最近全球变暖的一个影响是，它正在帮助一些疾病更容易传播和传播给更多的人。蚊子是致命热带病的主要传播媒介。这些疾病通常被称为疟疾、霍乱和登革热。一个€œMalaria疫情通常局限于冬天的最低温度达到不低于16度Celsiusa€(救人),据世界自然基金会,一个独立的保护组织。科学家们开始注意到，疟疾疫情发生在正常地区之外，并将其归咎于全球变暖导致的气温升高。美国国内甚至出现了更多的疟疾病例。美国的夏天比往常更热更潮湿，我可以发誓，疟疾蚊子在炎热潮湿的天气里会大量繁殖。气温升高和更多的降雨会导致炎热潮湿的天气，如果地球继续变暖，疟疾将蔓延到更多的新地方。一项研究表明，如果大气中的温室气体浓度达到工业革命(阻止全球变暖的运动)以来二氧化碳浓度的两倍，疟疾的传播将从全球的45%增加到60%。霍乱和登革热也对新种群构成威胁，因为它们也是由在湿热天气大量繁殖的蚊子携带的。与疟疾一样，由于蚊子的迁徙，更多的霍乱和登革热疫情正在发生。这些是目前全球变暖最危险的影响，因为与所有其他讨论的影响不同，这些疾病可以在两周内杀死人类，它们可以像野火一样蔓延。

A recent impact of global warming is that it is helping some diseases spread easier and to more people. Mosquitoes are a major carrier of deadly tropical diseases. These diseases are commonly known as malaria, cholera, and dengue fever. “Malaria outbreaks are usually confined to where the minimum winter temperature reaches no lower than 16 degrees Celsius” (To Save Lives), according to the Worldwide Fund for Nature, an independent conservation organization. Scientists are beginning to notice that malaria outbreaks are occurring outside the normal areas and are attributing this to increased temperatures from global warming. States inside the U.S. have even had more cases of malaria. Summers in the U.S. are getting more hot and humid than usual, I can vow for this, and malaria mosquitoes thrive in hot and humid weather. Increased temperatures and more rain cause hot and humid weather and if the earth continues to get warmer, malaria will spread to even more new places. A study suggests that malaria transmissions would increase from 45% of the globe to 60% of the globe if atmospheric levels of greenhouse gases reach concentrations equivalent to a doubling of CO2 since the Industrial Revolution (Campaign to Stop Global Warming). Cholera and dengue fever also pose threats to new populations because they too are carried by mosquitoes that thrive in hot and humid weather. As with malaria, more cholera and dengue fever outbreaks are occurring because of migrating mosquitoes. These are the most dangerous effects of global warming right now because unlike all the other effects discussed, these diseases can kill humans within a two-week time and they can spread like wildfire.
