A recent article in the New York Times (NYT), \u201cCases of Mosquito-Borne Chikungunya Virus Are Surging Globally: What to Know<\/a>,\u201d claims climate change is causing the the spread of mosquito-borne diseases by expanding mosquitoes\u2019 ranges. This is a scientifically unsubstantiated claim. The truth, grounded in actual data and entomological science, is that the spread of mosquitoes\u2014and the viruses they sometimes carry\u2014is closely tied to human activity, urbanization, and global transportation than to incremental changes in temperature and climate.<\/p>\n\n\n\n

\u201cA mosquito-borne virus that can leave infected people debilitated for years is spreading to more regions of the world, as climate change creates new habitats for the insects that carry it,\u201d writes the NYT. \u201cClimate change is driving the spread of chikungunya-carrying mosquitoes.<\/p>\n\n\n\n

\u201cA warmer, wetter world provides more suitable habitat,\u201d continues the NYT. \u201cAnd extreme weather events can cause more breeding in floods\u2014or displace people, who cluster in areas with poor water and sanitation supply,\u201d the NYT says.<\/p>\n\n\n\n

It sounds dramatic, but the evidence undercuts this simplistic narrative. Let\u2019s look at the facts.<\/p>\n\n\n\n

First, let\u2019s dispense with the notion that mosquitoes are creatures of the tropics alone, kept in check only by the beneficent hand of a stable, cool, climate. Global average temperatures are not a limiting factor for mosquitoes, and the recent modest change in the global average temperatures hasn\u2019t opened up new areas for colonization that weren\u2019t amenable to mosquito habitation previously.<\/p>\n\n\n\n

There are more than 3,500 species of mosquitoes, many of which are perfectly at home in cold climates. In fact, mosquitoes exist as far north as the Arctic Circle. As documented by the Alaska Department of Fish and Game<\/a>, there are over 35 species of mosquitoes in Alaska alone, some of which are legendary for their size and abundance. The notorious Aedes communis<\/em> mosquito is found well into northern Canada and Alaska, where summer temperatures remain cool. If climate were the limiting factor, Alaska would be a mosquito-free paradise. Instead, anyone who has camped there in June knows better.<\/p>\n\n\n\n

Malaria carrying mosquitoes were endemic to North America and Europe, spreading the disease, until modern interventions, primarily the use of DDT, ended the domestic spread of the disease. The vast body of scientific literature detailed in Chapter Four of Climate Change Reconsidered II: Fossil Fuels<\/a>, including studies from Africa, to England and Wales, to North and South America, to Thailand and beyond find no link between human climate change and the spread of malaria, Dengue fever, West Nile virus, and other vector-borne diseases.<\/p>\n\n\n\n

Even the Aedes albopictus<\/em> (\u201cAsian tiger mosquito\u201d) and Aedes aegypti<\/em>\u2014the supposed climate-driven villains in the NYT story\u2014long ago adapted to temperate zones. The Aedes albopictus<\/em> is found in parts of Europe, including southern Germany, Switzerland, and even Paris. Meanwhile, Aedes vexans<\/em>, another common vector, is found from the subtropics to Scandinavia.<\/p>\n\n\n\n

If warming were truly the driving factor, we would not see mosquitoes comfortably inhabiting places with chilly summers and freezing winters. Instead, mosquitoes survive cold months as eggs or larvae in frozen water, hatching out when temperatures rise above 50\u00b0F (10\u00b0C)\u2014that huge seasonal temperature swing is far greater than any climate induced temperature  change.<\/p>\n\n\n\n

The real reasons for the spread of mosquitoes and mosquito borne diseases are urbanization, infrastructure, transportation, pest-control measures (or lack thereof), and globalization.<\/p>\n\n\n\n

Epidemiological and vector studies<\/a> repeatedly show that mosquito range and the spread of mosquito-borne disease are closely tied to human movement<\/a> and the expansion of urban areas<\/a>. Mosquitoes, especially Aedes aegypti<\/em>, thrive in cities where standing water collects in artificial containers\u2014discarded tires, flowerpots, gutters, and neglected infrastructure such as seen below.<\/a><\/p>\n\n\n\n

\"A
Old tire indicating breeding ground for mosquito<\/em><\/figcaption><\/figure>\n\n\n\n

This urban mosquito is a product of globalization and poor city planning, not climate change.<\/p>\n\n\n\n

In fact, Aedes albopictus<\/em>\u2014found across much of Europe and the U.S.\u2014made its way from Asia in shipments of used tires and ornamental plants. The Centers for Disease Control and Prevention (CDC) note that the spread of this species to new regions \u201cwas primarily through the international trade in used tires<\/a>\u201d by way of human commerce.<\/p>\n\n\n\n

Even the World Health Organization (WHO) recognizes that increased travel and trade are responsible for the global spread<\/a> of chikungunya and other arboviruses. As Climate Realism<\/em> highlights in multiple articles<\/a>, \u201cthe principal drivers of expanding mosquito range are not temperature or rainfall, but rather the global shipping industry, the proliferation of artificial water containers in urban environments, and ineffective public health measures.\u201d<\/p>\n\n\n\n

Furthermore, Climate at a Glance<\/em> points out<\/a> that \u201cthe resurgence of mosquito-borne diseases in recent decades has much more to do with reduced mosquito control efforts, population growth, and increased urbanization than with any small change in climate.\u201d<\/p>\n\n\n\n

The NYT, as with many other mainstream media outlets, defaults to climate change as the cause of any global health phenomenon, because it advances their preconceived belief such phenomena stem from human greenhouse gas emissions causing dangerous climate change. Rather than dig into the messy details of urban water management, the tire trade, the eradication of the powerful but safe insecticide DDT<\/a>, and failing mosquito control programs, the NYT simply hoists the \u201cwarming climate\u201d flag and moves on.<\/p>\n\n\n\n

The NYT ignores the real culprits responsible for the expansion and in some cases resurgence of mosquito-borne diseases in Northern latitudes, the well-documented roles of: global transportation; international trade, especially in used tires; the discontinuation of effective chemical eradication efforts; and urbanization.<\/p>\n\n\n\n

The facts are out there, free for the taking, if one cares to look. The NYT could have talked to any number of entomologists, epidemiologists, or even\u2014heaven forbid\u2014read the CDC or WHO reports, and they would have discovered that \u201cclimate change\u201d is, at best, a minor player in this story.<\/p>\n\n\n\n

History and science show mosquitoes and the diseases they spread will always find a way\u2014regardless of the global thermometer reading. History also shows that direct eradication and prevention efforts can be effective in suppressing mosquitoes and the diseases they can spread. By contrast, attempting to halt the spread of mosquito-borne diseases indirectly, by suppressing fossil fuel use to cut carbon dioxide emissions in the vain hope this will control future temperatures, will do nothing to save lives today or in the future. If the NYT had made this point, it would have done a true public service to its readers.<\/p>\n\n\n\n
