Scientists introduced Wednesday that 2019 now ranks because the second hottest 12 months globally. It is available in second to 2016 by lower than 0.75°F (or about 0.04°C). 5 of the warmest years in recorded historical past have occurred since 2015.

World common temperatures in 2019 had been 1.71°F (0.95°C) above the 20th century common, in line with a brand new research by the Nationwide Oceanic and Atmospheric Administration (NOAA) and NASA. A number of months all year long noticed their highest world temperatures in recorded historical past, together with June, when many European international locations recorded record-breaking warmth. The 12 months was additionally the most popular on report for Alaska, the place wildfires burned all through the state over the summer time.

Scientists additionally introduced Monday that ocean temperatures are hotter than they’ve ever been. “We’re heating the oceans at the moment by the equal warmth of 5 Hiroshima bombs each second, day and night time, 365 days a 12 months,” says John Abraham, professor of thermal sciences on the College of St. Thomas, who co-authored the research on oceanic temperature rise.

Oceanic temperature enhance will result in extra extreme and frequent pure disasters like hurricanes; will enhance sea ranges; and may completely harm animal life, Abraham tells TIME.

A 2018 research by the Intergovernmental Panel on Local weather Change, the United Nation’s local weather physique, beforehand warned {that a} world temperature rise of 1.5°C above preindustrial ranges might have disastrous penalties.

“Temperatures will proceed to extend and break information for many years to come back—till world emissions attain web zero CO2,” says Piers Forster, professor of local weather physics on the Priestley Worldwide Centre for Local weather on the College of Leeds, in an emailed assertion to TIME. “So we’d like to ensure our infrastructure and our meals methods can dwell with this new regular.”
