Washington state has a varied and active economy of approximately $268.5 billion. Washington's gross state product is the sum of twenty-one economic sectors ranging from mining ($400 million in 2004) to real estate, rental, and leasing ($38.8 billion) in 2004. The extent of vulnerability in dealing with climate-related issues is hard to assess for each sector individually. National and international trade and inter-sector links stretch out the vulnerability to climate change effects.[citation needed]
