Climate change remains a taboo subject for many people including the president of the United States, but at the recent Porto Climate Change Leadership Summit the keynote speaker, former Vice-President Al Gore, reiterated the alarming scientific evidence for global warming.
Meanwhile, a new analysis claims that the five largest oil and gas companies in the world spend nearly $200 million annually in lobbying to delay, control or block policies to tackle climate change. Millions of dollars are being spent on targeting Facebook and Instagram ads by the global oil giants and related organisations to promote the benefits of increased fossil fuel production, according to the report published by InfluenceMap.
