International reports
IPCC Sixth Assessment Report
This report is the sixth in a series of reports assessing the available scientific information on climate change.
The 2022 Global Climate Observing System programme (GCOS) Implementation Plan
The implementation plan is a response to the findings of the 2021 GCOS Status Report, implications arising from the IPCC 6th assessment report and recent scientific studies on the climate cycles.
The Integrated Ocean Carbon Research Report
The report is a summary of ocean carbon research, and vision of coordinated ocean carbon research and observations for the next decade.
The Global Ocean Observing System (GOOS) 2030 Strategy
The report is a summary of ocean carbon research, and vision of coordinated ocean carbon research and observations for the next decade.
Global Methane Assessment Report
This report highlights the benefits and costs of mitigating methane emissions.
WMO Global GHG Watch
The World Meteorological Organization (WMO) Global Greenhouse Gas Watch (G3W) fills critical information gaps and provides an integrated, operational framework that brings under one roof all space-based and surface-based observing systems, as well as modelling and data assimilation capabilities in relation to greenhouse gas monitoring.
Tropospheric Ozone Assessment Report
TOAR's mission is to provide the research community with an up-to-date scientific assessment of tropospheric ozone's global distribution and trends from the surface to the tropopause.
Impacts of Short-lived Climate Forcers on Arctic Climate, Air Quality, and Human Health
The assessment features GML data and focuses on emissions from Arctic Council Member and Observer countries and the impacts of black carbon, methane, ozone, and sulfate aerosols on air quality, health, and climate in the Arctic.
Global Carbon Budget
The Global Carbon Budget is a key measure of progress towards the goals of the Paris Agreement. It's widely recognized as the most comprehensive report of its kind and features NOAA data and models. The budget is updated annually and published at the United Nations Climate Change Conference meetings every year.
U.S. reports
GHG National Strategy
This document highlights a set of national objectives, a conceptual framework and a phased implementation approach for a U.S. GHG Measurement, Monitoring, and Information System.
Fifth National Climate Assessment
This assessment is the U.S. government’s preeminent report on climate change impacts, risks, and responses.
Improving Characterization of Anthropogenic Methane Emissions in the United States Report
This report summarizes the current state of understanding of methane emissions sources and the measurement approaches and evaluates opportunities for methodological and inventory development improvements.
Second State of the Carbon Cycle Report
This report is an authoritative decadal assessment of carbon cycle science that examines the patterns of carbon stocks and fluxes across North America.
U.S. Ocean Acidification Action Plan
The Action Plan has three key components that include 1) an overview of U.S. federal OA actions to date (2009-2023), 2) U.S. federal priorities for OA research, knowledge applications, and policy integration moving forward, and 3) best practices and recommendations for other national governments developing OA Action Plans.
Strategic Plan for Federal Research and Monitoring of Ocean Acidification
This plan will guide federal research and monitoring investments that will improve our understanding of ocean acidification, its potential impacts on marine species and ecosystems, and adaptation and mitigation strategies.
