Global sea surface temperature for April were the warmest on record, reaching 68.97 degrees Fahrenheit, according to the EU's Copernicus Climate Change Service.
That means 13 straight months of record heat.
Air temperatures were also the warmest on record as the planet reached its 11th warmest month — April saw an average surface air temperature of 59.05 degrees Fahrenheit, 1.21 degrees Fahrenheit above the 1991 to 2020 average for April, according to the report.
The Paris Agreement aims to limit global warming to 1.5 degrees Celsius (2.74 Fahrenheit) higher than pre-industrial levels.
Hayley Fowler, a climate scientist at Newcastle University, said the data shows the world is perilously close to breaching the 2015 Paris Agreement's goal.
"At what point do we declare we've lost the battle to keep temperatures below 1.5? My personal opinion is we've already lost that battle, and we really need to think very seriously about keeping below 2C and reducing our emissions as fast as we can," she said.
Greenhouse gas emissions from burning fossil fuels are suspected as the main cause of climate change. In recent months, the natural El Nino phenomenon, which warms the surface waters in the eastern Pacific Ocean, has also risen in temperature.
Scientists have already confirmed that climate change caused some specific weather extremes in April, including a heatwave in the Sahel region of Africa and is linked to potentially thousands of deaths.
"The fact that all this heat is going into the ocean, and in fact, it's warming in some respects even more rapidly than we thought it would, is a cause for great concern," Prof. Mike Meredith from the British Antarctic Survey told the BBC.
"These are real signs of the environment moving into areas where we really don't want it to be and if it carries on in that direction the consequences will be severe."
