Our weather, climate, and water cycle know no boundaries. International cooperation is essential to contending with our changing climate.  World Meteorological Day (23 March) is a reminder of it. This year, the observance day also marks WMO’s 150th anniversary. Throughout this time, meteorological services have worked around the clock to collect and standardize data that underpin the weather forecasts we now take for granted. The history of WMO is a remarkable story of scientific vision, technological development, and a unique cooperation system to serve society. Share its history!

The Intergovernmental Panel on Climate Change (IPCC) is holding its 58th session (13-17 March) in Switzerland. This is the last step towards the launch of its latest flagship publication, the Synthesis Report, set to be released on 20 March. This document will provide policymakers with a high-level, up-to-date understanding of climate change, its impacts, future risks, and options for addressing it. During the session the Panel, consisting of 195 IPCC member governments, will conduct the final review and approval of this report, which is expected to confirm that inaction is no longer an option.

People everywhere are taking steps to be part of the solution to the climate crisis. More than 10 million actions have been logged through the UN’s ActNow campaign. ActNow is the United Nations campaign for individual action on climate change and sustainability. Every one of us can help limit global warming and take care of our planet. Learn more about the campaign and log in your actions through the mobile app.

The planet is experiencing a dangerous decline of nature due to human activity. One million plant and animal species are threatened with extinction. The recent adoption of the Kunming-Montreal Global Biodiversity Framework, a global blueprint to save the planet’s dwindling biodiversity, will try to reverse this nature loss through a package of ambitious targets. But why is biodiversity so crucial to combat climate change? Discover the reasons that make biodiversity our strongest natural defense against climate change.

Methane: you’ve probably heard of it, but what is it and why is it important to reduce it? Methane is a greenhouse gas mainly emitted from dumpsites, oil and gas wells, coal mines, wetlands and cow burps.

Faced with a growing energy crisis, record greenhouse gas concentrations, and increasing extreme weather events, COP27 in Sharm el-Sheikh (6 to 18 November) see

On September 7, the UN marked the third International Day of Clean Air for Blue Skies. However, the skies are far from clear of air pollution. Only a month ago, the World Health Organization (WHO) warned that practically all the air we breathe is polluted, and that it’s killing around seven million people every year.

Conor Lennon from UN News spoke to Martina Otto and Nathan Borgford-Parnell from the Climate and Clean Air Coalition, which is hosted by the UN Environment Programme (UNEP). They discussed the evolving science surrounding the issue, the extent to which air pollution is improving – if at all – and why international collaboration is essential, if the number of annual deaths is to be addressed.

Together with the Government of Japan, the UN Department of Political and Peacebuilding Affairs (UN DPPA) developed a Virtual Reality (VR) experience on climate change in the Asia Pacific region. This documentary captures impressions of participants and comments of the organizers during the launch event for the VR experience in New York City. In April 2022, DPPA released the VR experience “Sea of Islands” that brings viewers virtually to the Pacific islands to see the impact of the climate crisis. It encourages viewers to grasp the urgency, scale and pressing nature of climate change.

Nature-based solutions like habitat restoration, reforestation, coastal protection and invasive species removal create jobs at over 10 times the rate of fossil fuels.

Thirty years ago, the Earth Summit, which took place in the Brazilian city of Rio de Janeiro, paved the way for the establishment of three major conventions on the environment - specifically on biodiversity, climate change and desertification. As countries meet on all three conventions in 2022, SDG Advocate and indigenous rights activist Hindou Ibrahim talks about the indispensable role that indigenous communities around the world play in protecting life on our planet - its biodiversity, land and climate. 

Rich and healthy soils are the basis of all life on Earth. Yet up to 40 percent of the planet’s land is degraded, affecting half the world’s population. Especially at risk are people living in drylands – covering 45 percent of the Earth’s surface – which are prone to desertification and the devastating impacts of climate-related shocks such as disease, drought, flooding and wildfire. Around 12 million hectares of land are lost each year to degradation. UNDP and its partners are working towards a land degradation-neutral world, to support ecosystem functions and improve food security.

A mother of three children, Laiku Lama worked as a farmer in the mountainous district of Humla, one of the most isolated and underdeveloped regions in Nepal. In 2018, she left her family to board a plane for the first time in her life. After six months studying in India, she literally enlightened her village upon her return: as a newly certified solar technician, she installed solar home lighting in 220 houses, benefitting over 2,100 people. Laiku was one of three Lama women who became so-called Solar Mamas, thanks to a South-South cooperation initiative.

Demonstrating the wide-ranging consequences of the climate crisis, the UN Human Rights Council has appointed the first-ever Special Rapporteur on the Promotion and Protection of Human Rights in the context of Climate Change. Ian Fry, who is of Australian and Tuvalu heritage, teaches environmental policy at the Australian National University in Canberra. As UN Special Rapporteur, he will be tasked with studying how climate change affects the full enjoyment of human rights, and recommend ways to prevent these effects.

In an interview with the UN’s Julia Dean, Mr. Fry explained why the Human Rights Council created his new role.
