The Effects of Global Climate Change: Home

Some of the long-term effects of global climate change in the United States are as follows, according to the Third and Fourth National Climate Assessment Reports.

The Earth's temperature had already warmed by 1°C compared to pre-industrial levels. This temperature rise may appear small, but small rises in temperature translate into big changes for the world’s climate.

Climate change, whatever the cause, has profoundly affected human societies and the natural environment in the past.

A changing climate means changing habitats, threatening vulnerable species.

Why thawing permafrost matters

The changing climate is having far reaching impacts on agricultural production, which are likely to challenge food security in the future.

Kiribati is one of the most isolated countries in the world. As you fly in to the main island of South Tarawa, located less than 100 kms from the equator, a precariously thin strip of sand and green materialises out of the ocean.

Agriculture is strongly influenced by weather and climate and in turn influences climate through greenhouse emissions and land clearance

Bushfire conditions are now more dangerous than in the past, and the risk to people and property has increased. For well over 20 years, scientists have warned that climate change would increase the risk of extreme bushfires in Australia. This warning was accurate.
