Leading scientists have accused a Republican-led committee of subjecting climate researchers to politically motivated “harassment” amid an increasingly fractious investigation into the activity of the National Oceanic and Atmospheric Administration (Noaa).

Eight key scientific bodies have written to Republican congressman Lamar Smith, chairman of the House committee on science, to warn that the committee’s inquiry into Noaa could have a “chilling effect on the willingness of government scientists to conduct research that intersects with policy-relevant scientific questions”.

The letter added: “Scientists should not be subjected to fraud investigations or harassment simply for providing scientific results that some may see as politically controversial.

“Science cannot thrive when policymakers – regardless of party affiliation – use policy disagreements as a pretext to attack scientific conclusions without public evidence.”

This year will likely be the warmest on record, with the period of 2011-2015 clocking in as the warmest five-year stretch since documentation began, according to the World Meteorological Organization’s (WMO) state of the global climate report. The cause has been put down to man-made climate change driven by rising greenhouse gas emissions, and has been exasperated this year by a particularly strong El Niño event.

“The state of the global climate in 2015 will make history as for a number of reasons,” said the WMO’s secretary general Michel Jarraud, in a statement. “2015 is likely to be the hottest year on record, with ocean surface temperatures at the highest level since measurements began. It is probable that the 1°C [1.8°F] threshold will be crossed. This is all bad news for the planet.”
