Record-breaking – WMO’s new climate report confirms 2023 will be the hottest year ever — Global Issues

According to the paper, heat waves, floods, droughts, wildfires and rapidly intensifying tropical cyclones are causing misery and mayhem, upending the daily lives of millions of people and causing billions of dollars in economic losses. It is said that he gave it. W.M.O.2023 Global Climate Status Report.

Sirens are sounding across all key indicators.… Some records don’t just top the charts, some destroy them.And change is accelerating,” the United Nations said. Secretary General Antonio Guterres In the release commemorative video message.

emergency alert

The study, based on data from multiple institutions, confirmed that 2023 was the warmest year on record, with global average near-surface temperatures 1.45 degrees Celsius above pre-industrial baselines. This decade has been the warmest period on record.

“Scientific knowledge about climate change has been around for more than 50 years, but We missed an entire generation’s opportunity” said WMO Secretary-General Celeste Sauro, presenting the report to the media in Geneva. She argued that the response to climate change should be governed by “the welfare of future generations, not short-term economic gain.”

“As Director-General of the World Meteorological Organization, I am currently sounding the alarm about the state of the global climate,” she stressed.

But climate change is about more than temperature, WMO experts explain. Unprecedented ocean warmth and rising sea levels, retreating glaciers and loss of Antarctic sea ice are also part of the grim picture.

On an average day in 2023, almost a third of the ocean surface was affected by marine heatwaves, damaging vital ecosystems and food systems, according to the report.

Preliminary data shows glaciers have experienced the largest ice loss on record since 1950, with extreme melting occurring in both western North America and Europe.

Alpine ice sheets have experienced periods of extreme melting, e.g. Switzerland loses about 10 percent of its remaining production In the last two years.

Antarctic sea ice loss was the lowest on record, 1 million square kilometers less than the previous record year. Equivalent to the size of France and Germany combined.

Observed concentrations of three major greenhouse gases – carbon dioxide, methane and nitrous oxide – reached record levels in 2022 and continued to increase in 2023, according to preliminary data.

global impact

According to the report, extreme weather and climate will be either the root cause or a serious exacerbating factor causing displacement, food insecurity, biodiversity loss, health problems, etc. in 2023.

For example, the report cites figures showing that the number of people experiencing severe food insecurity around the world has more than doubled. From 149 million previously COVID-19 (new coronavirus infection) Pandemic will reach 333 million people in 78 countries in 2023 Monitored by the World Food Program (United Nations WFP).

“The climate crisis is decisive issue what humanity is facing. It is closely intertwined with the crisis of inequality, as seen in rising food insecurity, population displacement and biodiversity loss,” said Sauro.

Light of hope

The WMO report not only warns, but also provides reasons for optimism. In 2023, renewable energy capacity additions surged by almost 50% to a total of 510 gigawatts (GW), the highest record in 20 years.

The rapid increase in renewable energy generation, primarily driven by solar radiation, wind, and the water cycle, is positioning renewable energy as a leading force in combating climate change to achieve decarbonization goals.

Effective multi-hazard early warning systems are essential to reduce the impact of disasters.of Early warning for everyone The initiative aims to ensure universal protection through early warning systems by 2027.

Since the adoption of Sendai Disaster Risk Reduction Frameworkthe development and implementation of local disaster prevention strategies is increasing.

In 2021-2022, global climate finance flows nearly doubled compared to 2019-2020 levels. nearly $1.3 trillion.

However, this represents only about 1% of global GDP, highlighting a significant funding gap. Achieving the 1.5°C pathway goal will require annual climate finance investment to increase more than six times, reaching almost $9 trillion by 2030 and an additional $10 trillion by 2050. .

cost of doing nothing

The cost of inaction is staggering, the report warns. Between 2025 and 2100, Could reach $1,266 trillionrepresents the difference in loss between the business-as-usual scenario and the 1.5°C path. United Nations climate experts say this number is likely a significant underestimate and are calling for immediate action to combat climate change.

The report was released ahead of the Copenhagen Climate Ministers’ Meeting, which brings together climate change leaders and ministers from around the world for the first time. COP28 To implement the national plan, we will accelerate climate action, including submitting an ambitious agreement on funding at COP29 in Baku later this year.
