Rapid, far reaching and unprecedented changes to all aspects of society are needed if global warming is to be limited 1.5 degrees, according to a new assessment by the Intergovernmental Panel on Climate Change.
The date, which falls within the lifetime of many people alive today, is based on current levels of greenhouse gas (GHG) emissions.The report makes it clear that climate change is here already - and that what comes next could be even worse, unless urgent global action is taken.
By the end of the century, if warming stops at 1.5 degrees, the sea level rise may be almost four inches lower than if it stops at 2 degrees. "Coral reefs would decline by 70-90 percent with global warming of 1.5°C, whereas virtually all ( 99 percent) would be lost with 2°C", as the IPCC related in the release.
"Even the scientists were surprised to see how much science was already there and how much they could really differentiate and how great are the benefits of limiting global warming at 1.5 compared to 2", Thelma Krug, vice-chair of the IPCC, told Reuters in an interview.
Some of the world's top climate scientists have concluded that global warming is likely to reach risky levels unless new technologies are developed to remove greenhouse gases from the atmosphere.
The IPCC's models emphasize the need for people to change their lifestyle and consumption patterns to more sustainable alternatives, specifically in areas they can control, like modes of transportation, the buildings they inhabit and their dietary preferences.
Keeping the 1.5C target would keep the global sea level rise 3.9 inches lower by 2100 than a 2C target, the report states. Any additional emissions would require removing Carbon dioxide from the air.
It was Trump's first reaction to the report, which says that the Earth surface has warmed one degree Celsius (1.8 degrees Fahrenheit) and is on track toward an unliveable 3C or 4C rise.
They're calling for "rapid, far-reaching and unprecedented changes" across society to prevent world temperatures from rising by two degrees Celsius.
- It will require a huge ramp-up in renewables so they generate 70-85% of electricity supplies by 2050, while coal power's share of the mix tumbles to nearly nothing.
It also lays out courses of action that could be taken to keep the rise in check.
At 1.5 degrees, the authors predict the Arctic Ocean will be free of sea ice once per century. It concludes that if greenhouse gas emissions continue at the current pace, coastal flooding could become intense and droughts severe by 2040.
