Excessive greenhouse emissions make our planet hotter than ever. Such unprecedented phenomenon is causing a drastic change in the global weather system. In New Zealand, temperature and rainfall changes are already occurring, and more extreme weather events (e.g. drought) are likely to happen.
Carbon dioxide, methane and nitrous oxide are gases that keep our planet warm. Their atmospheric concentrations have increased sharply, though, especially that of carbon dioxide the main greenhouse gas emitted from burning of fuel fossils. Its level has climbed from about 315 parts per million (ppm) in 1958 to more than 375 ppm today, based from researcher Charles Keeling who began measuring CO2 in the Hawaii atmosphere.
The graph was “basically flat until the mid-1800s, then all three move upward in a trend that turns even more sharply upward after 1950,” National Geographic reports in the Big Thaw article. The same is true with CO2 levels in the ocean: it is rising as fast as atmospheric CO2. The Bermuda Monitoring Program also reveals that in the deeper sea levels, the levels are “rising nearly twice the rate as in the surface waters.”
For Bates, it is a sign that something fundamental has changed in this part of the ocean. Climate change advocates, thus, believe that greenhouse gases are climate-change drivers.
Scrap Metal and Recycling
Steel industry emits 3 to 4 percent of the global greenhouse emissions, according to the World Steel Association. Recycling can help reduce carbon emissions in many ways — from saving energy from extraction and manufacturing to saving natural resources — and benefit the environment. Statistically, it can help reduce global fossil fuel emission by 1.8 percent, according to a Reuter report.
Together, you can help scrap metal recyclers like Metal Salvage Services Ltd to reduce carbon footprint via simple ways. Always segregate and know the schedule for metal collection and location of collection centres. Find ways to upcycle and support social enterprises that thrive on upcycling.
These may be little ways, but when done collectively can make a difference. Controlling climate change effects is also our responsibility, after all.
