy entering and leaving Earth. The greenhouse effect, which refers to how greenhouse gases (GHGs) act like a blanket and prevent the loss of Earth’s heat to space, has occurred naturally throughout Earth’s history. However, since the Industrial Revolution, human activities have […]

Lightning increasing with global warming

A new analysis of climate change models predicts a 50 percent increase in lightning strikes across the United States during this century as a result of warming temperatures associated with climate change. University of California, Berkeley, climate scientist David Romps and his colleagues looked at predictions of precipitation and cloud buoyancy in 11 different climate […]

Mammals may shrink with warming climate

Mammal body size decreased significantly during two ancient global warming events, say paleontologists from the University of Michigan who believe that similar changes are possible in response to human-caused climate change. Researchers have long known that mammals became much smaller during a period of warming called the Paleocene-Eocene Thermal Maximum (PETM), about 55 million years […]

New evidence for climate change creating modern humans

While archaeological and genetic evidence suggest that Homo sapiens originated in Africa around 200,000 years ago, it is more difficult to identify when modern human behaviors emerged. Intriguingly, recent archaeological excavations in southern Africa have shown that technological innovation, linked to the emergence of culture and modern behavior, took place relatively suddenly on more than […]

Tree plumbing stress approaching tipping point

The hydraulic system of trees is so finely-tuned that predicted increases in drought due to climate change may lead to catastrophic failure in many species. That’s according to a new study that found many plants around the globe are already operating at the top of their drought-stress safety threshold. The new work is based on […]

Wild Arabica coffee facing extinction

Scientists who have predicted the possible extinction of wild Arabica coffee (Coffea Arabica) within 70 years say urgent conservation measures are needed to future-proof Arabica’s genetic diversity and ensure the long-term sustainability of Arabica coffee production. The new insights into the second most traded commodity after oil have been compiled by scientists in the UK […]
