The Climate Crisis




The climate crisis is a long-term change in the average weather patterns that have come to define Earth's local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term. Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around the average conditions (i.e., more or fewer extreme weather events). Climate change is caused by factors that include oceanic processes (such as oceanic circulation), variations in solar radiation received by Earth, plate tectonics and volcanic eruptions, and human-induced alterations of the natural world; these latter effects are currently causing global warming, and "climate change" is often used to describe human-specific impacts.

The impacts of climate change are already being felt around the world, and they are expected to become more severe in the future. These impacts include:

  • Rising sea levels, which are threatening coastal communities around the world.

  • Changes in agricultural yields, which could lead to food shortages.
  • The spread of diseases, such as malaria and dengue fever.
  • The extinction of plant and animal species.

The climate crisis is a serious threat to the planet and its inhabitants. It is important to take action to reduce greenhouse gas emissions and mitigate the effects of climate change.

Egypt Shark Attack.

  A Russian tourist was killed in a shark attack near a beach in the Egyptian Red Sea resort of Hurghada on Thursday, June 8, 2023. The man, who was in his late 20s, was swimming near the Sahl Hasheesh resort when he was attacked by a shark. He was taken to a local hospital, but he died from his injuries. This is the third shark attack in Egypt in the past year. In July 2022, a 68-year-old Austrian woman was killed in a shark attack off the coast of Hurghada, and in October 2022, a Romanian tourist was injured in a shark attack off the coast of Sahl Hasheesh. Shark attacks are rare in the Red Sea, but they do happen. The Red Sea is home to a variety of sharks, including tiger sharks, bull sharks, and mako sharks. These sharks are not typically aggressive towards humans, but they can be if they feel threatened. The Egyptian government has closed off a 60-kilometer (37-mile) stretch of coastline near Hurghada in the wake of the attack. The closure is expected to last for at least a w...

Juneteenth was not officially recognized as a state holiday in Texas until 1979. In 1980, Juneteenth was recognized as a federal holiday in the state of California. In 2020, President Joe Biden signed a bill into law making Juneteenth a federal holiday. Juneteenth is now celebrated in all 50 states. Juneteenth is a time to celebrate the end of slavery in the United States and to reflect on the progress that has been made since then.
