Scottish Greens' co-convener Patrick Harvie said: "We've always challenged the government to go further in its response to risky climate change".
In a statement released later in the day, Mr. Guterres said that getting there, would require "urgent and far more ambitious action to cut emissions by half by 2030, and reach net zero emissions by 2050".
A stark new report from the global scientific authority on climate change calls on individuals, as well as governments, to take action to avoid disastrous levels of global warming.
Earth is already two-thirds of the way to reaching this disastrous level, and according to co-chair of the IPCC, Panmao Zhai, the planet is already feeling the effects through more extreme weather, rising sea levels, and diminishing Arctic sea.
Increased droughts and poverty brought on by the atmosphere's temperature climbing up to 1.5 degrees Celsius, if greenhouse gas emissions continue at the current rate.
- By 2100, global sea rise levels would be 10cm lower with global warming of 1.5C compared to 2C. Limiting global warming to less than 2ºC will hopefully allow ecosystems and animals to adapt to the gradually rising temperatures.
The summary also said that renewable energy would need to supply 70% to 85% of electricity by 2050 as compared to just 25% now to stay within the 1.5℃ mark.
Martin Keown states his prediction for Liverpool FC v Man City
Manchester City hasn't beaten Liverpool at Anfield in their last 17 meetings in all competitions, dating to May 2003. Martin Keown is backing Liverpool FC to ease to a 3-2 win over Manchester City at Anfield on Sunday evening.
"Limiting warming to 1.5°C is possible within the laws of chemistry and physics but doing so would require unprecedented changes", said Jim Skea, Co-Chair of IPCC Working Group III.
Allowing the global temperature to temporarily exceed or "overshoot" 1.5 °C would mean a greater reliance on techniques that remove Carbon dioxide from the air to return global temperature to below 1.5 °C by 2100. Problematically, the effectiveness of the negative emissions techniques that would be relied upon in such a scenario is unproven on a large scale. "It is now clear that we lost more than 10 years already and the question is about how disastrous will it be in the end".
There is a new report out from the Intergovernmental Panel on Climate Change (IPCC). The report was prepared under the scientific leadership of all three IPCC working groups.
Their concerns meant a pledge to pursue efforts to limit temperature rises to 1.5C was included - after tough negotiations - alongside the commitment to keep them "well below" 2C in the global Paris climate agreement in 2015. Joyashree Roy, professor of economics at Jadavpur University and co-author of the IPCC report said: "We have found that the burden of global warming will fall disproportionately on the poor who are not responsible for the problem if we don't meet 1.5 degree target".
"Any credible pathway to meeting the 1.5 degree scenario must focus on emissions rather than fuel", Katie Warrick, interim chief executive officer of the WCA, said after reviewing a draft of the report.
"In line with our evidence based approach to tackling climate change, we are committed to considering the report carefully, including seeking updated independent, expert advice from the UK Committee on Climate Change on its implications for our targets".
Scientists conclude that global temperatures will climb 2.7 degrees Fahrenheit by 2040.
