Climate Change

Customized intelligence for your unique weather and climate needs

in assessing the impacts of climate variability and change

The impacts of climate change are occurring around the world in different ways and at different rates. CFAN works with clients to evaluate and assess risks from climate change impacts for their organization or region.


CFAN’s climate change assessments drawing on years of experience working on projects for corporations and in vulnerable regions around the world. CFAN and its affiliates have expertise in the following sectors that are impacted by climate variability and change: transportation, energy, agriculture, forestry, water resource management, infrastructure and building construction, and financial services.  In addition to North America, CFAN team members have expertise and experience in the following regions: Central America, South America, and Asia.

CFAN’s climate services include:

  • Corporate climate risk management

  • Climate scenarios and impact assessments

  • Expert reports and testimony

  • Support for climate-related litigation

Corporate climate-related risk management


There is a growing need for corporations to not only understand and increase resilience to climate-related risks, but also to provide climate-related disclosures for investors and capital markets. Guidelines have recently been provided by the Task Force on Climate-Related Disclosures and proposed rules by the U.S. Securities and Exchange Commission under The Enhancement and Standardization of Climate-Related Disclosure for Investors, although there is substantial room for interpreting these guidelines and directives in many different ways.


Corporations face a broad array of climate-related risks. Physical risks include harm to businesses and assets arising from extreme weather events such as wildfires, hurricanes, tornadoes, floods, and heatwaves. Chronic and emerging risks include more gradual impacts from drought and sea level rise. Systemic risks arise from myriad complex impacts throughout the value chain, both upstream and downstream.  Risks are also associated with the transition to lower carbon products and services that are motivated by regulatory, technological and market changes. In addition to addressing these risks, businesses can face significant challenges in making accurate public disclosures.


Climate Forecast Applications Network (CFAN) has the expertise and experience that is advising businesses in multiple industries in meeting these challenges. CFAN can help integrate climate-related risk into your business and policy decisions, and provide climate-related risk information to investors:

  • Understanding and conveying relevant aspects of climate science

  • Climate-related scenario analysis

  • Corporate climate-related risk assessments

  • Corporate climate resilience strategy

  • Decision making under uncertain conditions and management of systemic risks


CFAN’s President Judith Curry has written a book entitled Climate Uncertainty and Risk [link], forthcoming from Anthem Press, which provides the foundation for understanding climate risk, developing regional, decadal-scale scenarios for weather and climate extremes, assessing and managing systemic climate risk, and principles for decision making under deep uncertainty. 

Climate scenarios & impact assessment





Climate variability and change can have substantial impacts on strategic planning, infrastructure, capacity building, and needs for technology development.  CFAN has experience in producing climate impact assessments for individual institutions, industry sectors, and regional integrated impact assessments.  CFAN can undertake an independent climate risk assessment or support an established risk assessment team.

CFAN's climate impact assessments include historical analyses and decadal scale scenarios of future climate change that can be used to drive sectoral or regional risk assessment models.  Our scenarios of future climate change integrate projections of human-caused climate change with natural modes of climate variability.  Extreme event scenarios consist of frequency distribution of regional extreme events over the target time interval, as well as worst-case scenarios of individual events.  Providing a range of possible scenarios enables decisions that are robust across a range of possible outcomes, and allows for focus on scenarios in the vicinity of your vulnerability thresholds.

Expert Testimony

CFAN’s President has extensive experience in preparing and presenting expert testimony, both for Congressional Hearings and for litigation related to climate change and its impacts.

CFAN President Judith Curry’s recent Congressional testimony:

  • House 6/12/19 :Contending with Natural Disasters in the Wake of Climate Change [link]

  • House 2/6/19  : Climate Change: The Impacts and the Need to Act [link]

  • House 5/16/18: Using Technology to Address Climate Change [pdf]

  • House 3/29/17:  Climate Science: Assumptions, Policy Implications and the Scientific Method  [link]

  • Senate 12/08/15:  Data or Dogma?  Promoting Open Inquiry in the Debate Over the Magnitude  of Human Impact on Climate change [pdf] 

  • House 4/15/15:  The President’s U.N. Climate Pledge [pdf]

  • Senate 1/16/14:  Review of the President’s Climate Action Plan [pdf]

  • House 4/25/13:  Policy Relevant Climate Issues in Context [pdf]

Support for litigation

Climate science is becoming increasingly important in litigation. According to the UNEP Global Review on the Status of Climate Change Litigation [link], as of March 2017, climate change cases had been filed in 24 countries, with 654 cases filed in the U.S.  
With the growing policy emphasis upon adaptation to climate change and attribution of the causes of extreme weather and climate events, the potential for disputes will multiply.


CFAN’s owners President Judith Curry and Peter Webster brings a wealth of experience and expertise for supporting litigation related to climate change. The following services can be provided for litigation:

  • Provide factual information and background relevant to the decision/policy and the litigation

  • Consult with attorneys and examine documents

  • Assist attorneys in deposition and cross-examination of experts

  • Prepare expert and rebuttal reports

  • Assist attorneys in preparation pre- and post-trial submissions

  • Testify at trial
