The study, published Tuesday in the journal Bioscience, was spearheaded by the ecologists Bill Ripple and Christopher Wolf of Oregon State University, along with William Moomaw, a Tufts University climate scientist, and researchers in Australia and South Africa.

Barnard said the changes shouldn't be seen as "sacrifices", but as a way of "transforming things that we have found stressful".

According to The University of Melbourne climate science and science communication lecturer Dr Linden Ashcroft, the paper paints a grim portrait of our current progress on fighting climate change.

Chinese leader Xi Jinping and French President Emmanuel Macron declared on Wednesday that the Paris climate pact is "irreversible", after the USA formally withdrew from the accord.

The group said that as scientists, they have the "moral obligation to tell it like it is".

Additionally, the "climate crisis" - now rapidly approaching faster than scientists expected - will have consequences for world economies.


Energy. Implement massive conservation practices; replace fossil fuels with clean renewables; leave remaining stocks of fossil fuels in the ground; eliminate subsidies to fossil fuel companies; and impose carbon fees that are high enough to restrain the use of fossil fuels.

In addition to quickly curbing CO2 emissions, the study's authors called on the world's governments to enact policies that dramatically reduce short-lived pollutants like methane, black carbon and hydrofluorocarbons.

Professor William Ripple, a prominentecology professor from Oregon State University in the USA, led the scientists' declaration. Reducing reliance on animal products and shifting towards plant-based diets could reduce emissions of methane and other greenhouse gas emissions that are a byproduct of massive agricultural practices. Our indicators will allow policymakers and the public to better understand the magnitude of this crisis, track progress, and realign priorities to alleviate climate change.

The graphs illustrate how climate-change indicators and factors have changed over the past 40 years, since scientists from 50 nations met at the First World Climate Conference in Geneva in 1979.

In recent months, the grassroots movements Extinction Rebellion, Fridays for Future, and the Global Climate Strike have demanded the world governments declare a climate emergency in order to push the immediate action needed to combat fossil fuel emissions and the warming of the planet. A key aim of the warning is to set out a full range of "vital sign" indicators of the causes and effects of climate breakdown, rather than only carbon emissions and surface temperature rise.

Humanity's expanding numbers, appetites and activities have fuelled the problem, originally in the developed world but now on a global scale.


Major powers expressed regret and concern after Trump went ahead with the pullout despite mounting evidence of the reality and impact of climate change.

"It's important when presenting these results to look at some positives, and one of the more positive things that we've pulled out of this data is that there is now a slight decline in birth rates at a global level".

"Ice is rapidly disappearing as shown by declining trends in minimum summer Arctic sea ice, Greenland and Antarctic ice sheets, and glacier thickness. All of these rapid changes highlight the urgent need for action". "We can take steps to address the climate emergency".

"I don't think the Alliance [of World Scientists] is actively endorsing, discouraging or encouraging civil disobedience", Dr Newsome said.
