The United States faces the most destructive hurricanes more than three times as often as it did a century ago, according to a new study in the Proceedings of the National Academy of Sciences that blames the shift “unequivocally” on climate change.

Major shifts in global society will be needed to avoid “untold suffering due to the climate crisis,” according to a statement endorsed by more than 11,000 scientists from 153 nations and published this week in the journal BioScience.

Deploying a far more accurate method than has been used to date to predict future sea level rise, researchers say three times more people than previously thought will face inundation by 2050, with some of the world’s greatest cities at risk of going under the waves.

Big diesel trucks and ever more numerous sport utility vehicles (SUVs) are driving up lung-damaging emissions of small particulate matter, while producing enough extra carbon dioxide to significantly imperil efforts to hold average global warming below 2.0°C, according to a two-year study released this week by the University of Toronto’s Southern Ontario Centre for ...

A destabilized climate could lead to a precipitous decline in property values, cutting communities off from the tax base they need to fund climate adaptation while banks stop lending in areas that experience repeated floods, according to an analysis released earlier this month by the Federal Reserve Bank of San Francisco.

The 23-kilometre land link that connects Nova Scotia to the rest of Canada is at risk as climate change drives up sea levels and makes severe storms more frequent.

The world’s oceans will rise nearly one metre (three feet) by 2100, 100-year coastal storms and flooding will happen annually, fish stocks will see serious declines, snow and ice cover will diminish, and killer storms will get wetter and more powerful without fast action to reduce the greenhouse gas emissions that cause climate change, concludes ...

At least five people are dead in southeast Texas after Tropical Depression Imelda dropped up to 43 inches (1.1 metres) of rain on the region, becoming the seventh-wettest tropical cyclone in U.S. history.

The former chief monitoring officer of Alberta's Environmental Monitoring and Science Division (EMSD) is raising the alarm about the province’s decision last week to shutter the office and fold it into a new administrative structure, at the same curtailing its stand-alone climate change office, warning that the province’s monitoring of fossil-driven industrial pollution will continue ...

A steady stream of hurricane-force storms has Atlantic Canada rethinking its approach to electricity grids, shoreline defences, and even tree planting, while insurance companies brace themselves for damage claims that are set to double every five to seven years.

Countries must invest US$1.8 trillion in climate adaptation funding by 2030 to prevent a world of “climate apartheid”, in which the wealthiest pay to protect themselves from sea level rise and mounting food shortages while everyone else suffers.
