Climate science has proven that the world is warming. The acceleration of that process over the last four decades is also normal. But the whole globe does not see its temperature rising at the same rate: on the American continent, the north saw a greater increase than the south; Richer countries than middle-income countries; Coastal areas, especially the Atlantic, are more inland. Although some of those trends may change.

Temperatures in North America, Central America, and the Caribbean rose by about 1.2 degrees Celsius compared to the 1950s and 1980s averages. Four-fifths of the increase occurred within a decade: in the 1990s. The hole in the ozone layer (which is declining today) and the ‘greenhouse effect’ were the main protagonists of the accurate awareness of global warming. But the gradual change in consumption patterns, particularly energy and access to better technologies, facilitated by the presence of new regulatory mechanisms, international agreements and protocols that have slowed (albeit not slowed down) the rise of the 21st century, as much as it did in the last 25 years, from 2003 to 2015. The rate of temperature rise doubled.

However, the highest increase in average temperature since the 1960s in North America, the United States, and especially in Canada, is collected at considerable distances from other countries. It is no coincidence that the two nations have achieved the highest economic development on the continent: fossil fuels are essential to unify growth and well-being, and this is the result.

As such, they continue to do so today, especially for countries that want to join the highest-income club. These nations see this as a definite redistribution imbalance, which is exactly what international limits on expulsion are already trying to achieve: when those who depend on them do not need them to achieve growth goals. Although the Paris Commitment already includes compensation mechanisms for balancing opportunities, the specification of its implementation during this period Glasgow Climate Summit Each country keeps open the conversation about the weight to be assumed to stop the heat. On the American continent, the political derivatives of this gap are particularly pronounced in the case of large countries. Mexico O Brazil, Requires more funding through a transactional approach.

But the biggest divide that can still be seen is geographical: Andean countries, regardless of their income level, have experienced the most moderate growth. La Paz (Bolivia), the highest capital on the continent, rises +0.64 degrees. Puno or Cusco in mountainous Peru is on a similar level. But to approach a more temperate or warmer climate, it is enough to go a little further north so that the figures increase to two: Medellin (Colombia), Guayaquil (Ecuador) or practically cities. All capitals are Central America.

In fact, coastal exposure, especially on temperate fringes, is most strongly determined by its strong rise in temperature on its eastern slopes (coasts facing the Atlantic). Thus, the entire New England urban waterfront from Edison to Boston has grown by +2.8 degrees over the past sixty years. Less than Halifax, the Canadian border (+3.08 degrees), Anchorage (Alaska’s capital: +3.05 degrees), or just north of Winnipeg in the Canadian province of Manitoba, is the city of all continents. The largest increase (+3.41 degrees).

As in areas with dry climates or directly in the desert. The Mexican-American border (Phoenix, Arizona: +2.5 degrees; Rhinosa, Tamoulipas: +2.35) is a good example. Semi-arid region and northeastern Savannah also have the most significant impacts: the cities of Juiziro or Timon exceed 30% of those observed in Rio de Janeiro or Sao Paulo.

The Zoom In Brazil, when it comes down to the level of specific weather stations, it draws the general pattern more clearly, but in some areas more or less dark spots appear than expected, highlighting the inherent variation in data levels such as flush. Soil temperature.

Inevitably, the more we focus on a particular location, the more likely we are to find data that does not match the heating trend. But these particular variations do not invalidate the global trend, which is reflected in the statistics. They express only the essential features of a global phenomenon.
