UNEP Report Launch: Navigating 1.5°C Warming – Press Conference | United Nations

Source: United Nations (video statements)

UN Environment Programme (UNEP) Executive Director Inger Andersen spoke to reporters today (2 Sep) via video link from Nairobi. She introduced the Programme’s new report, Limiting Overshoot, which identifies an ‘overshoot, peak, and decline’ pathway as the best remaining option to minimize the magnitude and duration of this overshoot and try to return to below 1.5°C as soon as possible.

Andersen said, “this report tells us that global temperature rise is set to cross the 1.5°C above pre-industrial level, and thereby crossing what the world agreed during the Paris Agreement talks in 2015, and this will likely be taking place within the next few years.”

“This is the legacy of our own inaction,” she emphasized, adding “across the globe, extreme heat waves are already proving that climate impacts will strike faster, hit harder and last longer, costing more lives and causing deeper disruptions.”

The Executive Director warned, “above 1.5°C, we can expect an intensification of extreme weather, of glacier melt, of ecosystem loss, and of sea level rise and human health and food and water security. Cities and infrastructure will come under increasing strain.”

Andersen underscored the options, she said “how to – by getting on a so-called overshoot peak and decline pathway, how to make that journey. And that means keeping the peak as low as possible and keeping the peak as short as possible, and then working very hard to bring the temperature back down as quickly as possible. Structure will come under increasing strain.”

The UNEP chief reiterated, “the quickest and most effective way that we can do this is by accelerating transition away from fossil fuels, delivering deep cuts to CO2, methane and other greenhouse gas gases obviously.”

She added, “Addressing key sectors, obviously energy, but also cooling and energy efficiency, demand and supply side reform will remain important. And this will determine how long the overshoot lasts and whether we are able to bring that temperature back down.”

Andersen highlighted, “we need stronger political will and stronger multilateralism. We need more agile and inclusive governance. We need to consider equity and justice, because that has to be at the core of all actions. And we will, of course, need much more finance. Countries with greater historical responsibility for climate change should do the most work.”

“The future will bring many unknowns, but we do know that decisions taken now will determine if we have a chance of returning to 1.5 or below,” Executive Director said, reiterating, “every fraction of a degree avoided, every year by which the overshoot is shortened, and every adaptation action taken will save lives, will protect ecosystems, and reduce economic losses.”

CLIMATE REPORT/OVERSHOOT

In a video message on the launch of the latest UN Environment Programme (UNEP) report, called “Limiting Overshoot: Navigating exceedance of 1.5°C and pathways towards return”, the Secretary-General noted that humanity is speeding past the limit to avoid climate catastrophe. He pointed out that we are set to breach the 1.5 degree limit within the next few years, and this summer’s scorching heat, raging wildfires and deadly floods are a warning of what lies ahead.

The Secretary-General warned that every fraction of a degree will cost lives, will destroy livelihoods, will deepen

inequality and push ecosystems closer to irreversible damage. He stressed that we must make the overshoot as small and short as possible, limiting how high temperatures rise and how long they remain above 1.5, and that the fight for 1.5 degrees is the fight for humanity.

IRAN

The Secretary-General is gravely concerned by the renewed exchanges of fire overnight between the United States and the Islamic Republic of Iran. The Secretary-General is deeply alarmed by reports of civilian casualties, including in a strike that reportedly hit a wedding ceremony in Iran. The Secretary-General condemns all attacks against civilians. He recalls that all parties must respect their obligations under international humanitarian law, including the principles of distinction, proportionality, and precaution.

As we have seen, few countries in the region are immune from this escalation, with airspace and critical shipping routes continuing to be heavily impacted.

The Secretary-General reiterates his call for an immediate cessation of military action and urges all concerned to exercise restraint and refrain from actions and rhetoric that could further escalate already high tensions.

Further escalation, as you can imagine, would have devastating consequences for civilians and for the wider region and beyond.

The Middle East escalation has had a devastating impact on civilians and added further pressure on humanitarian needs and operations across the region and beyond. In a region already facing many humanitarian crises, this risks further deterioration at a time when humanitarian operations are already overstretched and underfunded, as we tell you repeatedly. Despite the challenges, we and our humanitarian partners continue to respond with life-saving assistance wherever we can, and whenever we can.

The Secretary-General urges the United States and the Islamic Republic of Iran to return urgently to diplomacy. A comprehensive and durable settlement can be achieved only through dialogue and negotiations.
