METEO 3 Lesson 10 Images

The image is a graph showing atmospheric carbon dioxide (CO₂) concentrations measured at the Mauna Loa Observatory from 1960 to 2020. The vertical axis represents CO₂ levels in parts per million (ppm), ranging from approximately 320 to 420 ppm, while the horizontal axis displays the years, marked at decade intervals from 1960 through 2020. A red, jagged line illustrates both the seasonal fluctuations and the long‑term upward trend in CO₂ concentrations, with the overall increase highlighted by a black trend line. The graph’s title, “Atmospheric CO₂ at Mauna Loa Observatory,” is displayed at the top. Additional text in the upper left credits the Scripps Institution of Oceanography and NOAA’s Earth System Research Laboratory as the data sources. Two organizational logos appear in the bottom right corner of the image.

The image is a line graph titled “Global Mean Estimates based on Land and Ocean Data.” It presents global temperature anomaly data from 1880 to 2020 along the horizontal axis, while the vertical axis shows temperature anomalies in degrees Celsius, ranging from approximately −0.6 to 1.0. Two lines are displayed: a black line with square markers representing the annual mean temperature anomalies, and a red line indicating the LOWESS‑smoothed trend. The graph reveals an overall upward trend in global temperatures, with particularly sharp increases after the 1980s. Blue error bars appear at several data points, with reduced variability evident in the more recent portion of the record. The data source is credited as NASA GISS in the bottom right corner of the image.

The image is a line graph illustrating global mean temperature anomalies from 1997 to 2014. The horizontal axis represents years, while the vertical axis shows temperature anomalies in degrees Celsius, ranging from −0.1 to 0.8°C. A blue zigzagging line traces fluctuations in temperature anomalies over time. A bold, lighter blue horizontal line runs across the graph between 0.2 and 0.3°C, serving as a reference level. The background features a fine grid pattern to make it easier to read and interpret values. Centered prominently on the graph is blue text stating “No global warming for 18 years 3 months.” Additional annotations indicate a trend value of 0.00°C and r² = 0.000, highlighting the reported lack of a warming trend over the period shown.

The image is a map of the United States displaying average mean temperature trends from 1895 to 2017, shown with a 95% confidence interval. The map uses a color gradient to represent temperature change measured in degrees Fahrenheit per century. Blue shades indicate cooling trends, red shades represent warming trends, and white denotes little to no change.

Most of the map appears in shades of red, indicating an overall increase in mean temperatures over the period analyzed. The darkest red areas are concentrated in the northern and western parts of the country, highlighting regions with the strongest warming trends. A legend at the bottom of the map provides the color scale, ranging from −2.0 to 2.0°F per century, allowing for interpretation of the magnitude of temperature change. The NOAA logo is visible in the southeastern United States portion of the map.

The image is a map of the United States displaying average maximum temperature trends from 1895 to 2017, shown with a 95% confidence interval. Temperature changes are represented using a color gradient measured in degrees Fahrenheit per century, where blue shades indicate cooling trends, red shades represent warming trends, and white denotes little to no change.

Much of the western United States and the Northeast metropolitan region appears in red, indicating an overall increase in maximum temperatures during the period analyzed. The darkest red areas are concentrated in the western portions of the country, highlighting regions with the strongest warming trends. In contrast, parts of the eastern half of the country, including the Mississippi Valley, are shaded in white to blue, suggesting stable to decreasing trends in maximum temperatures.

A legend at the bottom of the map provides the color scale, ranging from −2.0 to 2.0°F per century, allowing for interpretation of the magnitude of temperature change. The NOAA logo is visible in the southeastern United States area of the map.

The animation is a visual representation of Arctic sea ice extent from 1914 to 2013. The ice is depicted as a predominantly white area, surrounded by gradient shades transitioning from light to dark blue, which represent decreasing ice concentration toward the edges. The background is solid black, creating strong contrast that emphasizes the ice coverage. In the top‑left corner, the year is displayed for each frame. As the animation progresses, the white ice area visibly shrinks, allowing viewers to observe the gradual depletion of Arctic sea ice over time.

The animation features two line graphs on a black background, illustrating land ice loss in Antarctica and Greenland from 2002 to 2017. Both graphs display cyan data lines that trend downward, indicating overall ice mass loss over time.

The left graph, labeled “Antarctica” in dark blue at the bottom, shows fluctuating values with an overall declining trend. The series ends in 2017, marked by a magenta dot labeled “2017.”, at approximately −2000 gigatonnes (Gt). The right graph, labeled “Greenland,” shows a steeper and more consistent decline in land ice mass. It also ends in 2017, highlighted by a magenta dot, reaching roughly −4000 gigatonnes (Gt).

Both graphs share the same axis formatting: the vertical axes are labeled in gigatonnes, ranging from 0 to −4000 in 1000‑Gt increments, and the horizontal axes span the years 2002 to 2017. Above both graphs, the title “LAND ICE” appears prominently in white text. Additional text along the bottom provides information about the data source, reference, and graphic creator.

The image is a line graph illustrating sea level change measured in millimeters over the period from 1870 to 1990. The horizontal axis, labeled “YEAR,” spans from 1870 to 1990 and is marked at 20‑year intervals. The vertical axis, labeled “Sea Level Change (mm),” ranges from −50 to 250 millimeters, with tick marks at 50‑millimeter intervals. A blue line represents the sea level data, showing an overall upward trend with noticeable fluctuations, indicating a rise in sea level over time. By 1990, the sea level change reaches approximately 200 millimeters. A horizontal dashed line at the zero mark on the y‑axis indicates the baseline reference level from which changes are measured.

The image is a global map illustrating relative sea level trends, using colorful arrows to represent the direction and magnitude of change. The background shows a world map with continents in green and oceans in blue. Arrows placed across the map indicate sea level trends at various locations: red, yellow, and green arrows represent rising sea levels, while blue, purple, and magenta arrows indicate sinking sea levels, with color intensity reflecting the rate of change.

Across North America and Europe, numerous arrows of varying colors highlight a mix of rising and falling trends. Much of the Pacific Ocean is marked by green and yellow arrows, suggesting predominantly rising sea levels in those regions. Australia and Asia display a combination of colors, showing regional variability but with trends that are mostly increasing overall.

A legend at the bottom explains the arrow colors and directions, as well as the rate of which the sea levels change. 

The image is a map of the contiguous United States showing divisional average temperature ranks for February 2015, relative to historical averages from 1895–2015. The map uses a range of colors to represent temperature conditions compared to the long‑term record.

The western states, including California, Nevada, and Arizona, are shaded in reds, indicating much above‑average to record warmest temperatures. The central United States displays a mix of white and light blue, representing near‑average to below‑average temperatures. In contrast, the eastern states, including parts of Maine, Georgia, and the Carolinas, appear in darker blue shades, indicating much below‑average to record coldest conditions.

Two regions—one near Cleveland and another in central Pennsylvania—are highlighted as experiencing record coldest temperatures relative to the historical average. A legend at the bottom explains the color categories used on the map. The National Climatic Data Center logo appears on the right side, along with the map date of March 4, 2015.

The image is a comparative illustration showing two rectangular containers placed side by side, used to demonstrate the effects of temperature on evaporation and condensation rates. In both containers, a blue liquid layer is visible at the bottom, representing liquid water, while the space above contains small clustered symbols depicting water molecules in the vapor phase.

In the left container, the system is at equilibrium. A blue downward arrow on the left is labeled “Condensation Rate,” and a yellow upward arrow on the right is labeled “Evaporation Rate.” These labels indicate that evaporation and condensation are occurring at equal rates.

The right container shows a similar setup but is placed on a heating element, illustrated as a gray platform beneath the container representing added thermal energy. The same arrows and labels for condensation rate and evaporation rate are present. In this case, the labels indicate that both evaporation and condensation rates have increased due to the higher temperature, while the system remains in dynamic equilibrium.

The image is a weather map depicting rainfall totals across Texas and surrounding states, with a primary focus on Texas. Rainfall amounts are shown using a color‑coded scale measured in inches. The highest totals are concentrated along the Texas Gulf Coast, centered around Houston, and are depicted in bright green to yellow shades, representing rainfall amounts between 30 and 60.58 inches.

Surrounding areas across Texas and into neighboring states display lower rainfall totals shown in lighter colors, including pink, blue, and purple, indicating ranges from 10 to 29.99 inches. The outermost regions are shaded in orange, representing the lowest rainfall amounts of 1 to 9.99 inches.

A black line labeled “Track” marks the path of Hurricane Harvey (2017) across the region. A legend on the right side of the map explains the rainfall color categories. In the bottom‑right corner, a note identifies the maximum recorded rainfall: “Maximum: 60.58 inches, Nederland 1 SW, TX.”
