Scientific evidence that can be used in litigation

The reports of the Intergovernmental Panel on Climate Change (IPCC) have been very helpful in solving court cases on climate change, as this scientific information shows the scope, effects, and causes of climate change. It is important to cite and encourage the courts to view the IPCC reports as a respected authority on climate science, so that arguments made in defense of the environment cannot be dismissed.

 * Changes upper ocean has warmed
 * Salinity and freshwater content
 * Ocean surface fluxes
 * Water-mass properties
 * Ocean circulation
 * Sea level change, including extremes
 * Ocean biogeochemical changes, including anthropogenic ocean acidification

Sea Level Change
This document considers changes in global mean sea level, regional sea level, sea level extremes, and waves. It also contains:
 * Projections of Components and Models of Sea Level Change
 * Past Sea Level Change
 * Contributions to Global Mean Sea Level Rise during the Instrumental Period
 * Projected Contributions to Global Mean Sea Level

Detection and Attribution of Climate Change: from Global to Regional
This study addresses atmospheric temperatures. More than half of the observed increase in global mean surface temperature from 1951 to 2010 is very likely due to the observed anthropogenic increase in greenhouse gas  concentrations. The consistency of observed and modeled changes across the climate system, including warming of the atmosphere and ocean, sea level rise, ocean acidification and changes in the water cycle, the cryosphere, and climate extremes points to a large-scale warming, resulting primarily from anthropogenic increases. You can learn more specifically about:
 * Evaluation of detection and attribution methodologies
 * Atmosphere and surface
 * Changes in ocean properties
 * Cryosphere
 * Extremes
 * Multi-century to millennia perspective
 * Implications for climate system properties and projections

Climate Phenomena and their Relevance for Future Regional Climate Change
This document assesses the scientific literature on projected changes in major climate phenomena and, more specifically, their relevance for future change in regional climates, contingent on global mean temperatures continue to rise. It also says that Regional climates are the complex result of processes that vary strongly with location and so respond differently to changes in global scale influences. More specifically it includes:
 * Monsoon systems
 * Tropical phenomena
 * El Niño- southern oscillation
 * Annular and dipolar modes
 * Large-scale storm systems
 * Additional phenomena of relevance
 * Future regional climate change

Carbon and Other Biogeochemical Cycle
This document addresses the biogeochemical cycles of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). The three greenhouse gases (GHGs) have increased in the atmosphere since pre-industrial times, and this increase is the main driving cause of climate change. The increase of CO2, CH4, and N2O is caused by anthropogenic emissions from the use of fossil fuel as a source of energy and from land use and land use changes, in particular agriculture. The observed change in the atmospheric concentration of CO2, CH4, and N2O results from the dynamic balance between anthropogenic emissions, and the perturbation of natural processes that leads to a partial removal of these gases from the atmosphere. You can learn more specifically about:
 * Variations in carbon and other biogeochemical cycles before the fossil fuel era
 * Evolution of biogeochemical cycles since the Industrial Revolution
 * Projections of future carbon and other biogeochemical cycles
 * Potential effects of carbon dioxide removal methods
 * Solar radiation management on the carbon cycle

Evaluation of Climate Models
This document includes models for the representation of biogeochemical cycles important to climate change. These models allow for policy-relevant calculations such as the carbon dioxide (CO2) emissions compatible with a specified climate stabilization target. This evaluation is based on recent internationally coordinated model experiments, including simulations of historic and paleo climate, specialized experiments designed to provide insight into key climate processes and feedbacks and regional climate downscaling. You can learn more specifically about:
 * Climate models and their characteristics
 * Techniques for assessing model performance
 * Experimental strategies in support of climate model evaluation
 * Simulation of recent and longer-term records in global models
 * Simulation of variability and extremes
 * Downscaling and simulation of regional-scale climate
 * Climate sensitivity and climate feedback
 * Relating model performance to credibility of model applications
