According to the image above, the major impact to climate change is the biological systems. The key regional risks in North America, where Mexico is located in, is the wildfire-induced loss of ecosystem integrity, property loss, human morbidity, and mortality, as a result of increased drying and temperature trend. Another key risk is the heat-related human mortality. Lastly, Ubran floods in riverine and coastal areas, inducing property and infrastructure damage; supply chain, ecosystem, and social system disruption; public health impacts, and water quality impairment, due to sea level rise, extreme precipitation, and cyclones.
Regional Climate Projections.
As I read the document in the website http://www.climatechange2013.org/report/full‐report/ under North America, I have learned that the NAMS brings excess summer rainfall to Central America and Mexico. Also, A high-resolution regional Ocean GCM using a CMIP3 ensemble for boundary conditions confirms that the Intra American Seas circulation weakens by similar rate as the reduction in Atlantic Meridional Overturning. This weakening causes the Gulf Mexico to warm less than other oceans. From October to March, ensemble mean projection indicate precipitation decrease in northern Central America, including Mexico. In the Carribean precipitation is projected to decrease in the south but to increase in the North. This warming generally leads to a two- to four fold increase in simulated heat wave frequency over the 21st century.
Detailed Look at Future Climate.
In North America's climate where Mexico is located, climate has changed and some societally relevant have been attributed to anthropogenic causes. Some of the recent climate changes and individual extreme events that has happened demonstrated both impacts of climate-related stresses and vulnerabilities of exposed systems. Many climate stresses that carry risks are particularly related to sever heat, heavy precipitation, and declining snow pack. This will increase in frequency and or severity in North America in the next decades. Global warming of approximately 2C is likely to lead to more extreme heat events and daily precipitation extremes over most area of North America, affecting Mexico. North American ecosystems are under increasing from rising temperatures, carbon dioxide (CO2) concentrations, and sea levels, and are particularly vulnerable to climate extremes. Human health impacts from extreme climate events have been observed. Observations impacts on livelihoods, economic activities, infrastructure, and access to services in North American urban and rural settlements.
Most Interesting Threat.
The most interesting threat that I got out of this article was how these storms and heat events can cause health risks. Human health is the most delicate and imperative part of life that everyone has to take care of. But how do we take care of our health if these sporadic storms and extreme heat come and make it difficult for us to take care of ourselves. Some storms will also give you diseases after the storm has passed and having you keep it for a while.
Some of the dangers that come after a storm or a natural disaster would be a water-borne diseases. The people at risk for water-borne disease would be among the poor, infants, elderly, pregnant women, and immune compromised indiciduals. In Mexico City, declining water quality has led to ineffective disinfection of drinking water supplies. Changes in temperature and hydrological cycles can influence the risk of water-borne diseases.
