For years, a worst-case climate scenario served as a stark warning of what could happen if the world failed to curb fossil fuel use. A temperature rise of more than 4 degrees Celsius (7.2 degrees Fahrenheit) by the end of the century would bring with it catastrophic consequences, including deadly heat waves<\/a>, rising seas, crop failures and mass displacement.<\/p>\n

But a scientific paper<\/a> published in April\u00a0says that doomsday pathway \u2014 known as RCP8.5 and later SSP5-8.5 \u2014 is now less probable.\u00a0Designed as a benchmark to help governments prepare for dangerous possibilities<\/a>, the worst-case scenario was not a prediction.<\/p>\n

Climate researcher Detlef Van Vuuren, lead author of the new paper, told UK-based climate science platform\u00a0Carbon Brief that it had always been a “low-probability, high-risk scenario.”<\/p>\n

It reflected the knowledge and energy trends of the late 2000s, when the world was more reliant on burning planet-heating coal, oil and gas. But those trends have now changed<\/a>.<\/p>\n

The world is not heading toward the worst-case scenario “because we’ve actually taken political measures allowing us to move away from that,”\u00a0French climate scientist Christophe Cassou told the AFP news agency.<\/p>\n

The new assessment attributes the shift to renewable energy build-out<\/a> happening faster than expected, with many governments adopting policies that have slowed projected emissions growth.<\/p>\n

Friederike Otto, a climate scientist at Imperial College London, said the worst-case scenario had “assumed humanity would continue an unchecked coal-driven fossil fuel boom, which fortunately did not happen.”<\/p>\n

While acknowledging that as “fundamentally good news,”\u00a0she urged that it “should by no means lead to complacency.”<\/p>\n

Climate skeptics seize on revised scenario\u00a0<\/p>\n

US President Donald Trump seized on the revision to claim climate scientists had been “wrong,”\u00a0fueling attacks on climate science from skeptics and politicians in both the United States<\/a>\u00a0and Europe.<\/p>\n

The far-right Alternative for Germany<\/a>\u00a0is among them. The AfD used the new narrative to argue for a rollback of the country’s climate policies during a parliamentary debate on Wednesday.<\/p>\n

Niklas H\u00f6hne, executive director and founder of Germany’s NewClimate Institute, described that play as\u00a0“a blatant diversionary tactic by climate deniers and the far right.”\u00a0As the world is in the thick of another energy crisis, he said fossil fuel defenders “will stop at nothing to fabricate a supposed scandal with outrageous arguments and divert attention from the real problems.”<\/p>\n

Cassou also said scientists “haven’t been alarmist at all.”<\/p>\n

Besides scrapping the worst-case scenario, researchers have also abandoned their most optimistic climate pathway. They warn that the world is now likely to temporarily exceed 1.5 degrees Celsius<\/a> of warming above pre-industrial levels \u2014 the threshold contained in the 2015 Paris Agreement<\/a>, as a means of avoiding the worst climate impacts.<\/p>\n

The message now is clear. As emissions have not fallen fast enough<\/a>, despite years of warnings and climate pledges, the world could still warm by around 3 degrees Celsius by 2100.<\/p>\n

That would sharply intensify climate impacts<\/a> already visible today, including increasing deadly heat waves, floods, storms and droughts. It would also imply widespread crop failures and sea-level rise<\/a>\u00a0affecting as many as 600 million people \u2014\u00a0all with widespread consequences on food security<\/a>, economies and human health.<\/p>\n

UN climate resolution faces resistance\u00a0<\/p>\n

Meanwhile, the United Nations General Assembly has approved a nonbinding resolution reinforcing countries’ obligations to combat climate change.<\/p>\n

The UN body voted overwhelmingly in favor of endorsing the advisory opinion issued last year by the International Court of Justice<\/a>. That ruling said countries could be violating international law if they fail to adequately protect people from dangerous planetary heating.\u00a0<\/p>\n

“The world’s highest court has spoken. Today, the General Assembly has answered,”\u00a0UN Secretary-General Antonio Guterres said in a statement. “This is a powerful affirmation of international law, climate justice, science, and the responsibility of states to protect people from the escalating climate crisis.”<\/p>\n

The US, which withdrew from the Paris Agreement<\/a> under Trump, as well as petrostates Russia, Iran and Saudi Arabia, opposed the measure.<\/p>\n

It is hoped that the resolution,\u00a0spearheaded by Pacific island nation Vanuatu<\/a>\u00a0\u2014 which is already facing rising seas and intensifying storms\u00a0\u2014 will strengthen the principle that governments have a legal responsibility to cut greenhouse gas emissions.\u00a0<\/p>\n

The approved text refers to the phaseout of subsidies for fossil fuel<\/a> exploration, production and exploitation, and calls for damages to be paid by those in violation.\u00a0<\/p>\n
