This year, scientists measured more carbon dioxide in the atmosphere than there has been for 800,000 years — since before our species evolved.
Direct observations made on and above Earth’s surface show the planet’s climate is significantly changing. Human activities are the primary driver of those changes.
Earth’s climate has changed throughout history. Just in the last 650,000 years, there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.
Impact of Climate Change on Biodiversity
Biodiversity loss using data on the total number of threatened species of amphibians, birds, fishes, mammals, mollusks, plants, and reptiles. The data were compiled from the Red List published by the International Union for Conservation of Nature (IUCN). For climate change variables, are temperature, precipitation, and the number of natural disaster occurrences. As for the control variable, we have considered governance indicators and the level of economic development. By employing ordinary least square with robust standard error and robust regression (M-estimation), our results suggest that all three climate change variables – temperature, precipitation, and the number of natural disaster occurrences – increase biodiversity loss. Higher economic development also impacted biodiversity loss positively. On the other hand, good governance such as controlling corruption, regulatory quality, and rule of law, reduces biodiversity loss. Thus, practicing good governance, promoting conservation of the environment, and the control of greenhouse gasses would able to mitigate biodiversity loss.

World Snake Day
World Snake Day is July 16. The day is important to the conservation of snakes. Snakes live on every continent except Antarctica and can vary from the longest species, the reticulated python, to the smallest Barbados Threadsnake. Snakes try to avoid human contact. They consider humans predators. Venomous snakes (and many) use their venom to obtain food and only use it for defense when forced to. World Snake Day can help remove people's fears and illusions about snakes, and help them gain recognition as a marvelous adaptable apex species. World Snake Day can be used to educate and inform people about how to deal with snakes. Let's not mis this opportunity.
World Lizard Day
August 14th is World Lizard Day. It's the perfect time to show some love for these remarkable creatures that have been sharing our planet since the time of the dinosaurs. With over 6,000 known species, lizards come in all sorts of shapes, sizes, colors, and patterns, and you can find them on every continent except Antarctica. But why should we celebrate lizards, you ask? Well, they're not just cool to observe in their natural habitats but also essential players in many ecosystems. Lizards help keep insect populations in check, which is vital to our ecosystems. So, let's give these amazing creatures the recognition they deserve on this special day! tems worldwide.
World Turtle Day
Turtles and tortoises have secured their enduring places as enduring symbols in folklore, fables, and popular culture, enchanting our imaginations with their representations of wisdom and resilience. Annually, on May 23, we gather with delight to observe World Turtle Day, a dedicated day that pays homage to these unwavering creatures. Turtles and tortoises, both esteemed members of the reptile family, inhabit an array of diverse environments worldwide, where they play pivotal roles within their ecosystems.
These extraordinary beings don’t merely excavate burrows that become abodes for various other species; they also provide a valuable service by assisting in maintaining the cleanliness of our beaches. Their diet includes the remains of deceased fish that wash ashore, making a substantial contribution to ecological equilibrium. This underscores the profound significance of safeguarding these gentle creatures.
World Turtle Day stands as an occasion specially designated to celebrate and protect both of these remarkable creatures. Its origins can be traced back to 2002 when American Tortoise Rescue introduced this meaningful event. It casts a spotlight on the myriad challenges that turtles and tortoises confront due to human intervention and environmental hazards. On this special day, educational institutions, rescue centers, and nature enthusiasts unite to deepen their understanding of these creatures and pledge unwavering commitments to their preservation.
Here are some impactful ways in which you can actively participate in the endeavor to safeguard these exceptional animals: Adopt a Turtle or Tortoise: Contemplate adopting a turtle or tortoise from a rescue shelter. These low-maintenance creatures make ideal companions, especially for families with young children.
