Our Solar System has a star, eight planets, dwarf planets, moons, asteroids and comets.
We call our star the Sun and it includes 99% of all the mass in the Solar System.
The Sun heats and lights our world and allows life on Earth.
It is a luminous object; planets and moons are non-luminous objects but we can see them because of the light they reflect.
The planets orbit the Sun and the Earth is one of the planets.
Moons are large natural satellites that orbit a planet; we have just one moon but some planets have several moons.

Atmospheric carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked for 2021 in May at a monthly average of 419 parts per million (ppm), the highest level since accurate measurements began 63 years ago, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today.
Scripps’ scientist Charles David Keeling initiated on-site measurements of carbon dioxide, or CO2, at NOAA’s weather station on Mauna Loa in 1958. NOAA began measurements in 1974, and the two research institutions have made complementary, independent observations ever since.
In May, NOAA's measurements at the mountaintop observatory averaged 419.13 ppm. Scientists at Scripps calculated a monthly average of 418.92 ppm. The average in May 2020 was 417 ppm.
Pieter Tans, a senior scientist with NOAA’s Global Monitoring Laboratory, noted that CO2 is by far the most abundant human-caused greenhouse gas, and persists in the atmosphere and oceans for thousands of years after it is emitted.
“We are adding roughly 40 billion metric tons of CO2 pollution to the atmosphere per year,” said Tans. “That is a mountain of carbon that we dig up out of the Earth, burn, and release into the atmosphere as CO2 - year after year. If we want to avoid catastrophic climate change, the highest priority must be to reduce CO2 pollution to zero at the earliest possible date.”
CO2 pollution is generated by emissions from carbon-based fossil fuels used for transportation and electrical generation, by cement manufacturing, deforestation, agriculture, and many other practices. Along with other greenhouse gases, CO2 traps outgoing heat from the planet’s surface that would otherwise escape into space, causing the planet’s atmosphere to warm steadily.
While the year-to-year increase of 1.8 ppm in the May CO2 peak was slightly less than previous years, CO2 measurements at Mauna Loa for the first five months of 2021 showed a 2.3 ppm increase over the same five months of 2020, close to the average annual increase from 2010 to 2019. There was no discernible signal in the data from the global economic disruption caused by the coronavirus pandemic.
The highest monthly mean CO2 value of the year occurs in May, just before plants in the northern hemisphere start to remove large amounts of CO2 from the atmosphere during the growing season. In the northern fall, winter, and early spring, plants and soils give off CO2, causing levels to rise through May. Charles David Keeling was the first to observe this seasonal rise and subsequent fall in CO2 levels every year, a dynamic which is now known as the Keeling Curve. Keeling was also the first to recognize that despite the seasonal fluctuation, CO2 levels were rising every year. In fact, every single year since the start of the measurements CO2 was higher than the preceding year.
Keeling’s son, geochemist Ralph Keeling, runs the Scripps program at Mauna Loa.
"The ultimate control knob on atmospheric CO2 is fossil-fuel emissions,” said Ralph Keeling. “But we still have a long way to go to halt the rise, as each year more CO2 piles up in the atmosphere. We ultimately need cuts that are much larger and sustained longer than the COVID-related shutdowns of 2020."
Perched on a barren volcano in the middle of the Pacific Ocean, the Mauna Loa observatory is a benchmark sampling location for CO2. It’s ideally situated for sampling well-mixed air- undisturbed by the influence of local pollution sources or vegetation, producing measurements that represent the average state of the atmosphere in the northern hemisphere.
The Mauna Loa data, together with measurements from sampling stations around the world, are incorporated into NOAA’s Global Greenhouse Gas Reference Network, a foundational research dataset for international climate scientists and a benchmark for policymakers attempting to head off the impacts of climate change.
The atmospheric burden of CO2 is now comparable to where it was during the Pliocene Climatic Optimum, between 4.1 and 4.5 million years ago, when CO2 was close to, or above 400 ppm. During that time, sea level was about 78 feet higher than today, the average temperature was 7 degrees Fahrenheit higher than in pre-industrial times, and studies indicate large forests occupied areas of the Arctic that are now tundra.
In February, the United States officially rejoined the Paris Agreement on climate change, an international treaty signed by 196 countries that have committed to limiting global warming and avoiding its potentially destabilizing impacts.
Yet, as the measurements from Mauna Loa show, despite decades of negotiation, the global community has been unable to meaningfully slow, let alone reverse, annual increases in atmospheric CO2 levels.
“The solution is right before our eyes,”said Tans. “Solar energy and wind are already cheaper than fossil fuels and they work at the scales that are required. If we take real action soon, we might still be able to avoid catastrophic climate change.”

Por nuestros cielos pasan dos vías migratorias europeas, convirtiendo
la península ibérica en un enclave excepcional para observar el
tránsito de las aves. Desde el año 2006, el 2º sábado de mayo y de
octubre se celebra el Día Mundial de las aves migratorias, una ocasión para acercar el mundo de las aves a nuestras aulas.
Las aves, en general y las migratorias en particular, son indicadores de la salud del planeta y del funcionamiento de los ecosistemas.
El cambio climático, la desaparición de los humedales y otras
alteraciones provocadas por la actividad humana como la agricultura
intensiva y la caza ilegal, amenazan la supervivencia de cientos de
especies que cumplen una función reguladora en los ecosistemas.

Los microorganismos son seres que viven en casi todas partes, y son tan pequeños que solo pueden observarse a través del microscopio.
Las
bacterias, virus, hongos, algas y protozoos son microorganismos, en
esta secuencia didáctica se tratarán sus aspectos más importantes,
resaltando tanto sus aspectos beneficiosos como los perjudiciales.
Hacemos clic en la siguiente imagen para ver el mapa conceptual de la secuencia didáctica:
A los microorganismos no los vemos, pero a diario nos aprovechamos de sus beneficios o padecemos sus daños. Más numerosos que todos los demás seres vivos, algunos más antiguos que todos ellos, probablemente seguirán dominando la Tierra mucho después de que los humanos desaparezcan. No solo convivimos con ellos en el planeta, sino que en nuestro propio cuerpo albergamos tantos microorganismos como células humanas.
Reforzaremos la importancia que tienen en nuestras vidas haciendo hincapié en su ubicuidad, en el papel que desempeñan en relación con nuestra salud y nuestras enfermedades y en los procesos biológicos que aprovechamos en nuestra vidas cotidianas. Aprenderemos a conocerlos mejor con ayuda de muestras, uso del microscopio y otros instrumentos propios del laboratorio.
Y si elimináramos una de las enfermedades más antiguas del mundo?
