July 22 - CIA backs geoengineering study
The Central Intelligence Agency is reportedly funding a scientific study to be carried out by the National Academy of Sciences (NAS) that will investigate whether geoengineering techniques could be used to alter Earth's environment in order to address climate change. Some would say that if the situation has gone so far to require such massive action, then there is little hope for humanity. Read more.

July 8 - Rural vs. city dwellers and carbon emissions
A study carried out in Finland has found city dwellers are responsible for more carbon emissions than their country counterparts. Read more.

July 7 - Amazon deforestation increases

July 4 - Facebook, carbon and coffee
Facebook's 1.1 billion users were on average each responsible for 3.5 kilograms of carbon dioxide emissions; simply by posting and viewing content on the social network last year - using the equivalent to the energy required to make 1 latte coffee or a couple of glasses of wine. Read more.

July 3 - Climate change = cha-ching
Despite a slew of negative impacts caused by climate change, it will also be a huge business opportunity says the UK government and every $1.50 spent on adaptation now could yield $6 in avoided damage. Read more.

Global warming might be making conifers, trees including cypresses and firs, vulnerable to new pathogens as temperatures and rainfall patterns change. A third of the world's conifers are now at risk of extinction. Read more.

July 1 - Australia's climate conditions a "tug of war".
A 'tug of war' between El Niños pushing winds north and a greenhouse gas-warming effect driving winds south has been observed in the Australian and New Zealand region. Read more.
