Global warming occurs naturally but is now exacerbated by human activities like industrialization. The greenhouse effect involves gases in the atmosphere trapping heat from the sun, warming the planet. Increased greenhouse gases from human activities have raised the Earth's surface temperature to new highs and caused severe weather events. If emissions are not reduced, scientists warn of even greater temperature rises, more extreme storms, floods and droughts, and small island nations being submerged due to sea level rise from melting ice sheets and thermal expansion of oceans. International agreements like the Kyoto Protocol have aimed to reduce emissions but more action is still needed to prevent destructive climate change impacts.
a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
Global warming is causing average temperatures to rise due to increased greenhouse gases trapping heat in the atmosphere. This is resulting in sea level rise, more extreme weather, and impacts to ecosystems. Key effects include melting glaciers and ice sheets, rising sea levels, stronger hurricanes, ocean acidification harming coral reefs, and changes to forest and plant life. While some effects like increased rainfall in some areas may have benefits, on the whole the impacts of climate change are expected to be severely damaging to human and natural systems.
Global warming refers to the average increase in Earth's temperature caused by both natural and man-made factors such as greenhouse gas emissions. The document discusses the causes and effects of global warming as well as resolutions like the Kyoto Protocol, which aims to reduce greenhouse gas emissions, and individual actions that can be taken to address the issue.
This document discusses global warming and its causes and effects. It begins by defining global warming as the rising of Earth's temperatures due to more heat being trapped near the surface. It then explains the greenhouse effect, where gases like carbon dioxide and methane absorb and emit infrared radiation, trapping heat. The document lists several human causes of increased greenhouse gases, such as the burning of fossil fuels for energy and transportation. It also discusses how deforestation reduces carbon dioxide absorption. The effects of global warming mentioned include melting glaciers, rising sea levels which can flood low-lying areas, more wildfires, and destruction of forests due to acid rain. The document concludes by suggesting some precautions like using renewable energy, driving efficient vehicles, planting
The document discusses greenhouse gases and their role in the greenhouse effect. It notes that 31% of incoming solar radiation is reflected by clouds, atmosphere and land, while 30% is absorbed by the atmosphere. The remaining radiation warms Earth's surface. Increased greenhouse gas concentrations mean less heat is released to space, increasing average surface temperatures. Tree ring data provides long-term climate records, with thicker rings indicating optimal growth conditions.
Water vapor, carbon dioxide, and methane are greenhouse gases that absorb infrared radiation emitted from the Earth's surface and atmosphere. While water vapor accounts for the largest percentage of infrared absorption, rising levels of carbon dioxide and methane from human activities like burning fossil fuels are contributing most to increased global temperatures. The speed of current climate change caused by greenhouse gas emissions is unprecedented and poses serious risks to ecosystems if average temperatures rise more than 3 degrees Celsius.
The document discusses global warming and its causes and effects. It notes that global warming is caused by increased greenhouse gases from human activities like burning fossil fuels and deforestation. This has led to rising global temperatures and more extreme weather. Effects include habitat destruction, species extinction, and adverse impacts on human health, water resources, and coastal populations. Reducing greenhouse gas emissions, switching to renewable energy, and increasing forests are recommended to mitigate global warming. Individual actions like reducing consumption and spreading awareness can also help address the problem.

This document discusses climate classification systems and the factors that cause climate change. It begins with an overview of weather versus climate and the Koppen climate classification system. The major climate types are then described in detail, including tropical, dry, mild, continental, and polar climates. Various natural and human factors that can disrupt climate patterns are outlined, such as solar activity, volcanic eruptions, greenhouse gases, and deforestation. Evidence of past climate changes is examined through paleoclimate research techniques. Feedback mechanisms are described that can amplify the impacts of initial changes.
The water cycle describes the continuous movement of water on, above, and below the Earth's surface, driven by energy from the sun. Through evaporation, water is lifted into the atmosphere where it cools and condenses to form clouds. Water then falls back to Earth as precipitation through rain or snow and collects in rivers, streams, and oceans or is absorbed into the ground as groundwater, completing the cycle. The water cycle is crucial for sustaining life.

1. The document proposes a 5-day lesson plan using quadratic functions to teach students about climate change and environmental protection.
2. On day 1, students learn about climate change by watching a documentary and singing a song. On day 2, they discuss how humans affect global warming.
3. On days 3-4, students analyze quadratic functions in vertex form and how reforesting mountains can stabilize landslides and floods. They propose functions to model reforestation efforts.
4. On day 5, students participate in a tree planting activity to help reduce greenhouse gases by absorbing carbon dioxide.
Population growth and increases in carbon dioxide emissions both rose significantly from 1980 to 2009. While a positive correlation exists between the two, statistical analysis shows the relationship is weak. The chi-square test results fail to reject the null hypothesis that population growth and carbon emissions are independent. Therefore, while human activities like energy use that produce carbon emissions rise with growing populations, population growth alone does not sufficiently explain increasing carbon dioxide levels according to this analysis. Other factors must also influence annual carbon emission amounts.
This document describes a student's work on an internal assessment for an IB math class involving finding patterns in Lacsap's Fractions, a triangle of fractions similar to Pascal's triangle. The student finds equations to predict the numerator and denominator of any element in the triangle. For the numerator, the student derives the equation N=R(R+1)/2, where N is the numerator and R is the row number. For the denominator, the student derives the equation D=(R-E)2-R, where D is the denominator, R is the row number, and E is the element number. Using these equations, the student can determine any element in Lacsap's Fractions.
Climate change is a serious problem that can be understood through simple math. Burning fossil fuels is releasing carbon dioxide that is trapping heat in the atmosphere and changing the climate in dangerous ways. If we want to avoid catastrophic consequences, we must transition to renewable energy sources and leave fossil fuels in the ground.
The document summarizes a study that investigated the relationship between height and shoe size in 20 women and 20 men. It found a weak positive correlation, such that taller individuals tended to have larger shoe sizes. However, the relationship varied substantially between individuals. A chi-square test found no definitive relationship, though the idea that taller people generally need larger shoes to maintain balance was supported. Limitations included potential inaccuracies in self-reported height and shoe size data.

The document analyzes the relationship between SAT scores and family income of test takers worldwide based on data from the College Board in 2007. The author conducts a mathematical investigation including generating scatter plots, calculating the least squares regression line and correlation coefficient, and performing a chi-squared test. The results show a strong positive linear correlation between SAT scores and family income, indicating family income has a significant impact on SAT scores. However, the study has limitations as it only includes those who reported income and may not capture all SAT test takers.
The document discusses the major causes and effects of climate change. The main causes are natural factors like changes in Earth's orbit and methane release from tundra, as well as human factors such as burning fossil fuels, deforestation, industrial pollution, and increased population. Some effects of rising temperatures include melting ice and glaciers, rising sea levels, more extreme weather, and disrupted animal habitats. The document also briefly mentions alternative energy sources and individual actions people can take to help address climate change.
This document defines climate change as a change directly or indirectly caused by human activity that alters the composition of the atmosphere in addition to natural variability. It lists both natural causes like volcanic eruptions and human causes such as greenhouse gas emissions, deforestation, and burning fossil fuels as contributing to climate change. The effects of climate change discussed include rising sea levels from melting ice sheets, more extreme weather events like heavy rainfall and drought, declining crop productivity, changing ecosystems, rising temperatures, and ocean acidification.
This document discusses climate change and provides information about the difference between weather and climate. It explains that climate is affected by both abiotic and biotic factors. Greenhouse gases are essential to our climate by trapping heat in our atmosphere. However, human activity has increased greenhouse gas levels, resulting in global warming. Evidence of climate change comes from melting glaciers, tree rings, and changes in plant and animal ranges. The document suggests various ways individuals can reduce their carbon footprint through conserving energy use at home, in transportation, and reducing waste.

Graphs, Edges & Nodes - Untangling the Social WebJoël Perras
Many of the most popular web applications today deal with highly organized and structured data that represent entities, and the relationships between these entities. LinkedIn can tell you how many degrees of separation there are between yourself and the CEO of Samsung, Facebook can figure out people that you might already know, Digg can recommend article submissions that you might like, and LastFM suggests music based on your current listening habits.
We’ll take a look at the basic theory behind how some of these features can be implemented (no computer science degree required!), and then dig in to a few practical implementations using PHP & and a relational database, as well as with Redis. Lastly, we’ll take a quick look at the current landscape of graph-based datastores that simplify many of these operations.

This document contains a worksheet with 6 problems involving similar triangles. The first problem contains two similar triangles with missing side lengths x and y. The second problem asks the reader to find x if two specified triangles are similar. The third and fourth problems involve setting up and solving proportions between corresponding sides of similar triangles. The fifth problem contains a "tricky" proportion involving addition. The sixth problem uses similar triangles formed by a pole, man, and their shadows to find the height of the pole.
The document is about graphing lines stations for a math class. It includes instructions and examples for 4 stations where students graph lines from given equations and write the equation of a line from its graph. The stations provide practice identifying the equations of lines from graphs and plotting lines on graph paper from equations. There is also an activity where students create and trade linear equations to graph each other's lines.
This document discusses proportional segments in triangles. It states that the segment connecting the midpoints of two sides of a triangle is half the length of the third side. It also states that if two triangles are similar, then their altitudes and medians will be proportional. Finally, it discusses that if an altitude is drawn from the right angle of a right triangle to the hypotenuse, the two new triangles formed will be similar to the original triangle and to each other.
This document discusses cooperative or co-teaching between two teachers in a classroom. It states that for co-teaching to be successful, the teachers must (1) share a common goal for student success, (2) have a strong personal belief in the co-teaching model, and (3) respect each other and their different strengths. It also identifies key factors for effective co-teaching such as planning time, shared philosophies, and evaluating student outcomes. Barriers like lack of time, uncoordinated grading, and teacher/student readiness must also be addressed.
This document discusses analyzing test items to determine their difficulty and ability to differentiate between high and low scoring examinees. It provides guidelines for interpreting facility and discrimination indices. The facility index represents the percentage of examinees answering an item correctly, and discrimination is a number indicating how well an item distinguishes high and low performers. Examples are given of calculating these indices and analyzing item performance based on the results.
