This will require large-scale, rapid and systemic transformations. To get on track to meet the Paris Agreement goals of limiting warming to well below 2 ☌ and preferably 1.5 ☌, global greenhouse gas emissions must be reduced by 30% and 45%, respectively, by 2030, with carbon dioxide (CO 2) emissions getting close to net zero by 2050. Fossil fuel CO2 emissions increased 1% globally in 2022 compared to 2021 and preliminary estimates from January-June 2023 show a further 0.3% rise. So far, there has been very limited progress in reducing the emissions gap for 2030 – the gap between the emissions reductions promised by countries and the emissions reductions needed to achieve the temperature goal of the Paris Agreement. The chance of the annual mean global near-surface temperature temporarily exceeding 1.5 ☌ above pre-industrial levels for at least one of the next five years is 66% and is increasing with time. Rising global temperatures have been accompanied by more extreme weather. Over 90% of these reported deaths and 60% of economic losses occurred in developing economies, undermining sustainable development. The need for science and solutions is more urgent than ever.īetween 19, there were nearly 12 000 reported disasters from weather, climate and water extremes, causing over 2 million deaths and US$ 4.3 trillion in economic losses. And early-warning systems help to reduce poverty by giving people the chance to prepare and limit the impact. Integrating epidemiology and climate information helps understand and anticipate those diseases sensitive to climate. The report shows, for example, how weather predictions help boost food production and move closer to zero hunger. And achieving Early Warnings for All by 2027 will not only save lives and livelihoods but also help safeguard sustainable development,” he comments. “Groundbreaking scientific and technological advances, such as high-resolution climate modelling, artificial intelligence and nowcasting, can catalyze transformation to achieve the SDGs. “At this pivotal moment in history, the halfway mark to achieving the SDGs, the science community stands united in the effort to achieve prosperity for people and the planet,” says WMO Secretary-General Prof. But it is less recognized how these sciences can supercharge progress on the SDGs across the board,” Mr Guterres writes in the foreword. It is widely understood that weather, climate, and water-related sciences provide the underpinnings for climate action. Meanwhile, halfway to the 2030 deadline for the Sustainable Development Goals (SDGs), the world is woefully off-track,” says UN Secretary-General António Guterres. While we know this is just the beginning, the global response is falling far short.
Record temperatures are scorching the land and heating the sea, as extreme weather causes havoc around the globe. “2023 has shown all too clearly that climate change is here. It is issued ahead of the SDG Summit and Climate Ambition Summit at the United Nations General Assembly. The annual report combines input and expertise from 18 organizations. It illustrates how weather, climate and water-related sciences can advance aims such as food and water security, clean energy, better health, sustainable oceans and resilient cities. Only 15% of the Sustainable Development Goals (SDGs) on track, says the United in Science report, which makes a systematic examination of the impact of climate change and extreme weather on the goals. This undermines global efforts to tackle hunger, poverty and ill-health, improve access to clean water and energy and many other aspects of sustainable development, according to a new multi-agency report coordinated by the World Meteorological Organization (WMO).
