According to the data from a satellite that was launched to measure the thickness of the polar caps the sea ice in the Arctic is disappearing at a greater rate than that of the one that was previously expected. the rate of loss is about 50 percent higher than most of the scenarios that were outlined by scientists, this suggests that global warming triggered by greenhouse gasses is starting to have a major impact on the region. In some places like Greenland where the ice thickness used to be about five to six meters now in the summer it is down to about one to three meters. If the ice continues to melt like this in the summer time then ocean temperatures could rise, and methane deposits on the ocean floor could melt. when winter starts ice starts to grow back more rapidly than it did in the past so it is almost compensating for the loss in the summer time.
We need to do something about the global warming effect. If we keep contributing to all of these greenhouse gasses, and making global warming happen, then the ice will continue to melt at a very high rate. This would kill fish, and hurt the ecosystem. There are somethings that hold us back from stopping global warming such as, that people don't believe in it. My opinion is that we need to stop contributing to global warming because I want this planet to still be here for years on end, and for many further generations to come.

You are right. Global warming is a big problem and people aren't concerned enough about it. You are right too that one of the big problems is people don't "believe" in it. Global climate change is very real, and we need to do something about it. The public needs to be more aware.
