From March 2021 through May 2021 we are seeking volunteers! Looking for contributors to provide design consulting, assist with finding/classifying papers, or just give feedback. Email to express your interest.

Only observational studies: on the effects of climate change, and how we know CO2 is causing it.

No model simulations. No future predictions. All peer-reviewed.

Warming -- Automatically updated charts of global warming from multiple data sets.
Anthropogenic -- Observational evidence attributing this warming to greenhouse gases. (67 papers.)
Effects -- Observed effects of warming on humanity to date, by type and by region. (281 papers.)

ClimateObserved is not a blog or opinion site. It is a custom-built web application for a carefully categorized database of peer-reviewed papers. It is the only database available which consists exclusively of papers based on observations over time, rather than predictions, theory, or controlled experiments.

Candidate papers are found from a range of sources, and are always read and hand-selected to ensure they are based on real-world observations. It is updated monthly (last update 2021-03-26) as new research is published. In this sense, it is meticulously documenting global warming as its effects continue to unfold.

The intention of this site is to be an easily searchable resource for papers that indicate an anthropogenic cause of climate change since the mid-20th century, and papers which have observed any negative impact(s) on humanity -- no monarch butterflies, treefrogs, or glacier retreat in faraway places. Only negative impacts on humans, such as drought, flooding, disease spread, extreme weather, etc. are included. Human impact papers are categorized by type, geographic region, and means of attribution to climate change, and all papers include a selected "key quote" for easy citing.

It is a completely free-to-use tool for finding reputable and relevant citations from the scientific literature, to aid users in their efforts to understand and communicate the realities of climate change.

To ensure long-term reliability and prevent broken links, all papers are stored as their permanent DOI handle rather than a journal-specific URL.
