• In the world of finance, consideration of climate change is now mainstream

    As climate changes become impossible to dismiss, how does the mainstream investor community respond? Are financial decisions taking full account of risks and opportunities related to climate change, or is the topic still virtually ignored in financial decision-making?    

  • Blitz spirit needed to meet challenges like climate change: Dr. Hugh Hunt

    Today’s engineers will need the kind of drive and determination shown by the great wartime innovators such as Sir Barnes Wallis and Sir Frank Whittle if they are to respond effectively to challenges such as climate change, Dr. Hugh Hunt told the Royal Academy of Engineering on Tuesday. Hunt compared today’s challenge of adapting to future climate change with the imperative to develop new technologies to tip the balance of military capability in favor of the Allies during the Second World War.

  • Update issued for southeast Florida regional sea level rise projections

    The four-county Southeast Florida Regional Climate Change Compact (Compact) has prepared an update to the regional sea level rise projections used for important planning purposes. Overall, the update includes minor changes to the short-term curves, but a more significant increase in the mid-and long-term projections. The 2015 update estimates sea level rise of 6 to 10 inches by 2030, or 3 to 5 inches above average sea level in 2015. Predictions for the mid-term are between 11 and 22 inches of additional sea level rise by 2060, and longer-term between 28 and 57 inches by 2100.

  • New York proposes new sea-level rise projection regulations

    New York State Department of Environmental Conservation (DEC) announced last week that to better prepare New York State coastal communities and business owners for extreme weather events like Superstorm Sandy three years ago, DEC is proposing new state sea-level rise projections which will help state agencies and project planners develop more resilient structures. “The sea-level rise projections DEC is proposing today reflect the best science available,” said DEC acting commissioner. “Sea level projections will help state agencies, developers, planners and engineers to reduce risks posed by rising seas and coastal storms over the next several decades.”

  • California releases plan for preparing the state for extreme effects of climate change

    In response to a directive from California governor Edmund G. Brown Jr., the California Natural Resources Agency has been seeking public comment on a draft plan for how California will prepare for and adapt to the catastrophic effects of climate change, including extended droughts and wildfires, rising sea levels and increasingly extreme weather. The draft plan — Safeguarding California: Implementation Action Plans — identifies the state’s vulnerabilities to climate change and details steps that need to be taken across ten sectors including water, transportation, agriculture, biodiversity and habitat, emergency management, and energy.

  • Wildfires may double erosion across a quarter of western U.S. watersheds by 2050

    Wildfires, which are on the rise throughout the west as a result of prolonged drought and climate change, can alter soil properties and make it more vulnerable to erosion. A new study shows that the increase in wildfires may double soil erosion in some western United States by 2050, and all that dirt ends up in streams, clogging creeks and degrading water quality.

  • Study: Persian Gulf could experience deadly heat

    Detailed climate simulation shows that the Persian Gulf region would likely cross the threshold of survivability unless mitigation measures are taken. That tipping point involves a measurement called the “wet-bulb temperature” which combines temperature and humidity, reflecting conditions the human body could maintain without artificial cooling. That threshold for survival for more than six unprotected hours is 35 degrees Celsius, or about 95 degrees Fahrenheit, according to recently published research (the equivalent number in the National Weather Service’s more commonly used “heat index” would be about 165 F). The researchers say that hot summer conditions that now occur once every twenty days or so “will characterize the usual summer day in the future.”

  • Deadly extreme weather events to intensify, become more frequent over the next 50 years

    European heat wave of 2003, during which 35,000 people died. It was the most extreme event of its kind since 1500 AD. In May 2015, India was struck by a severe heat wave that killed more than 2,500 people. “Heat waves that [were once] expected to occur twice a century [are now], in the early 2000s, expected to occur twice a decade. Human influence has very likely at least doubled the likelihood of such an event,” says one expert.

  • Climate change will reshape global economy: Study

    Unmitigated climate change is likely to reduce the income of an average person on Earth by roughly 23 percent in 2100, according to estimates contained in a new study. The findings indicate climate change will widen global inequality, perhaps dramatically, because warming is good for cold countries, which tend to be richer, and more harmful for hot countries, which tend to be poorer. In the researchers’ benchmark estimate, climate change will reduce average income in the poorest 40 percent of countries by 75 percent in 2100, while the richest 20 percent may experience slight gains.

  • September 2015, and January-September 2015, the warmest on record

    A new report from the National oceanic and Atmospheric Administration (NOAA) finds that September 2015 was the warmest month on record, with average temperature across global land and ocean surfaces reaching 1.62°F (0.90°C) above the twentieth century average. The year-to-date temperature across global land and ocean surfaces was 1.53°F (0.85°C) above the twentieth century average. This was the highest for January–September in the 1880–2015 record.

  • U.S. should lead climate change fight to bolster global stability: U.S. defense, diplomacy leaders

    Forty-eight former U.S. leaders, both Republicans and Democrats – among them secretaries of state and defense, national security advisers, leaders of the intelligence community, diplomats, generals in all four branches of the armed services, senators, and members of the House of Representatives – have published an open letter in the Wall Street Journal which called on U.S. political and business leaders to “think past tomorrow” and lead the fight on climate change. The U.S. security establishment has long recognized the threat posed by climate change to U.S. national security, defining climate change as a “threat multiplier,” adding fuel to conflicts. Security experts and military leaders no longer regard climate change as only a threat multiplier, but rather as s serious danger on its own – with droughts, sea-level rise, food shortages, and extreme weather events triggering migration and armed conflicts.

  • California’s future: More frequent and more severe droughts and floods

    In the future, the Pacific Ocean’s temperature cycles could disrupt more than just December fishing. A new study suggests that the weather patterns known as El Nino and La Nina could lead to at least a doubling of extreme droughts and floods in California later this century.

  • Philippines coastal areas go underwater due to sea level rise

    More than 167,000 hectares of Philippines coastland — about 0.6 percent of the country’s total area — are projected to go underwater in, especially in low-lying island communities, according to research by the University of the Philippines. Low-lying countries with an abundance of coastlines are at significant risk from rising sea levels resulting from global warming. According to data by the World Meteorological Organization, the water levels around the Philippines are rising at a rate almost three times the global average due partly to the influence of the trade winds pushing ocean currents. On average, sea levels around the world rise 3.1 centimeters every ten years. Water levels in the Philippines are projected to rise between 7.6 and 10.2 centimeters each decade.

  • Managing urban stormwater runoff better

    As meteorologists monitor the El Nino condition currently gaining strength in the Pacific Ocean, Californians look with hope to the much-needed rain and snow it could yield. But if Californians are going to make the most of the precipitation, they need to put a LID on it. LIDs, or low-impact development technologies, mimic pre-urban stream functions. Examples are green roofs that absorb and evapotranspire rainfall; rainwater tanks attached to homes and other buildings; and permeable pavement for roads, driveways and parking lots. Rainwater could even be used in the home for toilet flushing and laundry.

  • IPCC projections “wildly over optimistic”: Climate expert

    As a new chairman is appointed to the Intergovernmental Panel on climate Change (IPCC), one climate expert has said headline projections from the organization about future warming are “wildly over optimistic.” The expert says that IPCC claims that “global economic growth would not be strongly effected” are unrealistic and that if we are to meet the 2°C warming target, wealthy and high emitting individuals will need to make dramatic cuts in the energy they use and in the material goods they consume  at least until the transition away from fossil fuels is complete.
