Greenhouse Gas concentrations hit record highs once again

The concentration of heat-trapping greenhouse gases in the atmosphere reached a new record level last year. This is part of an upward trend with no end in sight, according to the World Meteorological Organization (WMO). The UN agency’s latest Greenhouse Gas Bulletin compares the gas concentration levels with the previous year and with preindustrial levels. It warns that the rising concentration of greenhouse gases in the atmosphere will lead to a rise in temperature, extreme weather conditions, and a rise in sea levels.
