Global Warming Threat Still Looms This Century, UN Warns
(MENAFN) Despite fresh climate pledges, the world remains on a trajectory toward dangerous levels of warming this century, the UN Environment Programme (UNEP) warned Tuesday.
In its 16th Emissions Gap Report, UNEP said that even if all current national climate plans are fully implemented, global temperatures are expected to rise between 2.3C (4.14F) and 2.5C (4.5F) by 2100. Under existing policies, the increase could reach around 2.8C (5.04F).
The report noted this represents only a marginal improvement from last year’s projection of 2.6C (4.7F) to 2.8C (5F), adding that new nationally determined contributions “have barely moved the needle.”
Countries remain “far from meeting the Paris Agreement goal to limit warming to well below 2C (3.6F), while pursuing efforts to stay below 1.5C (2.7F),” the report said.
To meet those targets, global emissions would need to fall by 35% to 55% from 2019 levels by 2035. The report highlighted that given the scale of cuts required and “a challenging political climate,” exceeding 1.5C (2.7F) is “very likely within the next decade.”
“This overshoot must be limited through faster and bigger reductions in greenhouse gas emissions” to reduce risks and damages, the report added.
“Every fraction of a degree avoided means lower losses for people and ecosystems, lower costs and less reliance on uncertain carbon dioxide removal techniques,” it emphasized.
On a slightly positive note, UNEP pointed out that global temperature projections have decreased from 3C–3.5C (5.4F–6.3F) since the adoption of the Paris Agreement a decade ago. “The required low-carbon technologies to deliver big emission cuts are available. Wind and solar energy development is booming, lowering deployment costs,” the agency noted.
UNEP said the world still has the potential to “accelerate climate action, should they choose to do so,” but warned that achieving faster cuts “would require navigating a challenging geopolitical environment, delivering a massive increase in support to developing countries and redesigning the international financial architecture.”
UN Secretary-General Antonio Guterres described the report as “clear” and “uncompromising” in a post on the US social media company X. He added, “The upcoming COP30 Climate Conference must be the turning point where the world delivers a bold and credible response plan.”
The UN Climate Change Conference COP30 is scheduled to begin next Monday in Brazil.
