"We know without any doubt that our climate is changing and our weather is becoming more extreme due to human activities such as the burning of fossil fuels," said Michel Jarraud, the head of the World Meteorological Organization (WMO) that released a report on the issue on Tuesday.
"We must reverse this trend by cutting emissions of CO2 and other greenhouse gases across the board," Jarraud said in a statement.
"We are running out of time," he warned.
Concentrations of carbon dioxide (CO2), methane and nitrous oxide all broke fresh records in 2013, said the report.
Global concentrations of CO2, the main culprit in global warming, soared to 396 parts per million last year, or 142 percent of pre-industrial levels — defined as before 1750.
That marked a hike of 2.9 parts per million between 2012 and 2013 alone — the largest annual increase in 30 years, according to the Greenhouse Gas Bulletin.
The report comes ahead of a September 23rd summit called by UN Secretary General Ban Ki-moon to try to build momentum for change ahead of talks in Paris next year aimed at forging a historic climate deal that will take effect in 2020.
The UN is seeking to limit global warming to two degrees Celsius (3.6 degrees Fahrenheit) over pre-Industrial Revolution levels, but scientists say current emission trends could hike temperatures to more than twice that level by century's end.
