The Atlantic Ocean is heating up and it's not just the usual suspects like greenhouse gases or weather patterns that could be to blame. An unexpected cause has come to light: the disappearance of certain clouds called "ship tracks." These are the low-lying, reflective clouds that ships leave in their wake (you can see them clearly in the picture above), and they've been helping to keep our planet cool. However, the 2020 regulations by the United Nations's International Maritime Organization (IMO) curtailed ships' sulfur pollution to improve air quality. While this was great for our lungs, it caused fewer ship tracks and thus a warmer Earth, particularly where there's a lot of boat traffic, like on the Atlantic.

This unintended test of geoengineering—though not in the direction we'd like—has given researchers a unique chance to study how we might influence our planet's temperature through manipulating clouds. A strategy called marine cloud brightening proposes we make clouds more reflective by pumping salt particles into the air. The drop in ship tracks has shown that this could have a significant impact on cooling the Earth.

It’s worth mentioning that sulfur clouds from ship pollution also contribute to acid rain (sulfur dioxide), so it's not a good idea to revert to old habits. We would need to find a cleaner way to make these clouds. Thankfully the idea mentioned above, marine cloud brightening, could generate reflective clouds with far less pollution.

This situation paints a picture of a complex and delicate balance between our actions and the environment. Our efforts to reduce sulfur pollution, while positive for air quality and reducing acid rain, have had an unexpected warming effect on our planet. Yet, it's also highlighted potential ways we can deliberately cool the Earth. As we continue to grapple with climate change, this underscores the importance of understanding the full impact of our decisions and the potential for innovative, environmentally-conscious solutions.

‘Suffocated to death’: Florida researchers testing water, carcasses to determine what caused fish kill (FOX 35 Orlando) - Researchers in Florida are investigating a recent fish kill in the Indian River Lagoon, with concerns that the deaths could be attributed to factors like a low oxygen event, nutrient cycle disruption, and algal blooms, while tests are being conducted to identify the toxins present and the extent of the damage.

Making a connection: Construction of Olso Road interchange with I-95 ready to get underway (TCPalm) - Construction of the long-awaited Oslo Road interchange with I-95 is set to begin in Indian River County, marking a significant project valued at $95.8 million and expected to be completed by summer 2027. The project involves partial cloverleaf ramps, widening of Oslo Road, and various infrastructure enhancements, aiming to improve economic development and emergency evacuation routes for the county. The Chamber of Commerce anticipates positive economic growth with increased access to the area. More pictures here.

The State of Florida Preempts Local Contracting Licenses. What Does This Mean to You? What’s Next? (Vero Communique) - Florida's new laws (HB 735 and HB 1383) regarding contractor licensing have preempted local contracting licenses to the state, leading to confusion and unintended consequences for Indian River County homeowners, with implications such as the inability to seek relief for fraud due to the absence of local licenses, resulting in matters now being handled through small claims court; furthermore, the loss of local control over certain contractor licensing areas and additional legislation (HB 1383) further complicates the landscape by prohibiting local governments from requiring licenses for job scopes not available at the state level, potentially leading to difficulties in identifying licensed businesses. This is a very good example of why the state's constant attacks on Home Rule need to be fought.
