The document discusses climate zones and climate change. It defines climate and describes Canada's seven climate zones which are determined by factors like proximity to bodies of water, altitude, and latitude. Climate change is causing more extreme weather and temperature increases in some regions. The main causes of climate change are greenhouse gas concentrations and changes in factors like solar radiation and the Earth's orbit. Climate change can have both pros, like longer growing seasons, and cons, like damage to plants from higher temperatures and melting of polar ice caps.

Global Warming
The document discusses global warming, its causes, and potential consequences. It notes that the past few decades have been the hottest on record and that climate change denials have been disproven. The main cause of global warming is carbon dioxide and other greenhouse gas emissions trapping heat in the atmosphere. Burning fossil fuels for electricity and transportation are the primary sources of these emissions in the US. Consequences of continued warming may include more severe droughts and wildfires, rising sea levels, damage to agriculture and fisheries from heat waves and pests, and species extinction. Reducing emissions from activities like deforestation and transitioning to cleaner energy are necessary to address global warming.
AP Environmental Science Ch. 19, part 1 Miller LITE
This document discusses evidence of climate change from various scientific sources. It notes that temperatures are rising globally, with the hottest years on record occurring recently. Various indicators are changing as well, such as glacial melting, sea ice shrinkage, and sea level rise. The evidence demonstrates that climate change poses serious risks and is largely due to human activities like burning fossil fuels. Understanding changes in the climate over past centuries and millennia relies on scientific data from sources like ice cores, tree rings, and ocean sediments.
Global warming
Scientists have determined that global warming is caused primarily by human-produced greenhouse gas emissions from activities like burning fossil fuels. The main greenhouse gases are carbon dioxide, methane, and nitrous oxide, which are emitted through activities like driving, electricity production, agriculture, and industrial processes. While natural factors also influence the climate, the current rapid warming trend cannot be explained without accounting for human greenhouse gas emissions. Global effects are already appearing, such as rising temperatures, melting ice sheets and glaciers, sea level rise, and shifts in animal and plant ranges.
Global Warming
The document discusses how the atmosphere is the most vulnerable part of the ecological system due to its thin composition that can be changed by human activity. It explains the greenhouse effect and how increased levels of carbon dioxide and other gases trap more infrared radiation, heating the atmosphere and leading to global warming. Roger Revelle was among the first to measure rising carbon dioxide levels in the atmosphere and observe annual fluctuations linked to plant respiration in the northern and southern hemispheres. Carbon dioxide levels have risen over 40% since 1000 AD and global temperatures have increased over 80%, beyond natural levels over the past 650,000 years. Effects of global warming include stronger storms, floods, droughts, and earthquakes.
AP Environmental Science Ch. 19, part 2
Potential and realized consequences of climate change include:
1) Drought, melting ice, rising sea levels, and permafrost melt are already occurring as a result of climate change.
2) Additional potential consequences that some experts say may already be happening include altered ocean circulation patterns and more extreme weather events.
3) Further potential consequences include threats to biodiversity like coral bleaching and disrupted animal migration patterns, shifting agricultural production, and risks to human health from factors like heat waves.
Global warming
The document discusses the scientific consensus on the causes and effects of global warming. It explains that scientists have concluded human greenhouse gas emissions are the main cause of current global warming trends, based on extensive research ruling out natural factors alone. The document outlines some of the major greenhouse gases emitted by human activities that are contributing to increased temperatures worldwide, and provides examples of impacts already occurring like glacial melting as well as potential future impacts if warming continues such as rising sea levels.
Abioitc biotic
An ecosystem is a region containing living and non-living components that interact. Non-living abiotic factors like elevation, nutrients, and temperature influence living biotic factors like plants and animals. In Colorado, ecosystems or biomes change with elevation from plains to foothills to montane to subalpine to alpine life zones, with abiotic factors like temperature decreasing and rainfall/snow increasing with higher elevations. Ecological changes with elevation are similar to changes with increasing latitude.

Climate change
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.
Climate Change & Causes
Climate change occurs over short, medium, and long timescales. Short-term climate change involves global warming over decades, while medium-term changes occurred over thousands of years according to ice core and fossil records. Long-term changes shaped climate over hundreds of thousands to millions of years. Recent climate change has led to 0.5°C warming globally since 1970 due to increased greenhouse gas emissions from human activities like burning fossil fuels. This enhanced greenhouse effect from carbon dioxide and methane emissions is trapping more heat in the atmosphere and causing unprecedented global warming according to temperature and Arctic sea ice records.
Climate changes past and future
- Climate change occurs on various timescales and is influenced by factors like solar activity, Earth's orbit, atmospheric composition and greenhouse gases, volcanic eruptions, and human activities like fossil fuel burning.
- Evidence from geology and fossils shows past climate changes, including intervals warmer than today and ice ages. The last ice age peaked around 20,000 years ago and glaciers have since retreated.
- Future climate is uncertain but computer models predict global warming and changing precipitation patterns if CO2 doubles from current levels due to feedbacks like ice-albedo and water vapor effects. Careful study of past and present helps understand complex climate system.
Earth's Climate
The document discusses several factors that influence Earth's climate:
1) Solar energy is the main driver of climate, affecting global temperatures as it is absorbed by the atmosphere, oceans, and land.
2) Other factors like Earth's orbit, axial tilt, and rotation influence the distribution of solar radiation and cause seasonal changes.
3) Large bodies of water like oceans influence climate by slowly storing and transferring heat around the world.
Edited 350
This document discusses the science behind climate change and its impacts such as rising sea levels, melting glaciers, more extreme weather, and threats to food production. It argues that CO2 levels need to be reduced from 387 parts per million to 350 ppm or lower to stabilize the climate. However, global emissions continue to rise and are accelerating climate change far faster than predicted. The document calls for a global movement to demand real action from policymakers, including transitioning away from fossil fuels to renewable energy and implementing other solutions, to reduce emissions 80% by 2050 and keep global temperature increase below dangerous levels.
Global Warming
Global warming is being caused by human activities that release heat-trapping gases into the atmosphere. This is trapping heat and changing the climate faster than some living things can adapt to, causing glaciers and ice sheets to melt and sea levels to rise. If unchecked, global warming will lead to more extreme weather events like major storms, floods, and droughts, and will impact plants and animals. Collective action is needed to reduce the use of polluting activities, conserve energy, and adopt more environmentally-friendly practices to mitigate the effects of climate change.
Climate change global warming.
Global warming refers to rising average temperatures around the world since 1880 due to increased carbon dioxide in the atmosphere from human activity like burning fossil fuels. The effects of warming are already apparent through melting Arctic ice, glaciers and snow, and temperatures are rising faster in the Arctic. If unchecked, global warming could lead to problems like severe food and water shortages, a rise in sea levels of 7 to 23 inches by 2100, and over a million species facing extinction due to habitat loss and changing ecosystems.
Unit 5 b ch 13 s1 climate & climate change
Weather is the short-term atmospheric conditions while climate is the long-term prevailing weather patterns of an area. The four main factors that determine climate are latitude, atmospheric circulation patterns, oceanic circulation patterns, and local geography. Latitude determines the amount of sunlight an area receives, which impacts temperatures and seasonal variations. Atmospheric circulation patterns such as global wind belts and ocean currents redistribute heat around the Earth, influencing coastal and regional climates. Seasonal changes are caused by the tilt of the Earth's axis, which alters the angle at which sunlight strikes different parts of the planet throughout the year.
Long term & short term effects of climate 2
The document discusses long and short term changes in climate. Long term changes occurring over millions of years are influenced by continental drift and changes in Earth's orbit. Short term changes occurring over decades to thousands of years can be caused by volcanic eruptions, fluctuations in the sun's radiation, and shifts in ocean and air currents. Major long term climate shifts are also linked to variations in Earth's axial tilt, orbital shape, and the wobbling direction of its axis.
Thomas Lovejoy, WILD9
The document discusses the impacts of climate change on various species and ecosystems. It notes that species ranges and nesting times have shifted, some species have gone extinct, and ecosystems are disassembling and reassembling into new configurations. It also discusses the need to limit greenhouse gas concentrations to 350ppm through measures like revising energy systems, reducing deforestation, and restoring ecosystems to facilitate species movement under climate change.

Climate change part 1
The document discusses evidence that the world is getting warmer based on various temperature records and proxy climate data:
- Instrumental records show global surface temperatures have risen 0.6°C over the past 50 years and the past few decades have been the hottest on record.
- Proxy climate data from tree rings, ice cores, corals, lake sediments, and ocean sediments extending thousands of years indicate the current warming trend is unprecedented over the last 2,000 years based on northern hemisphere temperature reconstructions.
- While some periods in the past like the Medieval Warm Period were warmer than today in some regions, the global temperature rise of the last century stands out when considering records from across the globe.

Long and Short Term Changes of Climate discusses various factors that cause changes in climate over both small and long terms. Small-term changes are caused by volcanic eruptions, small variations in solar radiation, and shifts in air and ocean currents. Long-term changes are influenced by changes in Earth's energy balance, orbital variations, glacial activity, plate tectonics, and human influences like fossil fuel usage. The document also discusses how climate change can affect animals and ecosystems, as well as how scientists monitor and study climate change.
Climate System
The document discusses the Earth's climate system and factors that can cause climate change. It defines climate as the long-term atmospheric conditions of an area, whereas weather refers to short-term conditions. Climate change occurs when factors like greenhouse gases, solar variability, volcanic eruptions, and human activities disrupt the global energy balance. The climate system includes interactions between the atmosphere, oceans, ice sheets, and land that influence heat distribution.
Climate Change Past Present Future
This document summarizes information about past, present, and projected future climate change from various scientific studies. It discusses how paleoclimatology uses natural proxy records like tree rings, ice cores, and pollen to estimate past temperatures back to years before instrumental records. Instrumental records from 1850 onward show global warming of 0.8°C since that time. Proxy records also indicate similar warming of 1.1°C since the 1700s. Future projections from the IPCC estimate further warming this century depending on scenarios for greenhouse gas emissions, with increases ranging from just over 1°C to almost 4°C.
Global warming

Weather.climate edited
Weather refers to short-term atmospheric conditions in a small area that can change rapidly, while climate describes long-term patterns over 100+ years in a large area that changes very slowly. Seasons are caused by the tilt of the Earth's axis of rotation relative to its orbit around the sun, which determines how direct sunlight strikes each hemisphere over the course of a year. The summer solstice marks the longest day of the year when the sun's rays are most direct, while the winter solstice is the shortest day with the most indirect sunlight.

Climate is determined by temperature and precipitation, which are affected by various natural factors. Latitude affects temperature, with warmer temperatures closer to the equator and colder temperatures farther from the equator. Elevation also impacts temperature, with higher elevations experiencing cooler temperatures due to less dense air. Ocean currents influence nearby land temperatures, with warm or cold currents causing temperature variations. Precipitation is impacted by prevailing winds and mountain ranges, with windward sides of mountains receiving more rain and leeward sides receiving less. The world's climates can be divided into polar, temperate, and tropical zones based on average temperatures.
4202: Climate change-1
This document provides information on climate change from a lecture given by Md. Abdullah-Al-Mahbub. It defines weather and climate, noting that weather is specific conditions over days while climate is average conditions over decades for a region. It discusses factors that determine climate like latitude, altitude, winds, and oceans. It also covers causes of climate change, distinguishing between natural causes like orbital changes, solar variations, and volcanic eruptions, and anthropogenic causes like greenhouse gas emissions from fossil fuel use and population growth since the Industrial Revolution. Finally, it lists some critical changes caused by climate change like warming temperatures, changes to the water cycle, and declining glaciers.
Climate zones and climate changes (2)
This document discusses climate zones and climate change. It begins with an introduction to climate and what determines climate zones.

Climate Change
Climate change refers to long-term shifts in weather patterns due to human activities like burning fossil fuels and deforestation that release greenhouse gases. This leads to an average rise in global temperatures, causing effects like sea level rise that threaten coastal regions and glacial melting that endangers wildlife. While some climate change occurs naturally from phenomena like volcanic eruptions, human activities are the main driver of currently observed changes like increased droughts and extreme weather events. Reducing greenhouse gas emissions through measures like improving fuel efficiency, expanding renewable energy, and increasing carbon sequestration can help mitigate further climate change impacts.
Sec 2 NA Gobal Warming
Global warming is caused by an increase in greenhouse gases like carbon dioxide and methane trapping more heat from the sun. This enhanced greenhouse effect leads to consequences like changes in weather patterns, rising sea levels, and impacts on plants, animals, and humans. Higher temperatures can spread diseases and damage crops and habitats. Melting ice caps cause sea level rise which destroys land and forces people to relocate from coastal areas. Solutions are needed to address the problems from climate change.

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
