Increasing temperatures and sea levels, changing precipitation patterns and more extreme weather are threatening human health and safety, food and water security and socio-economic development in Africa, according to the State of the Climate in Africa Report devoted exclusively to the continent. The report provides a snapshot of current and future climate trends and associated impacts on the economy and sensitive sectors like agriculture. It highlights lessons for climate action in Africa and identifies pathways for addressing critical gaps and challenges.
Between 1970 and 2019, 79% of disasters worldwide involved weather, water, and climate-related hazards. These disasters accounted for 56% of deaths and 75% of economic losses from disasters associated with natural hazards reported during that period. As climate change continues to threaten human lives, ecosystems and economies, risk information and early warning systems (EWS) are increasingly seen as key for reducing these impacts. This latest WMO report highlights progress made in EWS capacity – and identifies where and how governments can invest in effective EWS to strengthen countries’ resilience to multiple weather, water and climate-related hazards.
Climate change has not stopped for COVID19. United in Science 2020, a new multi-agency report from leading science organizations, highlights the increasing and irreversible impacts of climate change, which affects glaciers, oceans, nature, economies and human living conditions and is often felt through water-related hazards like drought or flooding. It also documents how COVID-19 has impeded our ability to monitor these changes through the global observing system.
The tell-tale physical signs of climate change, such as increasing land and ocean heat, accelerating sea level rise and melting ice, contributed to making 2019 the second warmest year on record according to a new report compiled by a network led by the World Meteorological Organization. The report documents the increasing impacts of weather and climate events on socio-economic development, human health, migration and displacement, food security and land and marine ecosystems.
The physical signs and socio-economic impacts of climate change are accelerating as record greenhouse gas concentrations drive global temperatures towards increasingly dangerous levels, according to a new report from the World Meteorological Organization.
The WMO Statement on the State of the Global Climate in 2018 , its 25th anniversary edition, highlights record sea level rise, as well as exceptionally high land and ocean temperatures over the past four years. This warming trend has lasted since the start of this century and is expected to continue.
Limiting global warming to 1.5ºC would require rapid, far-reaching and unprecedented changes in all aspects of society, the Intergovernmental Panel on Climate Change (IPCC) said in a new assessment. With clear benefits to people and natural ecosystems, limiting global warming to 1.5ºC compared to 2ºC could go hand in hand with ensuring a more sustainable and equitable society.
The WMO Greenhouse Gas Bulletin reports on atmospheric concentrations of greenhouse gases in the earth’s atmosphere. The report found that levels of heat-trapping greenhouse gases in the atmosphere have reached another new record high, according to the World Meteorological Organization. There is no sign of a reversal in this trend, which is driving long-term climate change, sea level rise, ocean acidification and more extreme weather.
The Synthesis Report (SYR) of the IPCC Fifth Assessment Report (AR5) provides an overview of the state of knowledge concerning the science of climate change. It shows that human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history. Recent climate changes have had widespread impacts on human and natural systems.
As the world strives to cut greenhouse gas emissions and limit climate change, it is crucial to track progress towards globally agreed climate goals. For a decade, UNEP’s Emissions Gap Report has compared where greenhouse gas emissions are heading against where they need to be, and highlighted the best ways to close the gap.
The flagship report from UN Environment is the definitive assessment of the 'emissions gap' – the gap between anticipated emission levels in 2030, compared to levels consistent with a 2°C / 1.5°C target. It found that global emissions are on the rise as national commitments to combat climate change come up short. But surging momentum from the private sector and untapped potential from innovation and green-financing offer pathways to bridge the emissions gap.
CBD | The Global Biodiversity Outlook 5 Report (2020)
Despite encouraging progress in several areas, the natural world is suffering badly and getting worse. The Global Biodiversity Outlook 5 (GBO-5) calls for a shift away from “business as usual” across a range of human activities. The report outlines eight transitions that recognize the value of biodiversity, the need to restore the ecosystems on which all human activity de-pends, and the urgency of reducing the negative impacts of such activity. It also shows that governments will need to scale up national ambitions in support of the new Global Biodiversity Framework and ensure that all necessary resources are mobilized, and the enabling environment strengthened.
IPCC | Special Report on the Ocean and Cryosphere in a Changing Climate (2019)
The IPCC Special Report highlights the urgency of prioritizing timely, ambitious and coordinated action to address unprecedented and enduring changes in the ocean and cryosphere. Without a radical change in human behavior, hundreds of millions of people could suffer from rising sea levels, frequent natural disasters and food shortages, it warns.
The Special Report provides new evidence for the benefits of limiting global warming to the lowest possible level – in line with the goals of the 2015 Paris Agreement. It also finds that strongly reducing greenhouse gas emissions, protecting and restoring ecosystems, and carefully managing the use of natural resources would make it possible to preserve the ocean and cryosphere.
The UN Development Programme (UNDP) and UN Climate Change (UNFCCC) have been working together since 2014 to support countries in developing their national climate plans --Nationally Determined Contributions for the Paris Agreement or NDCs. This report is the most detailed review yet of momentum since the Paris Agreement and is designed to both inspire and inform the UN Climate Action Summit in New York on 23 September.
UN Environment’s sixth Global Environment Outlook (2019) calls on decision makers to take immediate action to address pressing environmental issues to achieve the Sustainable Development Goals as well as other Internationally Agreed Environment Goals, such as the Paris Agreement.
By bringing together a community of hundreds of scientists, peer reviewers and collaborating institutions and partners, the GEO reports build on sound scientific knowledge to provide governments, local authorities, businesses and individual citizens with the information needed to guide societies to a truly sustainable world by 2050.
Land is already under growing human pressure and climate change is adding to these pressures. At the same time, keeping global warming to well below 2ºC can be achieved only by reducing greenhouse gas emissions from all sectors including land and food, the Intergovernmental Panel on Climate Change (IPCC) states in its latest report.
The report provides key scientific input into forthcoming climate and environment negotiations, such as the Conference of the Parties of the UN Convention to Combat Desertification (COP14) in New Delhi, India in September and the UN Framework Convention on Climate Change Conference (COP25) in Santiago, Chile, in December.
September’s Climate Action Summit delivered important new actions, a surge in climate momentum, and a clear destination: 45% emissions cuts by 2030 on the way to a carbon neutral world by 2050. The Secretary-General’s report on the outcomes of the Summit highlights the way forward in 2020, and outlines ten priority areas of action.
The report “Climate Action and Support Trends” was prepared as UN Climate Change input to the UN Climate Action Summit, and it puts a spotlight on the progress made over the past 25 years since the inception of the UN Framework Convention on Climate Change (UNFCCC). This can help in scaling up further action, as governments prepare to submit the next round of national climate action plans, known as Nationally Determined Contributions (NDCs), by 2020.
The next 2-3 years are a critical window when many of the policy and investment decisions that shape the next 10-15 years will be taken. The New Climate Economy report found that leaders are already seizing the exciting economic and market opportunities of the new growth approach, while the laggards are not only missing out on these opportunities but are also putting us all at greater risk. More than US$26 trillion and a more sustainable planet are on offer, if everyone gets on board.
