Almost 200 countries have signed up to the Paris climate accord, which aims to keep global warming below 2 degrees Celsius (3.6 degrees Fahrenheit), ideally no more than 1.5 C (2.7 F), by the end of the century compared to pre-industrial times.

The 3,000-page report “provides an unprecedented degree of clarity about the future of our planet, and the need to reduce – and ultimately eliminate – our emissions of greenhouse gases,” said Zeke Hausfather of the Breakthrough Institute, a global environmental research center.

Code red for humanity’: UN report gives stark warning on climate change, says wild weather events will worsen

·3 min read

Hundreds of top scientists released a devastating report Monday on the danger that human-caused climate change poses to the world.

Calling it “code red for humanity”  the landmark report was released in Geneva by the United Nations


The report, which calls climate change clearly human-caused and “unequivocal,” makes more precise and warmer forecasts for the 21st century than it did last time it was issued, in 2013.“If this IPCC report doesn’t shock you into action, it should,” said Helen Mountford of the World Resources Institute, a research nonprofit organization. “The report paints a very sobering picture of the unforgiving, unimaginable world we have in store if our addiction to burning fossil fuels and destroying forests continues. One of the most striking takeaways is that we may reach 1.5°C of warming a decade earlier than the IPCC had previously found.”



“It is more likely than not” that the world’s temperatures will increase to 1.5C above pre-industrial levels sometime over the next 20 years, and 2C by 2100 – the report, authored by 234 scientists in 66 countries, published on Monday said. Temperatures currently stand at around 1.2C above pre-industrial levels.”

Weather extremes, fossil fuel pollution cost US $240 billion: study

“The evidence is undeniable: the more fossil fuels we burn, the faster the climate continues to change,”

“Costs to human health from air pollution caused by fossil fuels averaged $188 billion a year over the past decade, it estimated, while losses from weather extremes such as droughts, heat waves and floods averaged $52 billion.”

“the $240 billion costs, equivalent to 1.2 percent of U.S. gross domestic product”

“The combined cost of extreme weather and pollution from fossil fuels would climb to $360 billion a year in the next decade, the study said.”

How much air pollution comes from cars?


“According to the EPA, motor vehicles collectively cause 75 percent of carbon monoxide pollution in the U.S.”


“The Environmental Defense Fund (EDF) estimates that on-road vehicles cause one-third of the air pollution that produces smog in the U.S., and transportation causes 27 percent of greenhouse gas emissions.”

Climate Change Investing: The Greatest Opportunity In History


“So, what can we do? Is civilization doomed? My answer is “Absolutely not!”

The issues pointed out in Limits to Growth and backed up by subsequent experimental results offers humanity the kind of opportunity that exceeds any economic potential ever experienced in the historical record.”

“Complacent optimism is the feeling of a child waiting for presents. Conditional optimism is the feeling of a child who is thinking about building a treehouse. “If I get some wood and nails and persuade some other kids to help do the work, we can end up with something really cool.

Think of the fortunes made during the Industrial Revolution – fortunes that exist even to the present day”
