The need for reliable information online about our climate is more apparent than ever. Which is why Wikimedia UK launched our first climate-focused residency in partnership with GSI at the University of Exeter. Tatjana will work alongside several world-leading climate scientists, including those at the UK Met Office. We’re delighted to welcome Tatjana to our team, and hope everyone in the editing community will give her a warm welcome.
By Tatjana Baleta, Wikimedia Visiting Fellow at Global Systems Institute, University of Exeter
I am a South African conservationist and science communicator with an interest in the power of knowledge to drive change. As the Wikimedia Visiting Fellow at the GSI, I will be working with researchers and the Wikimedia community to make climate change knowledge more accessible, expand and strengthen the quality of climate change information available on open knowledge platforms and to combat dis- and misinformation.
My fascination with the natural world led me pursue a BSc in Ecology & Evolution and Genetics and a BMedSc(Hons) in Cell Biology. With a growing understanding of the global environmental crisis, I then completed an MPhil in Conservation Leadership.
I have worked internationally in research and communications on marine species monitoring, marine litter monitoring, marine protected area design research, conservation technology, species prioritisation and conservation-decision making.
As an avid science communicator, I am passionate about sharing my love for the natural world, and particularly about using that communication to instigate positive change.
I’m really excited to dive into this opportunity to explore open knowledge systems and contribute to climate change resource accessibility.

To Tatjana Baleta:Solar panels are not clean energy, it will accelerate global warming!
For the recent warming of the global climate acceleration,disasters in various places and a large number of extreme situations,many scholars are still completely unable to solve the state!Watch the construction wave of speculators over the myth of solar panel hype,but they don’t know the current situation of the earth’s real environment,based on the situation I have observed, where is the current out-of-control point in the world?
Many people think solar panels are like photosynthesis,but in fact, solar panels do not absorb heat,so solar panels cannot replace plants in the natural world!before all chemical reactions,need to be supplied with energy from the outside,called “endothermic reaction”.
For example, when plants convert carbon dioxide and water into sugar,it needs solar heat,carbon dioxide and water cannot synthesize sugar without solar heat,so photosynthesis is an endothermic reaction,but solar panels are different.A solar panel is a power generating device that generates direct current electricity when exposed to sunlight,all combined with semiconductor materials,the solar panel system will simply absorb solar photons to generate electricity,but does not absorb heat,so any solar panel needs a cooling device.
The sunlight emitted by the sun from its own star contains the energy and thermal energy of solar photons,photons are wave-particle duality,it’s energy but it’s also particles,heat is pure energy,so solar photons can carry heat energy to the earth together.Ok,first let’s review,what is the photoelectric effect of solar panels!Einstein advocated,the energy of light is not evenly distributed,It is loaded on discrete photons,if an electron in a solar panel absorbs the energy of a photon,this energy is greater than or equal to some energy value associated with the metal of the solar panel,we call it the work function of the metal,because this electron has enough energy, it will escape from the metal of the solar panel,become a photoelectron, the photoelectric effect you learned about in school.
Then it was said that the solar panel only absorbs the energy of photons, but does not absorb heat energy,so imagine when the sun’s light, led by photons, reaches the earth,according to theory, 30% of sunlight will be reflected from the earth back to space under the guidance of photons,but when the photons of sunlight are absorbed, where does the remaining 30% of the thermal energy go?
In various chemical reactions, no loss of mass of matter occurs; in all physical changes, there is no loss of energy. — Sir Henry Enfield Rothko.
The above passage is a basic iron law in our universe: the law of conservation of energy.Energy does not come into being for no reason, nor does it disappear out of thin air, it must be transformed from one form to another.In the dependent mode, energy can only move and do work on mass,if there is no medium carrier for all energy in the process of movement, the energy will not be transferred.So when the solar photons are absorbed by the solar panel, the heat energy will not disappear, and the only place it can go is the atmosphere!
During the long years of the earth’s existence, the sun’s thermal energy will reach the earth under the leadership of photons,about 30% of the solar energy will be reflected back to space under the guidance of photons, and the rest of the solar energy will be mostly absorbed by clouds, oceans and land.But when humans invented solar panels！A large number of photons that should have been reflected from the sun’s rays off the earth are absorbed by the solar panels; solar energy that should have been absorbed by the clouds, oceans and land is snatched by the solar panels, leaving only photons and heat energy that has nowhere to go. in the air.
Solar panels are double-edged swords.Although it absorbs photons and provides electricity for human beings to use, it does not absorb heat and makes heat energy remain in the atmosphere, which accelerates the warming of the earth’s climate!Although scientists only say that the main cause is the greenhouse effect caused by fossil fuels,indirectly cause the earth’s temperature to increase.However, the direct thermal waste energy of solar panels warms the earth, in fact, it has more impact on climate change than carbon emissions!
Smart humans should use the invention of solar panels correctly, so as not to open Pandora’s box by themselves!We should develop solar energy outside space, not in the atmosphere.As for the large amount of thermal waste energy produced by ourselves, how can we repair it?The best way is to plant a variety of trees, at least it can absorb heat and prevent landslides.
