The past eight years are the warmest on record according to a new UN report.
It's release is to coincide with the COP27 conference in Egypt.
The World Meteorological Organisation says the last eight years having record high temperatures is fuelled by greenhouse emissions and accumulated heat.
It says the rate of sea level rise has doubled since 1993 - and in the past two years alone it increased by 10 millimetres.
The WMO - which is a UN body - says this year has taken a big toll on glaciers in the Alps, and in Greenland.
The global temperature is estimated to be 1.15-degrees above the pre-industrial age - which is the barometer for climate change.
A previous UN report said there's no credible pathway to keeping global temperature rises to within 1.5-degrees - and with current policies, we are on course for a 2.8-degree rise.
That will bring more extreme weather including heatwaves, storms and flooding.
