How Climate Change Contributes to Global Violence
Whether through drought, extreme heat waves, food insecurity, lack of potable water, changing disease vectors or any number of other impacts, large swaths of the globe will increasingly suffer from unhealthy and dangerous conditions brought about by climate change. Climate change can amplify intolerance and persecution and facilitate violent conflict, including war and genocide. Collective violence doesn’t just erupt spontaneously but is brought about by specific triggers and situations, and many of these relate to the consequences of climate change.

Historical Analysis Finds No Precedent for the Rate of Coal, Gas Power Decline Needed to Limit Climate Change to 1.5C
Limiting climate change to the 1.5°C target set by the Paris Climate Agreement will likely require coal and gas power use to decline at rates that are unprecedented for any large country, an analysis of decadal episodes of fossil fuel decline in 105 countries between 1960 and 2018 shows.

Extreme Rain Heads for California’s Burn Scars, Raising the Risk of Mudslides – This Is What Cascading Climate Disasters Look Like
Wildfires strip away vegetation and leave the soil less able to absorb water. A downpour on these vulnerable landscapes can quickly erode the ground as fast-moving water carries debris and mud with it. Wildfires strip away vegetation and leave the soil less able to absorb water. A downpour on these vulnerable landscapes can quickly erode the ground as fast-moving water carries debris and mud with it. Such consecutive events lead to human disasters. Studies show climate change is raising the risk of multiple compound disasters.

Biden Administration Places Climate Change at the Center of U.S. Security Planning
The administration on Thursday has released a series of reports addressing the increasingly severe impact of climate change on U.S. national security – an impact which is only going to grow in severity and scope. Taken together, the reports signal a new stage in U.S. policy, one which places climate change at the center of the U.S. security planning.

Rising Temperatures Reshaping, Exacerbating Global Security Landscape
More than just altering the environment, climate change is threatening to permanently and dangerously reshape the global security landscape. These are the conclusions of a series of new assessments by U.S. military, intelligence, and security officials. “As climate change converges with other drivers — especially geostrategic competition, emerging technology and global-demographic trends — it is reshaping the risk landscape,” DHS said in its assessment. “The corrosive impact of these trends will make nations increasingly vulnerable to domestic instability, with sweeping implications for regional and border security and core national security interests.”.

Urbanites Face Heightened Flood Risk as a Result of Forest Loss
The devastating impact of flooding in Queensland’s north, exacerbated by forest loss, is badly affecting urban areas. Researchers found that deforestation near urban areas exposes these areas to much larger amounts of water flowing on the soil surface soon after a rainfall.

Cities Worldwide Aren’t Adapting to Climate Change Quickly Enough
Climate change is magnifying threats such as flooding, wildfires, tropical storms and drought. cities are quickly becoming more vulnerable to extreme weather events and permanent shifts in their climate zones. The problem is that the pace of climate change is accelerating much more rapidly than urban areas are taking steps to adapt to it.

Urban Areas More Likely to Have Precipitation-Triggered Landslides
Urban areas may be at greater risk for precipitation-triggered landslides than rural areas, according to a new study that could help improve landslide predictions and hazard and risk assessments. Researchers found that urban landslide hazard was up to 10 times more sensitive to variations in precipitation than in rural areas.

The long view
Huge Areas May Face Possibly Fatal Heat Waves if Warming Continues
A new assessment warns that if Earth’s average temperature reaches 2 degrees C over the preindustrial average, widespread areas may become too hot during extreme heat events for many people to survive without artificial cooling.
