Global weather patterns are influenced by environmental conditions in places around the world. One of the world’s major weather creators is the Sahara Desert. The Sahara is the largest hot desert in the world. The only larger deserts of any sort are in the polar extremes of the planet and are thus not hot deserts at all.
China and India have 36% of the world’s population and produce about 35% of global CO2 emissions, ranking first and third respectively in that category. The United States, with a little over 4% of the world’s population, produces about 16% of global CO2 emissions, good for second place.
Amphibians are one of the most threatened groups of animals on the planet. Since the late 1980s, scientists have measured dramatic population declines from locations all over the world. The plummeting amphibian populations are perceived to be one of the most critical threats to global biodiversity. According to the IUCN, about 1 of every 3 amphibian species is facing extinction. Some of the greatest threats facing amphibians include climate change, disease, and habitat destruction.
Last year was not the hottest year on record in the United States; it was only the second hottest. 2012 was the hottest because of some searing heat waves that summer. However, 2016 marked 20 above-average temperature years in a row. The five hottest years recorded have all happened since 1998. Every state had a temperature ranking at least in the top seven and both Georgia and Alaska had their hottest years ever. While it was only the second hottest year on record in the U.S., last year was the hottest year for the entire world.
There are many good reasons why we should be making the transition from fossil fuel energy sources but the one that is likely to be the most persuasive is strictly economic. It has long been said that the renewable energy future will truly arrive when installing new solar panels is cheaper than a comparable investment in coal, natural gas, or other options.
We don’t experience climate; we experience weather. And a new study has found that what Americans believe about the changing climate often depends more on their personal experience than what is going on around the world.
Forests are a vital part of biodiversity and are one of the planet’s most important natural repositories for carbon dioxide. They are also continually under attack by multiple forces: more mouths to feed, more wood needed to burn and build with, more paper to manufacture, and more land needed to graze cattle.
The average global temperature is one degree Celsius above pre-industrial levels. There has long been a goal to limit global warming to no more than 2 degrees above those levels. But the Paris climate conference has set a more ambitious goal of limiting global warming to 1.5 degrees. What difference would that half a degree make?
Ecotourism is increasing on a global scale. Ecotourism is generally defined as responsible travel to natural areas that conserves the environment, sustains the well-being of the local people, and involves interpretation and education. Visitor numbers to many protected areas around the world are expanding every year. Ecotourism provides rich experiences for the traveler and often has great benefits to local communities fighting poverty and seeking sustainable development.
