The relentless and disturbingly frequent occurrence of high temperatures in the Southwest region of the United States has been a subject of widespread concern and confusion. Despite the obvious role played by expansive deserts, which should be a clear indicator of such climatic patterns, there is a persistent oversight and misunderstanding. This article delves into the specific geophysical and historical factors contributing to these persistent high temperatures, while also addressing the pervasive issue of climate misinformation, particularly from government agencies.
Understanding the Geophysical Factors
The U.S. Southwest region, located at a southerly latitude, is geophysically positioned to experience high temperatures due to its proximity to the subtropical region. This is a globally recognized phenomenon where air that rises in the tropics further south sinks to the ground, leading to a warm, dry belt between 20 and 30 degrees of latitude North and South.
According to the well-known Santa Ana winds, sinking air warms at a rate of approximately 1 degree Celsius for every 350 feet of descent. This warming air leads to a cloud-free area, much like the effect of a hairdryer on hair. Consequently, the clear, dry sky during these periods allows for intense solar radiation, further heating the ground and creating a locally warm environment.
It is important to note that this belt of clear, dry weather moves around yearly, leading to varying weather patterns. During summer, this belt moves further north, while in winter, it moves further south. This explains why some areas in the Southwest experience colder winters, as they temporarily drop out of the warm, dry air and transition into the “Westerlies” that occasionally bring cold fronts.
Global Warming and Its Impact
However, the ongoing reality of global warming is significantly altering the normal patterns of climate in the Southwest. Research has shown that the area of rising air in the tropics is expanding, leading to a southward and northward shift of the dry subtropical belt. This shift translates to warmer and drier winters in regions such as Arizona, where historically, colder weather was more common.
Moreover, adjacent areas in Northern Mexico are also experiencing warmer winters, a trend that suggests a broader regional impact. Even sea temperatures in the Sea of Cortez and Gulf of California are reflecting this warming trend, further enhancing the overall warming of the interior Southwest.
The Role of Government Agencies and Climate Misinformation
The persistent climate misinformation, spearheaded by various government agencies, has exacerbated the public’s confusion and complacency. For instance, the claim that heat waves are getting worse has been repeatedly debunked by the Environmental Protection Agency (EPA) and other reputable sources. These agencies have acknowledged that the claims have been false since the 1970s, yet continue to propagate them.
There is a growing demand for a RICO investigation into climate racketeering by the White House and affiliated government agencies. The evidence to support such an investigation is overwhelming, as the agencies have known the inaccuracies but continued to mislead the public, potentially with self-serving motives.
Conclusion
The high temperatures in the Southwest region are a complex interplay of geophysical factors, annual climate patterns, and the alarming effects of global warming. While the contrast between local climate perceptions and reality is stark, it is crucial to understand the underlying mechanisms. Simultaneously, the responsibility to correct climate misinformation and hold accountable those who mislead the public must be taken seriously. Only through informed public education and accurate climate analysis can we effectively address and adapt to these environmental challenges.
