across the world's arid regions over the past 30 years through a
process called CO2 fertilisation, according to CSIRO research.
“One byproduct of increased carbon dioxide in the atmosphere and the longer temperate-zone growing seasons accompanying global warming is greater plant growth,” wrote Bjorn Lomborg, director of the Copenhagen Consensus Center

Increase in forest water-use efficiency as atmospheric carbon dioxide concentrations rise
We find a substantial increase in water-use efficiency in temperate and boreal forests of the Northern Hemisphere over the past two decades. We systematically assess various competing hypotheses to explain this trend, and find that the observed increase is most consistent with a strong CO2 fertilization effect. The results suggest a partial closure of stomata1—small pores on the leaf surface that regulate gas exchange—to maintain a near-constant concentration of CO2 inside the leaf even under continually increasing atmospheric CO2 levels.

Cold weather kills far more people than hot weather: (Science Daily)
Cold weather kills 20 times as many people as hot weather, according to an international study analyzing over 74 million deaths in 384 locations across 13 countries.
From Queensland University of Technology:
Summer no sweat for Aussies but winter freeze fatal:(Science Daily)
Australians are more likely to die during unseasonably cold winters than hotter than average summers, research has found. The researchers analyzed temperature, humidity and mortality data from 1988 to 2009 for Adelaide Brisbane, Melbourne, Perth and Sydney to come up with their findings.
The mortal facts from countries all over the world show that more people die in colder weather. Any statistic that suggests climate change is killing people only survives as long as we ignore the number of people saved.
Medical studies rarely show such unanimity. The results stand whether you look at seasonal or daily temperatures, extremes or averages, cold locations versus warm ones, or the trend in flood deaths and droughts. No matter where you live, whether you ail in your heart, or your lungs: You’re less likely to die in warmer weather.
These IPCC and OECD reports are telling us clear as a bell that we cannot ruin the climate with carbon dioxide unless we get a lot more numerous and richer. And they are also telling us that if we get an awful lot richer, we are likely to have invented the technologies to adapt, and to reduce our emissions, so we are then less likely to ruin the planet. Go figure. (link)
