Hottest January on Record Globally but it was Cold in USA

Hottest January on Record Globally but it was Cold in USA

Climate Change - January 2025 Anomalies and Emerging Explanations

January 2025 presented a paradox: while the contiguous United States experienced its coldest January in 37 years, the planet as a whole recorded its warmest January on record, continuing a trend of extreme heat observed over the past two years. This anomaly has intensified concerns among scientists, leading to investigations into potential contributing factors beyond El Niño and decreased aerosol pollution. Emerging research suggests that declining cloud cover, potentially driven by a feedback loop linked to warming temperatures, may be playing a significant role in the accelerating rate of global warming. The implications of these findings, coupled with concerns about the climate's sensitivity to carbon loading and the potential for exceeding established warming targets, are prompting consideration of controversial solutions like Solar Radiation Modification (SRM).

Main Themes & Key Ideas:

  1. Contrasting Regional and Global Temperatures:
  • The contiguous U.S. experienced a notably cold January 2025. According to NOAA, it was "the Lower 48's chilliest January since 1988... 0.89 degrees Fahrenheit colder than the 20th century January average." Some cities in the Southeast experienced their top 10 coldest Januaries.
  • Despite this regional cold, globally, January 2025 was the warmest on record, surpassing the previous record set just one year prior. According to the European Copernicus Climate Change Service (C3S), January 2025 was the planet's warmest January.
  • This occurred despite a weak La Niña, which typically has a cooling effect on global temperatures. "Perhaps what was so stunning about this was it happened during a weak La Niña."
  1. Acceleration of Global Warming and Scientific Concern:
  • The record-setting temperatures represent a continuation of a trend observed since June 2023, leading scientists to express concern and even alarm. "The world set another monthly heat record in January. That may sound like something we’ve heard a lot lately, but this latest record has scientists mysti ed, surprised and even 'terri ed.'"
  • The consistency of record heat is described as "anomalous even by the standards of the last two years." Some scientists use adjectives like "surprising," "unexpected" or "anomalous."
  • James Hansen's research indicates an underestimated pace of global warming, accelerating by more than 50% in the last few years. The team expects that 1.5°C is now pretty much the climate’s baseline.
  1. Cloud Cover and Planetary Albedo:
  • Two new studies suggest that declining cloud cover contributes to the acceleration of global warming. The Washington Post reports: "Two new studies offer a potential explanation: fewer clouds. And the decline in cloud cover, researchers say, could signal the start of a feedback loop that leads to more warming."
  • Reduced low-altitude cloud cover has decreased the Earth's reflectivity (albedo). "They found that low-altitude cloud cover has fallen dramatically — which has also reduced the reflectivity of the planet. The year 2023 — which was 1.48 degrees Celsius above the preindustrial average — had the lowest albedo since 1940."
  • One study estimates that decreased albedo contributed 0.2 degrees Celsius of warming to 2023's record temperatures. "That low albedo, Goessling and his co-authors calculated, contributed 0.2 degrees Celsius of warming to 2023’s record-high temperatures."

Valencia Deadly Flash Flood: Latest in a String of Floods that Seem to be Getting More Frequent & More Severe

Valencia Deadly Flash Flood: Latest in a String of Floods that Seem to be Getting More Frequent & More Severe

Meteorology Matters explores the devastating consequences of flooding across the globe, highlighting the increasingly frequent and intense events driven by climate change. We examine how different countries are responding to this challenge, focusing on strategies such as building barriers, adapting to flooding, and relocating communities. We look at the World Weather Attribution report that analyzes the recent flooding in Sudan, concluding that human-induced climate change has significantly increased the likelihood of such extreme rainfall events. There’s been a record-breaking number of flash flood emergencies in the US, emphasizing the role of climate change in intensifying heavy rainfall events. The damage inflicted by Tropical Storm Helene on the Great Smoky Mountains National Park, showcases the destructive power of flooding on natural landscapes and infrastructure. Recently severe flooding in Italy and Spain, show the significant human and economic toll these events have taken. We address the unfolding tragedy in Valencia, Spain, highlighting the devastating impact on the country and the ongoing efforts to provide aid and rescue stranded individuals.

Multiple Hurricane Strikes in Florida is Normal, Not Climate Change

Multiple Hurricane Strikes in Florida is Normal, Not Climate Change

Urology matters uncovers the history of hurricanes in Florida, particularly focusing on the significant impact of the 1848 Tampa Bay hurricane. There have been many years with multiple major hurricane landfalls in Florida, highlighting the state's vulnerability to these natural disasters. We also look the 2024 and recent hurricane seasons, analyzing the frequency and intensity of storms in relation to climate change, while also acknowledging that hurricanes are a natural part of Florida's coastal environment. The 1848 Tampa Bay hurricane had devastating effects on the region and its lasting impact on the local geography but the population in the area was very small at the time. Additionally, discuss how Florida has always been a hurricane hot spot, but only in the last half century has the population blossomed along the coast to really affect massive numbers of people and damage the more developed infrastructure.

FEMA - National Flood Insurance Program’s 50% Rule

FEMA - National Flood Insurance Program’s 50% Rule

Meteorology Matters breaks down the Federal Emergency Management Agency's (FEMA) "50% rule," a regulation that impacts homeowners in flood-prone areas. This rule states that if a home (structure itself excluding the land) sustains damage exceeding 50% of its market value, it must be brought into compliance with current floodplain management standards, usually by elevating the structure. The rule is designed to discourage rebuilding vulnerable properties in flood zones and prevent the government from bearing the cost of repeated damage. The sources explain the details of the rule, how it is applied, and the debate surrounding its implementation, particularly in Florida, where communities face an ongoing threat of hurricanes and rising sea levels. Homeowners and local officials often find themselves in a difficult position, balancing the need for rebuilding with the financial burden of complying with the rule, which can make it challenging to afford housing in flood-prone areas.
