Global warming is the rising average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's average surface temperature has increased by about 0.8 °C, with about two thirds of the increase occurring since 1980. Warming of the climate system is unequivocal, and scientists are more than 90% certain that most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels.

Đọc đoạn văn sau và trả lời các câu hỏi: Since the world has become industrialized, there has been an increase in the number of animal species that have either become extinct or have neared extinction. Bengal tigers, for instance, which once roamed the jungles in vast numbers, now number only about 2,300, and by 5 the year 2025 their population is estimated to be down to zero. What is alarming about the case of the Bengal tiger is that this extinction will have been caused almost entirely by poachers who, according to some sources, are not interested in material...
The Lost World is a novel released in 1912 by Sir Arthur Conan Doyle concerning an expedition to a plateau in the Amazon basin of South America where prehistoric animals (dinosaurs and other extinct creatures) still survive. It was originally published serially in the popular Strand Magazine during the months of April 1912-November 1912. The character of Professor Challenger was introduced in this book. The novel also describes a war between Native Americans and a vicious tribe of ape-like creatures....
Life on Earth originated and then evolved from a universal common ancestor approximately 3.7 billion years ago. Repeated speciation and the divergence of life can be inferred from shared sets of biochemical and morphological traits, or by shared DNA sequences. These homologous traits and sequences are more similar among species that share a more recent common ancestor, and can be used to reconstruct evolutionary histories, using both existing species and the fossil record. Existing patterns of biodiversity have been shaped both by speciation and by extinction....
The relationship between the manufacturers of electronic components and the
assemblers of electronic circuitry resembles that between two different orders of
living beings, for example insects and plants: they need one another to be able to
exist, and for that reason there are close links between the evolutionary paths of
both. The shapes and the dimensions of their bodies, or respectively their functions,
must match one another, so that whatever is needed to ensure the survival of either
species can be properly performed. Any mistakes or mismatches are punished by
Information about climate1 is used to make decisions every day. From farmers deciding
which crops to plant next season to mayors in large cities deciding how to prepare for future heat
waves, and from an insurance company assessing future flood risks to a national security planner
assessing future conflict risks from the impacts of drought, users of climate information span a
vast array of sectors in both the public and private spheres. Each of these communities has
different needs for climate data, with different time horizons (see Box 1) and different tolerances
Human activities are affecting the global environment in myriad
ways, with numerous direct and indirect effects on ecosystems.
The climate and atmospheric composition of Earth are changing
rapidly. Humans have directly modified half of the ice-free terrestrial
surface and use 40% of terrestrial production. Our actions are
causing the sixth major extinction event in the history of life on
Earth and are radically modifying the interactions among forests,
fields, streams, and oceans.
