NOAA tide gauges are measuring rapid changes across the entire severity-spectrum of coastal flood risk along U.S. coastlines due to RSL rise. The most noticeable impact of RSL rise is the increasing frequency of HTF (sometimes referred to as ‘nuisance’ or ‘sunny day’ flooding), which typically causes minor and disruptive impacts. However, within many rural and urban U.S. coastal communities, the cumulative effects of more HTF upon public-works systems, roads, first floors of businesses, and residences (among others) is becoming a serious problem. Because of this, communities need projections for ‘next year’ and for the coming decades for preparedness and planning purposes to respond to the growing RSL-related HTF threat.
• Climate change litigation continues to expand across jurisdictions as a tool to
strengthen climate action, though more evidence of its impact is needed.
• Climate change cases have been brought in at least 28 countries around the
world, and of the recorded cases more than three quarters have been filed in
the United States.
• Most defendants are governments but lawsuits are increasingly targeting the
highest greenhouse-gas-emitting companies.
• Climate change-related claims are also being pursued by investors, activist
shareholders, cities and states.
• Climate change litigation in low- and middle-income countries is growing in
quantity and importance.
Climate change litigation is increasingly viewed as a tool to influence policy
outcomes and corporate behaviour. Strategic cases are designed to press national
governments to be more ambitious on climate or to enforce existing legislation,
while cases against major emitters seek compensation for loss and damage.
Routine planning and regulatory cases are increasingly including climate change
arguments, exposing courts to climate science and climate-related arguments
even where incidental to the main claim.
Environment and Climate Change
Global environmental and ecological degradation, as well as climate change, are likely to fuel competition for resources, economic distress, and social discontent through 2019 and beyond. Climate hazards such as extreme weather, higher temperatures, droughts, floods, wildfires, storms, sea level rise, soil degradation, and acidifying oceans are intensifying, threatening infrastructure, health, and water and food security. Irreversible damage to ecosystems and habitats will undermine the economic benefits they provide, worsened by air, soil, water, and marine pollution. (p 23)
Treaty on European Union, Article 191
2. Union policy on the environment shall aim at a high level of protection taking into account the diversity of situations in the various regions of the Union. It shall be based on the precautionary principle and on the principles that preventive action should be taken, that environmental damage should as a priority be rectified at source and that the polluter should pay.
The Rio Declaration on Environment and Development (1992)
In order to protect the environment, the precautionary approach shall be widely applied by States according to their capabilities. Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation.

Subnational climate change mitigation efforts will not offset the US withdrawing from the Paris Agreement.
In fulfillment of requirements of the Maryland Commission on Climate Change Act of 2015, this report provides updated projections of the amount of sea-level rise relative to Maryland coastal lands that is expected into the next century. These projections represent the consensus of an Expert Group drawn from the Mid-Atlantic region.
