European colonization of the Americas resulted in the killing of so many native people that it transformed the environment and caused the Earth’s climate to cool down, new research has found. Settlers killed off huge numbers of people in conflicts and also by spreading disease, which reduced the indigenous population by 90% in the century following Christopher Columbus’s initial journey to the Americas and Caribbean in 1492. This “large-scale depopulation” resulted in vast tracts of agricultural land being left untended, researchers say, allowing the land to become overgrown with trees and other new vegetation. The regrowth soaked up enough carbon dioxide from the atmosphere to actually cool the planet, with the average temperature dropping by 0.15C in the late 1500s and early 1600s, the study by scientists at University College London found. “The great dying of the indigenous peoples of the Americas resulted in a human-driven global impact on the Earth … [Read more...] about European colonization of Americas helped cause climate change

BRITISH workers could miss as many as 33 days of work a year as a result of climate change, a new study has found. The research also found that workers in developing countries could lose a maximum of 94 days a year, with nations in Southeast Asia being most severely affected. Publishing in the Journal of Cleaner Production, the team of researchers from the Chinese Academy of Sciences began their work with a survey of how many days of work high temperatures caused people to miss in 2016. In developed countries such as the UK and the US, the average worker currently loses 3.5 days of work a year as a result of 'heat stress,' which covers sickness caused by excessive heat. In the developing world this average is 6.6 days, yet the researchers calculated that this is set to rise under all four of the main climate-change scenarios set out by the Intergovernmental Panel on Climate Change (IPCC). If the worst-case scenario of a 4C rise by 2100 is realised, people in the developed … [Read more...] about Britons could miss 33 days of work a year due to global warming
0 Have your say As much of the country suffers under another week of sweltering temperatures, Westminster’s Environmental Audit Committee has issued a stark warning: heat-related deaths will treble by 2050 as a result of a warming climate. A shocking 7,000 people will die in the UK each year from the impacts of heat unless government acts on the dangers of climate change.The committee’s focus on adaptation in its recommendations reflects the grim reality that global warming is not some distant threat, but is happening now, and we must prepare to deal with the consequences of living in a world made warmer by human actions. News of a rising death toll from climate disasters around the world that have made the headlines all too often this summer, from prolonged heatwaves in Canada and Japan, to flash floods in Laos and Cambodia, and raging wildfires in Greece and Sweden, help this reality to sink in.

Doyle Rice USA TODAY Published 5:08 p.m. UTC Jul 23, 2018 Rising temperatures due to human-caused climate change could lead to increasing suicide rates in the U.S. and Mexico, a study released Monday suggests. By comparing historical temperature and suicide data going back decades, researchers found a strong correlation between warm weather and increased suicides, according to new research published in Nature Climate Change, a peer-reviewed British journal. Researchers have known for centuries that conflict and violence tend to peak during warmer months. "Now we see that in addition to hurting others, some individuals hurt themselves," said Solomon Hsiang, study co-author from the University of California, Berkeley. "It appears that heat profoundly affects the human mind and how we decide to inflict harm." The study found climate change could lead to between 9,000 and 44,000 additional suicides across the U.S. and Mexico by 2050. … [Read more...] about Global warming risk: Rising temperatures from climate change linked to rise in suicides
