California is burning, a Category 4 hurricane with winds of 150 mph just blasted into the Louisiana coast, and nearly 180,000 are reported dead from a viral outbreak that is just a harbinger of what one scientist calls “a new pandemic era” driven in part by our changing climate and wanton destruction of ecosystems. While there are positive indicators that people are waking up to the growing threat of climate change, a much greater pace and scale of climate action is needed to stave off its worst effects. Riskthinking.ai provides clients with forward-looking scenarios tools that render a deeper understanding of the true cost of climate risk, in order to drive timely decision-making.
Ice sheets in Greenland and Antarctica whose melting rates are rapidly increasing have raised the global sea level by 1.8cm since the 1990s, and are matching the Intergovernmental Panel on Climate Change’s worst-case climate warming scenarios. Understanding the likelihood and implications of climate scenarios like this one is vital for planning effective responses, and is at the heart of what we do at Riskthinking.ai.
Arctic sea ice is itself an endangered species. Next month its extent will reach its annual minimum, which is poised to be among the lowest on record. The trend is clear: Summer ice covers half the area it did in the 1980s, and because it is thinner, its volume is down 75%. With the Arctic warming three times faster than the global average, most scientists grimly acknowledge the inevitability of ice-free summers, perhaps as soon as 2035. “It’s definitely a when, not an if,” says Alek Petty, a polar scientist at NASA’s Goddard Space Flight Center.
Firefighters battled nearly two dozen wildfires in California yesterday after a week of raging blazes blackened more than 1 million acres across the state. The rapidly spreading fire, which has killed five people, destroyed more than 1,000 structures and forced thousands to flee, is the result of hotter temperatures, less dependable precipitation and snowpack that melts sooner leading to drier soil and parched vegetation, shows how climate change is affecting the nation’s most populous state.
Between 1994 and 2017, an incredible 28 trillion tonnes (31 trillion tons) of ice was lost from the Earth’s ice sheets, glaciers, and mountains, according to a new report in the journal The Cryosphere. The extent of this worldwide melting has been described as “staggering” by the study authors, who warn that the ongoing loss of ice could lead to catastrophic rises in sea levels.
Researchers from University College London, Leeds University, and Edinburgh University studied satellite data in order to determine global changes in ice coverage over several decades. Speaking to The Guardian, study author Andrew Shepherd explained that “in the past researchers have studied individual areas – such as the Antarctic or Greenland – where ice is melting. But this is the first time anyone has looked at all the ice that is disappearing from the entire planet.”
Recent improvements to observational data, our understanding of the main contributing processes to sea-level change and methods for estimating the individual contributions, reconcile summed contributions of ice-mass loss, terrestrial water storage and thermal expansion of the ocean with observed changes in global-mean sea level. The methods described in this paper will contribute to improvements in projections of future sea-level change.
As wildfires around the world burn hotter, longer, and more frequently as a result of climate change, the damage to the microbial communities in soil is only just coming to light. Desertification will have serious ecological and economic consequences and is one of the many climate change risk factors that Riskthinking.ai prices to induce better mitigation and adaptation responses.
The Arctic sea ice is melting faster than climate models had predicted, researchers at the University of Copenhagen warned on Tuesday. A recent study from Britain’s University of Lincoln concluded that Greenland’s ice melt alone is expected to contribute 10-12 centimetres to the world’s rising sea levels by 2100. Another group of researchers recently concluded that the melting of Greenland’s ice cap has gone so far that it is now irreversible, with snowfall no longer able to compensate for the loss of ice even if global warming were to end today.
We agree with the Resilient St. John’s Climate Plan – “Climate change continues to be the biggest challenge of our generation. As with COVID-19, we also need to flatten the global warming curve before it’s too late.” To do so, city officials, planners and members of the business community need the kinds of scenarios and analyses tools that Riskthinking.ai has developed for better understanding climate and COVID-19 related risks.
On the heels of an unprecedented wildfire season, climate is yet again a hot topic in Australia. In a new study, researchers examine the performance and projections of the latest generation of global climate models for the Australian continent.
