In the u Khahlamba/Drakensberg Park World Heritage Site,South Africa,global warming poses a major threat to the preservation of rock art sites.Rock shelters,in particular,are at risk because they are highly dep
Global warmingis the increase in the average temperature of the world's atmosphere and oceans since the preindustrial age. Since 1880, the earth’s average temperature has risen about 1 degree Celsius or 2 degrees Fahrenheit.1 Facts Scientists have three ways tomeasure global warming. Since 1960...
The effects of global warming are already being felt across the globe and countries remain “ill-prepared for risks from a changing climate,” a new report by a United Nations climate panel has found. “We live in an era of man-made climate change,”saidVicente Barros, an emeri...
Hailstorms are dangerous and costly phenomena that are expected to change in response to a warming climate. In this Review, we summarize current knowledge of climate change effects on hailstorms. As a result of anthropogenic warming, it is generally anticipated that low-level moisture and convectiv...
As a result, the malaria projections of the MSM show a decreased length of the malaria season in West Africa. The northern Sahel is no more longer suitable for malaria in the projections and shorter malaria seasons are expected for various areas farther south. In East Africa, higher ...
In recent years, the frequency of extreme weather events has been increasingly associated with global warming, which is often accompanied by high temperature, drought, and low precipitation (IPCC, 2014). Consequently, the frequency and risk of wildfire have significantly enhanced (Abatzoglou and ...
Our results suggest a mean global increase of TFV by ~30%, being highest on continents known to host large dust source areas, such as Australia (60%) and Africa (49%), and lowest in Europe (16%) and South America (13%; Extended Data Fig. 3). These data were added to the global...

In recent decades, with an increase in the availability of satellite observation data, spatially explicit information on the global extent of deforestation and its impact on local temperature is improving16,17,18,19. Consequently, a growing body of literature has studied the impacts of deforestation...
Human activities, especially conversion and degradation of habitats, are causing global biodiversity declines. How local ecological assemblages are responding is less clear—a concern given their importance for many ecosystem functions and services. We a
