True, environmental challenges have changed significantly since the 1970s.
<h3>What are the changes made to address the environmental issues?</h3>
Environmental issues have become increasingly important in international affairs since 1970.
The initial treaties were the result of regional and national initiatives from a limited number of countries.
However, the topic gained global significance in June 1992, when the United Nations Convention on Climate Change was signed during the Rio de Janeiro Earth Summit.
The Kyoto Protocol, which was signed in Japan in December 1997, extended this accord even further.

Due to lasting resentment of the Versailles Treaty, the National Socialist (Nazi) Party and other radical right-wing parties were able to gain support in the 1920s and early '30s by promising to overturn its harsh provisions and make Germany into a major European power once again.
When President Roosevelt took office March 4, 1933, the nation was confronted by an unparalleled economic and fiscal crisis. To enable the federal government to meet that crisis expeditiously and effectively, the Chief Executive was armed with sweeping emergency powers. Today, five years later, the President retains most of the powers then granted, while others have been extended to him in the intervening period. The authority of the presidential office will be further enhanced, moreover, if Congress enacts this year certain legislation now pending.
