Climate Change News: UN Report Calls for Action to Prevent 3.1C Warming by 2100

According to recent climate change news report, the United Nations has declared the global climate situation to be at crunch time. A report from the United Nations Environment Programme warns that current climate policies are inadequate to curb warming to the 1.5C limit set by the Paris Agreement. Instead, without intervention, the world is on track for a 3.1C increase by 2100.

The UNEP report forecasts a 3.1C rise by 2100 if global commitments remain unchanged. This level of warming surpasses the Paris Agreement’s ideal target of 1.5C.

Even if all current pledges are fulfilled, the world would still experience a warming range of 2.6C to 2.8C, leading to climate-related disasters.

The Paris Agreement aimed to keep global warming well below 2C, with a goal of limiting it to 1.5°C. Achieving this target requires reductions in emissions, which UNEP’s report indicates are not on track.

With less than 1.5°C of warming, the planet has already faced heatwaves, storms and floods. Exceeding this threshold could amplify these events increasing risks to communities, ecosystems and economies.

According to recent climate change news report, G20 countries account for around 80% of all greenhouse gas emissions. China, responsible for 30% of global emissions and the United States, contributing 11%, are urged to lead the way in emission reductions.

The report shows that some major emitters including China and India, have yet to peak their emissions.

NDCs must now reflect the 1.5C target with measurable action plans. By February 2025, ahead of COP30 in Brazil, countries must submit revised NDCs to show commitments to climate action.

The NDCs must include targets for reducing emissions across all sectors, from transportation and construction to energy production.

Under the Paris Agreement, countries must submit updated NDCs every five years. UNEP urges nations to submit more targets in February 2025 and at COP29 in Baku, Azerbaijan.

To maintain the 1.5C target, countries must collectively reduce emissions by 42% by 2030 and 57% by 2035. Achieving these reductions would require cutting emissions equivalent to those of the entire European Union annually for over a decade.

UNEP highlights solar and wind energy as essential technologies that could account for 27% of required emissions reductions by 2030 and 38% by 2035.

Increasing investment and deployment in these sectors are necessary steps. Protecting and restoring forests could deliver another 20% of necessary emissions cuts.

UNEP calls for a coordinated whole-of-government approach, ensuring climate action across energy, transport, industry and building sectors.

Improving energy efficiency, transitioning to clean fuels and electrifying key sectors are fundamental steps in this strategy.

With G20 countries accounting for nearly 80% of global emissions. UNEP stresses that these major economies must lead the way by setting higher targets and implementing aggressive carbon reduction strategies.

According to recent climate change news report, UNEP Executive Director Inger Andersen addressed the need to phase out fossil fuels swiftly and fairly, stating, “Political courage is needed to end our fossil fuel addiction.”

UNEP points out that technologies like solar, wind and energy efficiency upgrades are proven solutions available today.

UNEP estimates the annual cost of necessary climate action to be between $1-2 trillion, representing about 1% of the global economy. This includes funding for renewable energy infrastructure, technology transfer and reforestation.

The report calls on wealthier countries to provide financial assistance to developing nations, which are disproportionately affected by climate impacts yet contribute minimally to global emissions.

The upcoming COP29 summit in Baku provides a platform for nations to set stronger NDCs and commit to rapid emission cuts.

UNEP and the UN Secretary-General, António Guterres urge countries to turn ambitious words into actionable policies. Delay in action could mean more measures will be needed in the future.

Each year that passes without cuts makes it more challenging and expensive to stay within the 1.5C limit.

According to recent climate change news report, the report estimates that between $900 billion and $2.1 trillion annually will be necessary until 2050 to support the transition to renewable energy and energy-efficient practices.

COP29 is a chance for major economies particularly the G20 to showcase ambitious climate goals. COP30 in Brazil in 2025 is anticipated as a milestone, where countries are expected to present strengthened NDCs in line with the 1.5C target.

UNEP stresses that actions taken over the next decade will determine the course of global climate health, with rapid, far-reaching changes needed immediately.

Even if all current pledges are met, global temperatures would still exceed the 1.5C target, requiring more steps.

UNEP’s annual reports have repeatedly warned about the closing window for climate action. The latest report reaffirms that time is running out to limit warming and meet the goals of the Paris Agreement.

Inger Andersen states, “This is it. Now is the time for global mobilization on an unprecedented scale.”
