• Reducing Risk, Empowering Resilience to Disruptive Global Change

    Five-hundred-year floods. Persistent droughts and heat waves. More devastating wildfires. As these and other planetary perils become more commonplace, they pose serious risks to natural, managed, and built environments around the world. Assessing the magnitude of these risks over multiple decades and identifying strategies to prepare for them at local, regional, and national scales will be essential to making societies and economies more resilient and sustainable. A workshop highlights how MIT research can guide adaptation at local, regional, and national scales.

  • Sea Level Rise: Major Economic Impact in the Absence of Further Climate Action

    Rising sea levels, a direct impact of the Earth’s warming climate, is intensifying coastal flooding. The findings of a new study show that the projected negative economy-wide effects of coastal flooding are already significant until 2050, but are then predicted to increase substantially towards the end of the century if no further climate action on mitigation and adaptation is taken.

  • Climate Costs Smallest If Warming Is Limited to 2°C

    Climate costs are likely smallest if global warming is limited to 2 degrees Celsius. The politically negotiated Paris Agreement is thus also the economically sensible one, Potsdam researchers find in a new study. Using computer simulations of a model by U.S. Nobel Laureate William Nordhaus, they weight climate damages from, for instance, increasing weather extremes or decreasing labor productivity against the costs of cutting greenhouse gas emission by phasing out coal and oil. Interestingly, the economically most cost-efficient level of global warming turns out to be the one more than 190 nations signed as the Paris Climate Agreement. So far however, CO2 reductions promised by nations worldwide are insufficient to reach this goal.

  • 2019: Economic Losses from Natural Disasters Top $232 billion in 2019

    A new report from Aon shows that 409 natural catastrophe events of 2019 resulted in economic losses of $232 billion. Of that total, private sector and government-sponsored insurance programs covered $71 billion. The costliest individual peril was inland flooding, which caused economic losses globally of $82 billion, followed by tropical cyclone, at $68 billion.

  • Climate Change Means the U.S. Must Start Building Big Things Again

    There used to be a time when the United States was adept at planning and building big projects – the highway system, putting a man on the moon, and more. Not anymore, James Temple writes. He notes that nearly every giant infrastructure project in the United States suffers from massive delays and cost overruns, and this is when they are not shut down altogether before completion. “The U.S. has become terrible at building big things, and negligent in even maintaining our existing infrastructure,” he writes, adding: “That all bodes terribly for our ability to grapple with the coming dangers of climate change, because it is fundamentally an infrastructure problem.”

  • Before We Rush to Rebuild after Fires, We Need to Think about Where and How

    Public support for rebuilding in the same disaster affected places is often high. But as fire-fighting agencies are aware, our bushfires are increasing in size, intensity and duration, and a warming climate will continue to worsen these factors. We need to start being more strategic about where we rebuild homes and facilities lost to fire, and how.

  • The Prospects of Climate Engineering

    Climate engineering may offer a last-ditch technological solution to catastrophic climate change, but who makes the decisions on which solutions to implement, and who the beneficiaries will be? Once we start fiddling with the Earth’s fundamental processes, where will it end?

  • Tropical Cyclones Causing Billions in Losses Dominate 2019 Natural Catastrophe Picture

    Natural catastrophes cause overall losses of $150 billion, with insured losses of about $52 billion. Severe typhoons in Japan cause the year’s biggest losses. Hurricane Dorian, the strongest hurricane of the year, devastates the Bahamas, but the U.S. mainland was largely spared. Humanitarian tragedy caused by cyclones in Mozambique, with more than 1,000 deaths.  – Better protection is urgently needed

  • Climate Change will Take Increasingly Heavier Toll on People’s Welfare, Security: Experts

    The World Economic Forum has just issued its annual Global Risk Report, based on input from more than 750 global experts and decision-makers, who were asked to rank their biggest concerns in terms of likelihood and impact on the welfare and security of people around the world. For the first time in the survey’s 10-year outlook, the top five global risks in terms of likelihood are all related to the environment: intensification of extreme weather events; failure of climate mitigation and adaptation; increasing human-induced damage to the environment; ecosystem collapse; growing vulnerability of more people to natural disasters such as earthquakes, tsunamis, hurricanes, volcanic eruptions, and geomagnetic storms.

  • On A Hotter Planet, We Are All Australians

    Warm the human body by 7 degrees Fahrenheit and death ensues. David Spratt writes that on the Paris Agreement emissions trajectory, the entire world is heading for around 7 degrees Fahrenheit of warming once system feedbacks are included. The Lancet wrote: “Without immediate and efficient climate action, catastrophic bushfires will become a common disaster and might destroy the future of Australia and possibly of humanity.” Spratt says: “On a hotter planet, we are all Australians, one way or another. And the fire season is far from over.”

  • The Heat Human Activity Has Added to World’s Oceans in the Past 25 Years Is Equivalent to 3.6 Billion Hiroshima-Size Bombs

    The Hiroshima atom-bomb exploded with an energy of about 63,000,000,000,000 Joules. The amount of heat mankind has put in the world’s oceans in the past 25 years equals to 3.6 billion Hiroshima atom-bomb explosions. A new analysis shows the world’s oceans were the warmest in 2019 than any other time in recorded human history, especially between the surface and a depth of 2,000 meters. The new studyalso concludes that the past ten years have been the warmest on record for global ocean temperatures, with the past five years holding the highest record.

  • 2019: 2nd Wettest Year on Record for U.S.; $14 Billion Climate Disasters

    It was another year of record-making weather and climate for the U.S. in 2019, which was the second wettest behind 1973. Fourteen billion-dollar disasters that struck the U.S. last year included Hurricane Dorian, historic flooding and severe storms.

  • The Costs of Closing Germany’s Nuclear Power Plants

    Many countries have phased out production of nuclear energy because of concerns related to nuclear waste and the risk of nuclear accidents. A new study explores Germany’s decision, after the 2011 Fukushima accident, to replace nuclear power with fossil-fuel power generation, finding that the switch to fossil fuel-fired power resulted in considerable increases in pollution at an estimated annual social cost of about $12 billion.

  • The Lessons from Australia’s Fires

    You might think that Australia is particularly vulnerable to forest fires. But that would be a mistake. Many other countries share the same conditions that have set Australia ablaze, physically and politically, including similar terrain and a leadership that has yet to wake up fully to the new reality that climate change is creating.

  • DHS Listed Climate Activist Group as “Extremists” Alongside Mass Killers

    A group of environmental activists engaged in civil disobedience targeting the oil industry have been listed in internal Department of Homeland Security documents as “extremists” and some of its members listed alongside white nationalists and mass killers. Those listed are five members of Climate Direct Action who formed what has been dubbed the Valve Turners, after closing the valves on pipelines in four states carrying crude oil from Canada’s tar sands on 11 October 2016. It was described as the largest coordinated action of its kind and for a few hours the oil stopped flowing.
