Sydney, June 1, 2017 (dpa/NAN) Australian climate scientists on Thursday released a global database showing rise in greenhouse gases.

The scientists in the Geoscientific Model Development journal  showed the world’s “most comprehensive” record of greenhouse gas readings as evidence of humans’ involvement in climate change.

The research includes a worldwide database charting 43 gases that contribute to global warming over 2,000 years by combining greenhouse gas measurements from dozens of laboratories and weather stations from around the world.

Comparing the data to air bubbles trapped in ancient ice cores, as well as compacted snow, scientists from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the University of Melbourne found carbon dioxide, methane and nitrous oxide at higher levels than they have ever been over the last 800,000 years.

The research also showed a significant and continuous rise in greenhouse gas levels since the Industrial Revolution, then again in the 1950s.

“These observations clearly show the relentless and near-continuous rise of some of the most important greenhouse gases like carbon dioxide, methane and nitrous oxide since 1750,” David Etheridge, the co-author and principal research scientist said.

Lead author, Malte Meinhausen, from the Australian-German Climate and Energy College at the University of Melbourne, said the research confirmed the “concerning picture” already known to scientists.

“Ggreenhouse gases are rising relentlessly,” he said. (dpa/NAN)
