Our climate change adaptation and mitigation consulting program & fund limit global warming's impact on weather patterns and the economy.
@Avabelly__ In the US, tipping is legally optional but socially mandatory. While the rest of the world caps tips at 10% or wraps service fees into the bill, the US operates on a 18%- 25% standard expectation.Because the minimum wage is so low, servers heavily rely on tips to make a living.
The Gulf Stream could collapse as early as 2060.
A new study from Utrecht University reveals that the Atlantic Meridional Overturning Circulation (AMOC)—the engine behind the Gulf Stream—is weakening far more rapidly than earlier projections suggested. This vast ocean conveyor carries warm tropical water northward to Europe and sends cold water back south, moderating Northern Europe’s climate, sustaining global rainfall patterns, and stabilizing weather systems worldwide.
If the AMOC collapses, that equilibrium would shatter.
Researchers calculated that even under a moderate emissions pathway—limiting warming to 1.5 °C (2.7 °F) above current levels—there is a 37 % chance of AMOC failure by 2100. In high-emissions scenarios, the risk climbs to 70 %. Even the most optimistic models give a 25 % probability of collapse.
A shutdown would bring severe winters to Europe, widespread droughts, and devastating agricultural losses. Global precipitation belts would shift, and sea levels along the U.S. East Coast could surge by up to a meter or more.
In essence, the AMOC is a planetary tipping point—and we are nearer to triggering it than previously estimated.
European climate officials now label the threat a “national security priority,” yet coordinated global action remains inadequate.
The last major AMOC slowdown, 12,000 years ago, sparked abrupt regional climate swings. This time, with human societies far more interconnected, adaptation may not keep pace.
How do we confront a danger that builds over decades yet could irreversibly transform the world?
One square mile on the surface receives ~2.5 Gigawatts of solar energy. That’s Gigawatts with a “G”. It’s ~30% higher in space. The Starlink global satellite network is entirely solar/battery powered.
Factoring in solar panel efficiency (25%), packing density (80%) and usable daylight hours (~6), a reasonable rule of thumb is 3GWh of energy per square mile per day. Easy math, but almost no one does these basic calculations.
Africa's largest urban park on today's World Parks Day is in . . .
Mozambique.
And it's new. The 45,000 m² River Chiveve Park opened in 2020 in Beira, and is innovatively designed to assist with flood control.
The first park designed to mitigate Climate Change.
