• June 2018 ranks third warmest on record for U.S.

    Hot temperatures continued to bake the United States last month, making it the third warmest June on record. We are halfway through 2018 and the United States has already experienced $6-billion-dollar weather disasters.

  • Sea level rise and coastal development: Science speaks directly to business

    If you are an investor or a developer with an interest in coastal properties, you are being bombarded with evidence of climate change in the form of sea level rise and its consequences. In the academic community, many interested in the business of coastal development have begun to take into account information from climate scientists and have expressed frustration that government regulators are not doing so.

  • 3 reasons why the U.S. is vulnerable to big disasters

    During the 2017 disaster season, three severe hurricanes devastated large parts of the U.S. The quick succession of major disasters made it obvious that such large-scale emergencies can be a strain, even in one of the world’s richest countries. Why do some countries better withstand and respond to disasters? The factors are many and diverse, but three major ones stand out because they are within the grasp of the federal and local governments: where and how cities grow; how easily households can access critical services during disaster; and the reliability of the supply chains for critical goods. For all three of these factors, the U.S. is heading in the wrong direction. In many ways, Americans are becoming more vulnerable by the day.

  • Understanding the Gulf Coast's interconnected natural and human system

    The physical and ecological systems, people, and economy in the Gulf Coast are inextricably linked. Improved understanding of the coupled natural-human coastal system will help promote resilience of coastal communities and ecosystems under rapidly changing environmental conditions and support informed decision-making, says a new report.

  • Lessons from extreme weather events: What disasters teach us about resilience

    Extreme weather events are among the most likely causes of disasters. Every dollar spent on disaster resilience saves five dollars in future losses. Post-Event Review Capability analysis helps to identify opportunities to reduce risk and build long-term resilience. With that in mind, Zurich Insurance Group (Zurich) says it is sharing what it has learned about how individuals, businesses and communities can increase resilience to disasters.

  • Dangerous climate change is likely: Study

    New study reveals sensitive regions of the world are still at risk from the dangerous and potentially irreversible effects of climate change. Research also concludes governments can achieve the goals set by the 2015 Paris Climate Agreement of limiting the increase in global average temperatures to well below 2°C, if they act now.

  • Houston and Hurricane Harvey: The lessons

    Hurricane Harvey made landfall near Rockport, Texas on 25 August 2017 as a Category 4 storm. Over the next four days, Harvey dropped more than 40 inches of rain over eastern Texas, causing catastrophic flooding. The resulting floods inundated hundreds of thousands of homes, displaced more than 30,000 people and prompted more than 17,000 rescues. Total damage from the hurricane is estimated at $125 billion. Through extensive interviews, a new Post-Event Review Capability (PERC) study identifies lessons learned from the 2017 Houston floods and provides recommendations for enhancing flood resilience - before the next event occurs.

  • Climate change will soon hit billions of people, and many cities are taking action

    By mid-century, billions of people in thousands of cities around the world will be at risk from climate-related heat waves, droughts, flooding, food shortages and energy blackouts, but many cities are already taking action to blunt such effects, says a new report from a consortium of international organizations.

  • As coastal communities face more frequent, severe disruptions, costly choices loom

    Sea levels are rising. Tides are inching higher. High-tide floods are becoming more frequent and reaching farther inland. And hundreds of U.S. coastal communities will soon face chronic, disruptive flooding that directly affects people’s homes, lives, and properties. Long before rising seas permanently submerge properties, millions of Americans living in coastal communities will face more frequent and more severe disruptions from high-tide flooding. As this flooding increases, it will reach a threshold where normal routines become impossible and coastal residents, communities, and businesses are forced to make difficult, often costly choices.

  • Global warming accelerating rise in sea levels

    A new study discovered that rising sea levels could be accelerated by vulnerable ice shelves in the Antarctic. The study discovered that the process of warmer ocean water destabilizing ice shelves from below is also cracking them apart from above, increasing the chance they’ll break off. “This study is more evidence that the warming effects of climate change are impacting our planet in ways that are often more dangerous than we perhaps had thought,” said one researcher.

  • Tensions among fishing countries rise as climate change drives fish to new habitats

    Out-of-date fisheries regulatory system has not kept up with the realities of global warming and shifting fish populations. New fisheries are likely to appear in more than seventy countries all over the world as a result of climate change. History has shown that newly shared fisheries often spark conflict among nations. Conflict leads to overfishing, which reduces the food, profit and employment fisheries can provide, and can also fracture international relations in other areas beyond fisheries.

  • Worry: Hurricanes are slowing down

    Some hurricanes are moving more slowly, spending increased time over land and leading to catastrophic local rainfall and flooding, according to a new study. The speed at which hurricanes track along their paths — their translational speed — plays a role in the damage and devastation they cause. Their movement influences how much rain falls in a given area. This is especially true as global temperatures increase. “The rainfalls associated with the ‘stall’ of 2017’s Hurricane Harvey in the Houston, Texas, area provided a dramatic example of the relationship between regional rainfall amounts and hurricane translation speeds,” says one researcher. “In addition to other factors affecting hurricanes, like intensification and poleward migration, these slowdowns are likely to make future storms more dangerous and costly.”

  • Coastal communities: Record number of high tide flooding days last year

    People living on the coast may see flooded sidewalks and streets more frequently this year due, in part, to El Nino conditions that are predicted to develop later this year, and from long-term sea level rise trends. Increased flooding trend is likely to continue: The projected increase in high tide flooding in 2018 may be as much as 60 percent higher across U.S. coastlines as compared to typical flooding about 20 years ago, according to NOAA scientists.

  • Contiguous U.S. had its warmest May on record

    Last month, the U.S. sizzled with record warmth. The average May temperature across the contiguous U.S. was 65.4 degrees F, 5.2 degrees above average, making it the warmest May in the 124-year record. This surpassed the previous record of 64.7°F set in 1934, during the dust bowl era. Each state was warmer than average, and Eastern U.S. saw record precipitation.

  • Economic models significantly underestimate climate change risks: Experts

    Policymakers are being misinformed by the results of economic models that underestimate the future risks of climate change impacts, according to a new study. The researchers say that “mounting evidence” that the “integrated assessment models” used by economists “largely ignore the potential for ‘tipping points’ beyond which impacts accelerate, become unstoppable, or become irreversible.” As a result “they inadequately account for the potential damages from climate change, especially at moderate to high levels of warming,” due to rises in global mean temperature of more than 2 Celsius degrees.
