Let’s look at our planets climate more closely. Earth has changed a lot throughout our history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.
The planet’s average surface temperature has risen about 2 degrees Fahrenheit (1 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide emissions into the atmosphere and other human activities.Most of the warming occurred in the past 40 years, with the seven most recent years being the warmest. The years 2016 and 2020 are tied for the warmest year on record making it inevitable for us to pay more attention to these changes that are a result of our own human activity.
Looking at the ocean, it was observed that it has absorbed much of this increased heat, with the top 100 meters (about 328 feet) of ocean showing warming of more than 0.6 degrees Fahrenheit (0.33 degrees Celsius) since 1969 and as a result, earth stores 90% of the extra energy in the ocean. But what happens when the ocean can’t store all this energy? This only means that If you are hearing a campaign on stopping these gas emissions, you may now understand why you need to take heed and participate.
