Why a 4°C warmer world must be avoided
Compared to the previous five-year assessment period 2011–2015, the current five-year period 2015–2019 has seen a continued increase in carbon dioxide (CO2 ) emissions and an accelerated increase in the atmospheric concentration of major greenhouse gases (GHGs), with growth rates nearly 20% high...er. The increase in the oceanic CO2 concentration has increased the ocean’s acidity.
The five-year period 2015–20191 is likely to be the warmest of any equivalent period on record globally, with a 1.1 °C global temperature increase since the pre-industrial period and a 0.2 °C increase compared to the previous five-year period.

The 2019 edition treating data for 2018 marks sustained international efforts dedicated to reporting on, analysing and understanding the year-to-year variations and long-term trends of a changing climate.
Concentrations of the major greenhouse gases, CO2 , CH4 , and N2 O, continued to increase despite the temporary reduction in emissions in 2020 related to measures taken in response to COVID-19.
2020 was one of the three warmest years on record. The past six years, including 2020, have been the si...x warmest years on record. Temperatures reached 38.0 °C at Verkhoyansk, Russian Federation on 20 June, the highest recorded temperature anywhere north of the Arctic Circle.
The trend in sea-level rise is accelerating. In addition, ocean heat storage and acidification are increasing, diminishing the ocean’s capacity to moderate climate change.

Urbanization, land use, global trade and industrialization have led to profound and negative impacts on nature, biodiversity and ecosystems across the world. The ongoing depletion of natural resources not only afects environmental conditions but also has an enormous impact on the well-being and secu...rity of societies.
This report provides an overview of the impacts of the natural environment on human health. It presents the ways nature and ecosystems can support and protect health and well-being, and describes how nature degradation and loss of biodiversity can threaten human health.

The climate crisis has many consequences – among them widespread health impacts that will lead to immense societal, ecological, and economic harm.
Over the past two decades multiple large-scale reviews on climate change and health have made clear the need for a multi-sectoral approach to target t...he drivers and impacts of climate change, biodiversity loss, and ecosystem degradation. Despite this abundance of scientific evidence underscoring urgency of action, policy implementation responses lag behind. Even at COP26, itself delayed due to an ongoing pandemic, health continues to be considered by many countries a problem independent from climate and environment.

This open access book not only describes the challenges of climate disruption, but also presents solutions. The challenges described include air pollution, climate change, extreme weather, and related health impacts that range from heat stress, vector-borne diseases, food and water insecurity and ch...ronic diseases to malnutrition and mental well-being.

We use soils to provide 98.8% of our food, but we must ensure that the pressure we place on soils to provide this food in the short-term does not inadvertently push the Earth into a less hospitable state in the long-term. Using the planeta...ry boundaries framework, we show that soils are a master variable for regulating critical Earth-system processes. Indeed, of the seven Earth-systems that have been quantified, soils play a critical and substantial role in changing the Earth-systems in at least two, either directly or indirectly, as well as smaller contributions for a further three.

This chapter addresses the biogeochemical cycles of carbon dioxide. (CO2), methane (CH4) and nitrous oxide (N2O)
This Summary for Policymakers (SPM) presents key findings of the Working Group I (WGI) contribution to the IPCC’s Sixth Assessment Report (AR6) on the physical science basis of climate change. The report builds upon the 2013 Working Group I contribution to the IPCC’s Fifth Assessment Report (AR5...) and the 2018–2019 IPCC Special Reports of the AR6 cycle and
incorporates subsequent new evidence from climate science

Global asymmetries influence policies for recovery in Latin America and the Caribbean. Nearly 30 years after the Earth Summit and the global adoption of an international development agenda, in practical terms the environmental pillar of the 2030 Agenda for Sustainable Development has not been taken ...into consideration in recovery policies in the region. This has created major problems in terms of the medium- and long-term direction of regional economies.

Ocean plastic pollution has reached crisis level: every minute, more than an entire garbage truck of plastic makes its way into the world’s oceans—roughly 11 million metric tons annually. While plastic waste presents an immediate threat to marine wildlife and ecosystems, this global challenge al...so has implications for major industries such as fishing and tourism, impacting the livelihoods of millions of people. The drivers and impacts of ocean plastic pollution also contribute to global challenges in food security, human health, and climate change.

This report presents a framework to link science, policy and practice for a comprehensive assessment of climate mitigation and adaptation investments and their impact on human health.The framework proposes to use weather and climate data to forecast health impacts over time, as well as biophysical a...nd economic models to quantify the outcomes of investments in climate change adaptation and mitigation for relevant sectoral indicators and health co-benefits. It provides guidance on the economic valuation of health co-benefits of climate action, for inclusion in sector-specific cost–benefit analysis (CBA), including the spatial allocation of such costs and benefits.
The framework developed and presented in this study is comprehensive, and provides various entry points for different audiences, including decision-makers in the public and private sectors, researchers and scientists, working in the health sector as well as in other thematic areas and related sectors affected by climate action.

The Climate Dictionary is an initiative aimed at providing an everyday guide to understanding climate change. It seeks to bridge the gap between complex scientific jargon and the general public, making climate concepts accessible and relatable to individuals from various backgrounds and levels of ex...pertise.
The concept was driven by the belief that empowering people with knowledge is crucial in fostering action and collective responsibility towards addressing climate change. By utilizing a creative combination of compelling visuals, concise explanations, and engaging storytelling, "The Climate Dictionary" effectively communicated complex climate concepts in a user-friendly and visually captivating manner. The publication features a series of climate-related term or phenomenon. The content was meticulously crafted to cater to diverse audiences, catering to both the scientifically inclined and those with limited prior knowledge of the subject.

Asia remained the world’s most disaster-hit region from weather, climate and water-related hazards in 2023. Floods and storms caused the highest number of reported casualties and economic losses, whilst the impact of heatwaves became more severe, according to a new report from the World Meteorolog...ical Organization (WMO).
The State of the Climate in Asia 2023 report highlighted the accelerating rate of key climate change indicators such as surface temperature, glacier retreat and sea level rise, which will have major repercussions for societies, economies and ecosystems in the region.
In 2023, sea-surface temperatures in the north-west Pacific Ocean were the highest on record. Even the Arctic Ocean suffered a marine heatwave.
Asia is warming faster than the global average. The warming trend has nearly doubled since the 1961–1990 period.
