2338002.cc报道称,一份有关北极地区气候变化影响的报告显示,最近20年,北极地区野生驯鹿数量从将近500万只跌至大约210万只。报道称,一份有关北极地区气候变化影响的报告显示,最近20年,北极地区野生驯鹿数量从将近500万只跌至大约210万只。此外,降雨也是一个重要的问题。北极地区降雨增加,而且常常落在雪地上,在冻原上形成坚固的冰层,动物们无法接触到食物。

据悉,这份报告是在美国地球物理联盟(American Geophysical Research Union)会议上发布的。报告揭露了气候和植被变化为何导致北极苔原地区不再那么适合驯鹿生存的原因。环球变暖对人类将来组成了告急的恐吓。自上世纪70年头往后,环球均匀表面温度不绝在稳定高涨,这敦促环球列国缔结了《巴黎合同》等答应。据悉,该报告由美国国家海洋和大气管理局编撰,该组织已经连续编撰了13年。“如果天气暖和少风,昆虫会感觉闷热,驯鹿要么把昆虫赶走,要么找到一个可以躲避昆虫的地方,会花很多精力。”

环球变暖对人类将来组成了告急的恐吓。自上世纪70年头往后,环球均匀表面温度不绝在稳定高涨,这敦促环球列国缔结了《巴黎合同》等答应。据报道,多个原因导致了这一问题。美国弗吉尼亚大学环境科学家爱泼斯坦(Howard Epstein)表示,北极地区变暖没有减弱的迹象。在全球范围内,要控制这样的情况应减少碳排放,控制气温上升。但是科学家们称,我们已经对“世界冰箱”打开了门。

此外,降雨也是一个重要的问题。北极地区降雨增加,而且常常落在雪地上,在冻原上形成坚固的冰层,动物们无法接触到食物。据悉,这份报告是在美国地球物理联盟(American Geophysical Research Union)会议上发布的。报告揭露了气候和植被变化为何导致北极苔原地区不再那么适合驯鹿生存的原因。此外,降雨也是一个重要的问题。北极地区降雨增加,而且常常落在雪地上,在冻原上形成坚固的冰层,动物们无法接触到食物。

报道称,一份有关北极地区气候变化影响的报告显示,最近20年,北极地区野生驯鹿数量从将近500万只跌至大约210万只。“由于气候变暖,我们看到一些地区干旱现象增加,而变暖本身导致植被发生变化”,他表示,“驯鹿喜欢吃的地衣生长在地面上,气候变暖意味着其他更高的植被要生长,地衣就会被淘汰。”
