How Native American depopulation impacted ecology

Native American depopulation

There is little dispute that in the wake of European colonists’ arrival in the New World, Native American populations were decimated by disease and conflict. But when it comes to the timing, magnitude, and effects of this Native American depopulation — it depends on who you ask. Many scholars claim that disease struck the native population shortly after their first […]

Tropical groundwater resources resilient to climate change

Tropical groundwater may prove to be a climate-resilient source of freshwater in the tropics as intense rainfall favours the replenishment of these resources, according to a new study published in Environmental Research Letters. As climate observations show that global warming leads to fewer but more intense rainfalls, a clearer understanding of how these sources are replenished is crucial for developing […]

Antarctic Ice Sheet Mass gains greater than losses

Antarctic Ice Sheet

A new NASA study on the Antarctic Ice Sheet says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers. The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that […]

Ozone Hole Over Antarctica

Ozone Hole Over Antarctica

The ozone layer is a protector of the earth from ultraviolet radiation from the sun.  According to reports the ozone layer is getting smaller over Antarctica.  The scientists are using satellites and sensors to get information on the measurements of the ozone layer. Since the early 20th century when the emissions of chemical substances called halo-carbons the ozone layer has […]

A warmer world will be a hazier one

Aerosols, tiny solid and liquid particles suspended in the atmosphere, impact the environment by affecting air quality and alter the Earth’s radiative balance by either scattering or absorbing sunlight to varying degrees. What impact does climate change, induced by greenhouse gases (GHGs), have on the aerosol “burden”–the total mass of aerosols in a vertical column of air? Past research done […]

Climate change helps Alaskan grow organic food on the tundra

Between fighting wildfires and rerouting the Iditarod, Alaska has had a tough time with climate change. But at least there’s one good outcome: local food. In Bethel, a town in southwestern Alaska, farmer Tim Meyers is taking advantage of rising temperatures to grow food in the previously inhospitable tundra. NPR reports: At the 15-acre organic farm, which has been operating for more […]

10 Foods Predicted to Go Extinct

How Climate Change Could Affect Our Diet  Climate change and a shopping list? At first glance, it seems just a wrong correlation. Well, it is not! Climate change is already affecting our present and it will heavily influence our future. The extreme weather conditions brought by climate change are progressively increasing the risk of drought, floods, heat waves and wildfires, […]

Climate risk to inflexible penguins’ chicks

Crested and rockhopper penguins are threatened by climate change – but this time the penguins could be at risk because they cannot change their own ways. Evolution has left them with a rigid parenting strategy, probably well adapted for climate conditions so far. But as temperatures rise, conditions change and food supplies become precarious, the inflexible roles of male and female […]
