The Scottish Government said it will look at targets again in the wake of the IPCC report.

'Because I can give you reports that are fabulous and I can give you reports that aren't so good, ' he said.

"This report is not a wake-up call, it is a ticking time bomb", said Gro Harlem Brundtland, Acting Chair of The Elders in a statement.

The IPCC is the leading world body for assessing the science related to climate change, its impacts and potential future risks, and possible response options.

"We saw a really complicated discussion", Arias Canete said of the compromise on Tuesday, which 20 nations supported, four voted against and four abstained from.

"E$3 ven with erroneous attribution of extreme weather/climate events and projections using climate models that are running too hot and not fit for objective of projecting 21st century climate change, the IPCC still has not made a strong case for this massive investment to prevent 1.5C warming", she said on her Climate Etc. blog.

The Trump administration has dismantled emissions reduction policies domestically, and vowed to ditch the Paris treaty on attempting to reduce greenhouse gas emissions worldwide. "What we've done is said what the world needs to do", Imperial College London's Jim Skea, cochair of the IPCC panel, said at a press conference. This rise is already causing rising sea levels and more extreme weather, and the figure is going up by around 0.2 degrees per decade.

The IPCC report, however, shows that global warming impacts have come sooner and hit harder than predicted.

These are just a few examples taken from a depressingly long list of climate change threats that would be made significantly more risky if the temperature were to rise by 2°C or beyond by the end of the century. Obviously, this would have a major knock-on effect for humans who require them to produce our food.

European Union countries have agreed to pursue a 35 percent cut in vehicle emissions by 2030, as part of global efforts to reduce carbon dioxide emissions and limit global warming.

Hurricane Michael left path of destruction, isn't done yet
A scary note in this advisory from the Hurricane Center is that "some additional strengthening is possible before landfall". The neighbor said all the docks in the area are destroyed, the roads are impassable and everyone is stuck in their homes.

Federer fires out warning to Kyrgios
The Croatian saved two break points at 3-3 in the second set and claimed three of the first four games in the decider. It is the third successive year in which the Australian has gone out of the tournament in controversial fashion.

Trump welcomes Kanye West to the Oval Office
He's a smart cookie. "Only after 2024", West added. " I love this guy ", Kanye declared in the Oval Office. West said that he brought a newly designed hat that simply stated: "Make America Great".

In order to reach this, society will need to make "unprecedented" changes including closing hundreds of coal-fired power stations and rapidly switching to renewable energy.

A new United Nations report warns that much of the world will be screwed by the year 2040 unless we basically reduce carbon emissions to zero.

Ninety-one authors and review editors from 40 countries prepared the IPCC report in response to an invitation from the United Nations Framework Convention on Climate Change (UNFCCC) when it adopted the Paris Agreement in 2015.

They're calling for "rapid, far-reaching and unprecedented changes" across society to prevent world temperatures from rising by two degrees Celsius.

In the Paris accord, 197 countries agreed to the goal of holding global temperatures "well below" 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit it to 1.5 degrees Celsius.

The transport sector is the only major industry in the European Union in which greenhouse gas emissions are still rising. Since the mid-1800s the climate has already warmed by 1C. For instance, by 2100, global sea level rise would be 10 cm lower with global warming of 1.5°C compared with 2 °C.

What does the report say?

To illustrate how far off this is, Carbon dioxide levels rose about 3 per cent a year between 2000 and 2013, and by about 0.4 per cent a year between 2013 and 2016.

The report underlines how even the smallest increase in the base target would worsen the impact of recent natural disasters. "Governments do not formally endorse specific findings presented by the authors".
