Global Climate Change

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Radiation: Applications

Radiation: Applications

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

What is Climate?

What is Climate?

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Absorption of Radiation

Absorption of Radiation

The rate of heat transfer by emitted radiation is described by the Stefan-Boltzmann law of radiation:

Microbes and Climate Change

Microbes and Climate Change

Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...

Hess's Law

Hess's Law

There are two ways to determine the amount of heat involved in a chemical change: measure it experimentally, or calculate it from other experimentally determined enthalpy changes. Some reactions are difficult, if not impossible, to investigate and make accurate measurements for experimentally. And even when a reaction is not hard to perform or measure, it is convenient to be able to determine the heat involved in a reaction without having to perform an experiment.

Background:

The net downward radiative flux imbalance (N) at the top of Earth's atmosphere is a key indicator of climate change.
Understanding N variability is crucial for accurate climate change projections.

Purpose of the Study:

To reconstruct and analyze the variability of N using multiple data sources.
To link N variability to recent climate change and major climate phenomena.

Main Methods:

Combined satellite data, atmospheric reanalyses, and climate model simulations.
Reconstructed N variability over the 1985-2012 period.
Analyzed interannual variability influenced by volcanic eruptions and ENSO.

Main Results:

Mean N was higher in 2000-2012 (0.62 ± 0.43 Wm⁻²) compared to 1985-1999 (0.34 ± 0.67 Wm⁻²).
N variability showed significant correlation (r~0.6) between climate model ensembles and satellite-based reconstruction.
Interannual variability was dominated by the 1991 Mount Pinatubo eruption and ENSO events.

Conclusions:

Despite uncertainties in N's precise magnitude, the reconstruction captures significant interannual climate variability.
The study highlights the influence of major events on Earth's energy imbalance.
Findings provide valuable insights for refining climate models and understanding climate dynamics.
