Global warming has had significant effects in recent decades. Rising temperatures have caused glaciers and sea ice to melt and increased the frequency of extreme weather events. Ocean acidification from higher CO2 levels bleaches coral reefs and disrupts marine habitats. As the climate changes, human health is also threatened by worsening air pollution and increased exposure to UV rays. If emissions continue unchecked, climate change poses a severe risk to both the environment and human societies.

1. Global warming is one of the most pressing issues facing our planet today. It has been a major
concern for many years, but in the past 10 years, its effects have become more evident. The
consequences of global warming are far-reaching and can be seen all over the world in various
forms. In this essay, we will explore some of these effects that have been observed over the last
decade.
The first effect to consider is rising temperatures across much of the globe due to increased
levels of carbon dioxide trapping heat from sunlight within our atmosphere. This has caused an
increase in the average temperature of around 1 degree Celsius since preindustrial times, which
may not seem like much but is enough to cause noticeable changes such as melting glaciers and
sea ice at higher latitudes or longer droughts further south, causing loss of vegetation cover and
leading to the desertification process. Additionally, extreme weather events like hurricanes and
floods are becoming increasingly common due to warmer air storing more energy, making
storms stronger than ever before.
Another effect of global warming is ocean acidification, which occurs when increased CO2
concentrations in the oceans cause a decrease in pH levels and the bleaching of coral reefs,
making them vulnerable to disease outbreaks and eventually killing them. Furthermore, ocean
currents affected by thermal expansion also disrupt marine life’s natural habitat, thus decreasing
biodiversity even further. Finally, human health concerns arise when polluted air becomes
trapped near ground level as a result of smog produced by the combustion of fossil fuels,
increasing respiratory diseases among the population, particularly children, who suffer the most
from asthma attacks during the summer months when the ozone layer weakens further, allowing
UV rays to penetrate through the atmosphere directly on the earth's surface, damaging skin cells
along the way.
To summarize, global warming has had a dramatic impact on both the environment and human
societies over the last decade, ranging from rising temperatures to ocean acidification, which has
threatened entire ecosystems, including us humans who live here! We must act now before it gets
any worse by reducing emissions and switching to renewable energy production if we want
future generations to live healthy lives without worrying about climate change every single day!
