Global sea level has been rising over the past century, and the rate has increased in recent decades. In 2014, global sea level was 2.6 inches above the 1993 average - the highest annual average in the satellite record (1993-present). Sea level continues to rise at a rate of about one eighth of an inch per year. Higher sea levels mean that deadly and destructive storm surges push farther inland than they once did, which also means more frequent nuisance flooding. Disruptive and expensive, nuisance flooding is estimated to be from 300 percent to 900 percent more frequent within U.S. coastal communities than it was just 50 years ago.
The two major causes of global sea level rise are thermal expansion caused by warming of the ocean since water expands as it warms, and increased melting of land-based ice, such as glaciers and ice sheets. The oceans are absorbing more than 90 percent of the increased atmospheric heat associated with emissions from human activity.
With continued ocean and atmospheric warming, sea levels will likely rise for many centuries at rates higher than that of the current century. In the United States, almost 40 percent of the population lives in relatively high-population- density coastal areas, where sea level plays a role in flooding, shoreline erosion, and hazards from storms. Globally, eight of the world's 10 largest cities are near a coast, according to the U.N. Atlas of the Oceans.
Which of the following could be the main idea of the passage?
B. An increasing rate of sea level rise

DỊCH BÀI:
Mực nước biển toàn cầu đã và đang dâng lên qua thế kỷ trước, và tốc độ đã gia tăng trong những thập kỷ gần đây. Năm 2014, mực nước biển toàn cầu cao hơn 2.6 inch so với trung bình năm 1993 - mức trung bình hàng năm cao nhất trong hồ sơ vệ tinh (1993 - nay). Mực nước biển tiếp tục tăng với tốc độ khoảng 1/8 inch mỗi năm. Mực nước biển cao hơn đồng nghĩa với những cơn bão chết người và có sức hủy diệt sẽ ập vào đất liền sâu hơn so với trước đây, điều này cũng có nghĩa là những trận lũ lụt thiệt hại xảy ra thường xuyên hơn. Những trận lũ lụt tàn khốc và tốn kém ước tính sẽ xảy ra thường xuyên hơn từ 300% đến 900% trong khu vực ven biển Hoa Kỳ so với chỉ hơn 50 năm trước.
Hai nguyên nhân chính gây mực nước biển dâng lên là sự giãn nở nhiệt do nước biển ấm lên vì nước nở ra khi nóng lên, và sự tan băng trên đất liền, chẳng hạn như sông băng và dải băng. Đại dương đang hấp thụ hơn 90% lượng nhiệt gia tăng trong khí quyển liên quan đến khí thải từ hoạt động con người.
Với sự nóng lên liên tục của đại dương và khí quyển, mực nước biển sẽ có thể dâng lên trong nhiều thế kỷ với tốc độ cao hơn trong thế kỷ hiện tại. Ở Hoa Kỳ, gần 40% dân số sống ở các khu vực ven biển có dân cư khá đông đúc, nơi mực nước biển đóng vai trò quan trọng trong việc gây lũ lụt, xói mòn bờ biển và các mối nguy do bão. Trên toàn cầu, 8 trong số 10 thành phố lớn nhất thế giới nằm ở gần bờ biển, theo Atlas of the Ocean từ Liên Hợp Quốc.
