Waste of Space: A Proactive Approach to Removing Space Junk
There are more than 27,000 pieces of space debris bigger than the size of a softball currently orbiting Earth, and they are traveling at speeds of up to 17,500 mph, fast enough for a small chunk to damage a satellite or spacecraft like an intergalactic cannonball. Cleaning up this space junk will be an important task if agencies are to shoot more rockets and satellites into orbit.

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.

France Sets to Invest in Small Modular Nuclear Reactors
France plans to invest in small modular nuclear reactors (SMRs). Some experts question whether this is ecologically and economically sensible, but it may be that France’s interests in SMRs is as much about geopolitical strategy as it is about energy.

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.

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.

Canals Can Help the U.K. Cope with the Climate Problems
The presence of canal water can cool urban areas by up to 1.6°C during heatwaves in a 100-metre-wide corridor along the waterway. Research shows that the U.K.’s 200-year-old canals offer huge ‘blue’ opportunities to help Britain tackle the climate change crisis by helping cool homes and businesses, mitigating floods, and generating electricity through hydro generators.

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.

Fighting Floods with Restoration Versus Riprap
While both natural and man-made systems have their limits, gray infrastructure—seawalls, jetties, levees—comes with high maintenance costs, can increase erosion, or may even unintentionally retain water. Incorporating green infrastructure—beaches, dunes, islands, wetlands—into flood protection plans alongside gray infrastructure can shield communities, reduce maintenance, and provide additional social and environmental benefits.

Water Wars: A Historic Agreement Between Mexico and US Is Ramping Up Border Tension
As climate change drives rising temperatures and changes in rainfall, Mexico and the US are in the middle of a conflict over water, putting an additional strain on their relationship. Partly due to constant droughts, Mexico has struggled to maintain its water deliveries for much of the last 25 years, deliveries to which it is obligated by a 1944 water-sharing agreement between the two countries.
