The evidence for human-induced climate change is irrefutable and includes an average surface temperature rise of 1.62 degrees Fahrenheit since the late 19th century; the warming of the ocean by 0.4 degrees since 1969; a loss of 286 billion tonnes of ice per year from 1993 to 2016 in Greenland; glacial retreat
; decreased snow cover, extreme weather events, ocean acidification and about an 8 inch rise in sea level in the last century .
Release date- 20082019 - Under a pilot project being spearheaded by the Swiss Agency for Development and Cooperation (SDC), a team of experts - including civil and environmental engineers from EPFL - are studying methods to help protect a region of the Andes Mountains threatened by glacial retreat
The adverse and dire effects of rapid climate change to our planet include extreme weather conditions (such as longer and hotter heat waves, more frequent droughts, heavier rainfalls, and more powerful hurricanes), shrinking ice sheets, glacial retreat
, rising sea surface temperatures and sea levels, ocean acidification, and shifts in flower/plant blooming times.
According to their oral traditions, both the Sauk and Meskwaki tribes were living in Canada 12,000 years ago at the time of the last glacial retreat
. Many centuries later, they were displaced from their Canadian home by the Iroquois.
, first photographed in 1906 by Vittorio Sella who accompanied HRH Prince Luigi Amedeo of Savoy, Duke of the Abruzzi on his expedition to the area, is now disturbingly apparent.
Summary: TEHRAN (FNA)- Glacial retreat
in the Canadian Arctic has uncovered landscapes that haven't been ice-free in more than 40,000 years and the region may be experiencing its warmest century in 115,000 years.
Tsunamis and avalanches aren't the only hazards caused by glacial retreat
. Melting mountain glaciers also can leave large lakes at high altitudes; these lakes can then suddenly drain, cascading down slopes.
He explains how the fauna appeared in the first place, and makes the massive timeline between the glacial retreat
and the appearance of humans comprehensible.
snowfall do not contradict the observations of glacial retreat
The conceptual model for glaciation-deglaciation implies that recharge of oxygenated water occurs: (a) during interglacial periods, (b) during the period of glacial advance in unglaciated regions in front of the advancing ice sheet, and (c) during glacial retreat
in unglaciated regions and beneath the retreating ice sheet.
Our study shows there may be other underappreciated, unanticipated effects of glacial retreat
