'Feel good' factor not CO2 boosts global forest expansion

'Feel good' factor not CO2 boosts global forest expansion

Science
Forests are increasing around the world because of rising incomes and an improved sense of national wellbeing say researchers.The authors refute the idea that increasing levels of CO2 in the atmosphere are the key cause of the spread of trees. As countries become better off, farmers focus on good quality soils and abandon marginal lands, the authors say.As a result, trees are able to rapidly reforest these deserted areas.The study highlights the fact that between 1990 and 2015 forest growing stock increased annually by 1.31% in high income countries and by 0.5% in middle income nations, while falling by 0.72% in 22 low income countries. Several global climate models have attributed this change to what's termed CO2 fertilisation -...
Unintended weight loss identified as second highest cancer risk factor

Unintended weight loss identified as second highest cancer risk factor

Health
April 10 (UPI) -- When a person experiences an unintended weight loss, it is the second-highest predictor for some forms of cancer, according to an analysis of studies.Researchers at the universities of Oxford and Exeter analyzed the findings of 25 studies, incorporating data from more than 11.5 million patients collected between 1994 and 2015. They found that weight loss was linked with 10 types of cancer: prostate, colorectal, lung, gastro-esophageal, pancreatic, non-Hodgkin's lymphoma, ovarian, myeloma, renal tract and biliary tree.Their analysis was published Monday in the British Journal of General Practice.Unintended weight loss in people older than 60 exceeded the 3 percent risk threshold for urgent investigation, according to guidelines by Britain's National Institute for Health Re...
